In this paper, we propose a new approach to this problem: a type system we call RefinedC, which combines ownership types (for modular reasoning about shared state and concurrency) with refinement types (for encoding precise invariants on C data types and Hoare-style specifications for C functions).\r\nRefinedC is both automated (requiring minimal user intervention) and foundational (producing a proof of program correctness in Coq), while at the same time handling a range of low-level programming idioms such as pointer arithmetic. In particular, following the approach of RustBelt, the soundness of the RefinedC type system is justified semantically by interpretation into the Coq-based Iris framework for higher-order concurrent separation logic. However, the typing rules of RefinedC are also designed to be encodable in a new “separation logic programming” language we call Lithium. By restricting to a carefully chosen (yet expressive) fragment of separation logic, Lithium supports predictable, automatic, goal-directed proof search without backtracking. We demonstrate the effectiveness of RefinedC on a range of representative examples of C code.","lang":"eng"}],"status":"public","publisher":"Association for Computing Machinery","scopus_import":"1","doi":"10.1145/3453483.3454036","date_updated":"2024-09-10T11:54:22Z"},{"year":"2021","oa_version":"Published Version","quality_controlled":"1","author":[{"last_name":"Gurvits","first_name":"Leonid I.","full_name":"Gurvits, Leonid I."},{"first_name":"Zsolt","last_name":"Paragi","full_name":"Paragi, Zsolt"},{"full_name":"Casasola, Viviana","last_name":"Casasola","first_name":"Viviana"},{"full_name":"Conway, John","last_name":"Conway","first_name":"John"},{"full_name":"Davelaar, Jordy","last_name":"Davelaar","first_name":"Jordy"},{"first_name":"Heino","last_name":"Falcke","full_name":"Falcke, Heino"},{"full_name":"Fender, Rob","last_name":"Fender","first_name":"Rob"},{"full_name":"Frey, Sándor","last_name":"Frey","first_name":"Sándor"},{"full_name":"Fromm, Christian M.","last_name":"Fromm","first_name":"Christian M."},{"full_name":"Miró, Cristina García","first_name":"Cristina García","last_name":"Miró"},{"last_name":"Garrett","first_name":"Michael A.","full_name":"Garrett, Michael A."},{"first_name":"Marcello","last_name":"Giroletti","full_name":"Giroletti, Marcello"},{"full_name":"Goddi, Ciriaco","first_name":"Ciriaco","last_name":"Goddi"},{"full_name":"Gómez, José-Luis","last_name":"Gómez","first_name":"José-Luis"},{"first_name":"Jeffrey","last_name":"van der Gucht","full_name":"van der Gucht, Jeffrey"},{"last_name":"Guirado","first_name":"José Carlos","full_name":"Guirado, José Carlos"},{"full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","first_name":"Zoltán"},{"full_name":"Helmich, Frank","last_name":"Helmich","first_name":"Frank"},{"first_name":"Elizabeth","last_name":"Humphreys","full_name":"Humphreys, Elizabeth"},{"last_name":"Impellizzeri","first_name":"Violette","full_name":"Impellizzeri, Violette"},{"first_name":"Michael","last_name":"Kramer","full_name":"Kramer, Michael"},{"full_name":"Lindqvist, Michael","first_name":"Michael","last_name":"Lindqvist"},{"full_name":"Linz, Hendrik","last_name":"Linz","first_name":"Hendrik"},{"first_name":"Elisabetta","last_name":"Liuzzo","full_name":"Liuzzo, Elisabetta"},{"full_name":"Lobanov, Andrei P.","last_name":"Lobanov","first_name":"Andrei P."},{"full_name":"Mizuno, Yosuke","last_name":"Mizuno","first_name":"Yosuke"},{"first_name":"Luciano","last_name":"Rezzolla","full_name":"Rezzolla, Luciano"},{"full_name":"Roelofs, Freek","last_name":"Roelofs","first_name":"Freek"},{"full_name":"Ros, Eduardo","last_name":"Ros","first_name":"Eduardo"},{"full_name":"Rygl, Kazi L.J.","last_name":"Rygl","first_name":"Kazi L.J."},{"full_name":"Savolainen, Tuomas","first_name":"Tuomas","last_name":"Savolainen"},{"full_name":"Schuster, Karl","first_name":"Karl","last_name":"Schuster"},{"last_name":"Venturi","first_name":"Tiziana","full_name":"Venturi, Tiziana"},{"first_name":"Martina C.","last_name":"Wiedner","full_name":"Wiedner, Martina C."},{"last_name":"Zensus","first_name":"J.

It addresses the science case and some implementation issues of a space-borne radio interferometric system for ultra-sharp imaging of celestial radio sources at the level of angular resolution down to (sub-) microarcseconds. THEZA focuses at millimetre and sub-millimetre wavelengths (frequencies above \r\n300 GHz), but allows for science operations at longer wavelengths too. The THEZA concept science rationale is focused on the physics of spacetime in the vicinity of supermassive black holes as the leading science driver. The main aim of the concept is to facilitate a major leap by providing researchers with orders of magnitude improvements in the resolution and dynamic range in direct imaging studies of the most exotic objects in the Universe, black holes. The concept will open up a sizeable range of hitherto unreachable parameters of observational astrophysics. It unifies two major lines of development of space-borne radio astronomy of the past decades: Space VLBI (Very Long Baseline Interferometry) and mm- and sub-mm astrophysical studies with “single dish” instruments. It also builds upon the recent success of the Earth-based Event Horizon Telescope (EHT) – the first-ever direct image of a shadow of the super-massive black hole in the centre of the galaxy M87. As an amalgam of these three major areas of modern observational astrophysics, THEZA aims at facilitating a breakthrough in high-resolution high image quality studies in the millimetre and sub-millimetre domain of the electromagnetic spectrum.","lang":"eng"}],"publication_identifier":{"issn":["0922-6435","1572-9508"]},"doi":"10.1007/s10686-021-09714-y","date_updated":"2024-09-10T12:15:42Z"},{"volume":908,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","month":"02","citation":{"ista":"Tagawa H, Kocsis B, Haiman Z, Bartos I, Omukai K, Samsing J. 2021.

These merging objects could have undergone previous mergers. Such hierarchical mergers are predicted to be frequent in active galactic nuclei (AGNs) disks, where binaries form and evolve efficiently by dynamical interactions and gaseous dissipation. Here we compare the properties of these observed events to the theoretical models of mergers in AGN disks, which are obtained by performing one-dimensional N-body simulations combined with semi-analytical prescriptions. The high BH masses in GW190521 are consistent with mergers of high-generation (high-g) BHs where the initial progenitor stars had high metallicity, 2g BHs if the original progenitors were metal-poor, or 1g BHs that had gained mass via super-Eddington accretion. Other measured properties related to spin parameters in GW190521 are also consistent with mergers in AGN disks. Furthermore, mergers in the lower mass gap or those with low mass ratio as found in GW190814 and GW190412 are also reproduced by mergers of 2g–1g or 1g–1g objects with significant accretion in AGN disks. Finally, due to gas accretion, the massive neutron star merger reported in GW190425 can be produced in an AGN disk."}],"title":"Mass-gap mergers in active galactic nuclei","date_published":"2021-02-24T00:00:00Z","intvolume":"       908","issue":"2","type":"journal_article","date_created":"2024-09-05T08:47:46Z","_id":"17509","article_processing_charge":"No"},{"date_created":"2024-09-05T08:55:06Z","type":"journal_article","article_processing_charge":"No","_id":"17515","intvolume":"       915","issue":"1","publication_identifier":{"issn":["0004-637X","1538-4357"]},"doi":"10.3847/1538-4357/abfdb4","date_updated":"2024-09-10T13:47:31Z","title":"Accretion-induced collapse of neutron stars in the disks of active galactic nuclei","date_published":"2021-06-28T00:00:00Z","abstract":[{"text":"The disks of active galactic nuclei (AGNs) have emerged as a rich environment for the evolution of stars and their compact remnants. The very dense medium favors rapid accretion, while torques and migration traps enhance binary formation and mergers. Both long and short gamma-ray bursts are hence expected. We show that AGN disks constitute an ideal environment for another interesting phenomenon: the accretion-induced collapse (AIC) of neutron stars (NSs) to black holes (BHs). Rapid accretion in the dense disks can cause NSs to grow to the point of exceeding the maximum mass allowed by their equation of state. General relativistic magnetohydrodynamical simulations have shown that electromagnetic signatures are expected if the NS is surrounded by a minidisk prior to collapse, which then rapidly accretes onto the BH, and/or if the NS is highly magnetized, from reconnection of the magnetosphere during collapse. Here we compute the rates of AICs and their locations within the disks for both isolated NSs and for (initially stable) NSs formed from NS-NS mergers. We find that the global AIC rates are ∼0.07–20 Gpc−3 yr−1, and we discuss their observable prospects and signatures as they emerge from the dense disk environments.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/1538-4357/abfdb4"}],"extern":"1","oa":1,"publication_status":"published","publication":"The Astrophysical Journal","language":[{"iso":"eng"}],"author":[{"first_name":"Rosalba","last_name":"Perna","full_name":"Perna, Rosalba"},{"last_name":"Tagawa","first_name":"Hiromichi","full_name":"Tagawa, Hiromichi"},{"full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","first_name":"Zoltán"},{"last_name":"Bartos","first_name":"Imre","full_name":"Bartos, Imre"}],"quality_controlled":"1","year":"2021","article_number":"10","oa_version":"Published Version","scopus_import":"1","publisher":"American Astronomical Society","status":"public","day":"28","article_type":"original","month":"06","volume":915,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"ista":"Perna R, Tagawa H, Haiman Z, Bartos I. 2021.

We quantify the baryonic effects on the WL angular power spectrum, one-point probability distribution function (PDF), and number counts of peaks and minima. We also show the redshift evolution of the effects, which is a key to distinguish the effect of baryons from fundamental physics such as dark energy, dark matter, and massive neutrinos. We find that baryonic processes reduce the small-scale power, suppress the tails of the PDF, peak and minimum counts, and change the total number of peaks and minima. We compare our results to existing semi-analytical models and hydrodynamic simulations, and discuss the source of discrepancies. The κTNG suite includes 10 000 realizations of $5 \\times 5 \\, \\mathrm{deg}^2$ maps for 40 source redshifts up to zs = 2.6, well covering the range of interest for existing and upcoming WL surveys. We also produce the κTNG-Dark suite of maps, generated based on the corresponding dark matter-only IllustrisTNG simulations. Our mock maps are not only suitable for developing analytical models that incorporate the effect of baryons, but also particularly useful for studies that rely on mass maps, such as non-Gaussian statistics and machine learning with convolutional neural networks. The suite of mock maps is publicly available at Columbia Lensing (http://columbialensing.org)."}],"date_published":"2021-02-11T00:00:00Z","title":"κTNG: effect of baryonic processes on weak lensing with IllustrisTNG simulations","date_updated":"2024-09-10T13:53:06Z","doi":"10.1093/mnras/stab395","publication_identifier":{"issn":["0035-8711","1365-2966"]},"language":[{"iso":"eng"}],"publication":"Monthly Notices of the Royal Astronomical Society","publication_status":"published","oa":1,"extern":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stab395"}],"_id":"17516","article_processing_charge":"No","type":"journal_article","date_created":"2024-09-05T08:56:14Z","page":"5593-5602","issue":"4","intvolume":"       502"},{"intvolume":"        51","issue":"3","date_created":"2024-09-05T09:28:30Z","page":"1441-1470","type":"journal_article","article_processing_charge":"No","_id":"17525","main_file_link":[{"url":"https://doi.org/10.1007/s10686-021-09712-0","open_access":"1"}],"publication":"Experimental Astronomy","publication_status":"published","oa":1,"extern":"1","language":[{"iso":"eng"}],"doi":"10.1007/s10686-021-09712-0","publication_identifier":{"issn":["0922-6435","1572-9508"]},"date_updated":"2024-09-11T08:17:16Z","date_published":"2021-05-04T00:00:00Z","title":"High angular resolution gravitational wave astronomy","abstract":[{"lang":"eng","text":"Since the very beginning of astronomy the location of objects on the sky has been a fundamental observational quantity that has been taken for granted. While precise two dimensional positional information is easy to obtain for observations in the electromagnetic spectrum, the positional accuracy of current and near future gravitational wave detectors is limited to between tens and hundreds of square degrees, which makes it extremely challenging to identify the host galaxies of gravitational wave events or to detect any electromagnetic counterparts. Gravitational wave observations provide information on source properties that is complementary to the information in any associated electromagnetic emission. Observing systems with multiple messengers thus has scientific potential much greater than the sum of its parts. A gravitational wave detector with higher angular resolution would significantly increase the prospects for finding the hosts of gravitational wave sources and triggering a multi-messenger follow-up campaign. An observatory with arcminute precision or better could be realised within the Voyage 2050 programme by creating a large baseline interferometer array in space and would have transformative scientific potential. Precise positional information of standard sirens would enable precision measurements of cosmological parameters and offer new insights on structure formation; a high angular resolution gravitational wave observatory would allow the detection of a stochastic background and resolution of the anisotropies within it; it would also allow the study of accretion processes around black holes; and it would have tremendous potential for tests of modified gravity and the discovery of physics beyond the Standard Model."}],"quality_controlled":"1","year":"2021","oa_version":"Published Version","author":[{"full_name":"Baker, John","last_name":"Baker","first_name":"John"},{"last_name":"Baker","first_name":"Tessa","full_name":"Baker, Tessa"},{"full_name":"Carbone, Carmelita","first_name":"Carmelita","last_name":"Carbone"},{"last_name":"Congedo","first_name":"Giuseppe","full_name":"Congedo, Giuseppe"},{"full_name":"Contaldi, Carlo","last_name":"Contaldi","first_name":"Carlo"},{"full_name":"Dvorkin, Irina","last_name":"Dvorkin","first_name":"Irina"},{"full_name":"Gair, Jonathan","last_name":"Gair","first_name":"Jonathan"},{"last_name":"Haiman","first_name":"Zoltán","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"full_name":"Mota, David F.","last_name":"Mota","first_name":"David F."},{"full_name":"Renzini, Arianna","last_name":"Renzini","first_name":"Arianna"},{"last_name":"Buis","first_name":"Ernst-Jan","full_name":"Buis, Ernst-Jan"},{"full_name":"Cusin, Giulia","first_name":"Giulia","last_name":"Cusin"},{"first_name":"Jose Maria","last_name":"Ezquiaga","full_name":"Ezquiaga, Jose Maria"},{"last_name":"Mueller","first_name":"Guido","full_name":"Mueller, Guido"},{"first_name":"Mauro","last_name":"Pieroni","full_name":"Pieroni, Mauro"},{"last_name":"Quenby","first_name":"John","full_name":"Quenby, John"},{"last_name":"Ricciardone","first_name":"Angelo","full_name":"Ricciardone, Angelo"},{"first_name":"Ippocratis D.","last_name":"Saltas","full_name":"Saltas, Ippocratis D."},{"full_name":"Shao, Lijing","last_name":"Shao","first_name":"Lijing"},{"last_name":"Tamanini","first_name":"Nicola","full_name":"Tamanini, Nicola"},{"full_name":"Tasinato, Gianmassimo","first_name":"Gianmassimo","last_name":"Tasinato"},{"full_name":"Zumalacárregui, Miguel","last_name":"Zumalacárregui","first_name":"Miguel"}],"month":"05","volume":51,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"chicago":"Baker, John, Tessa Baker, Carmelita Carbone, Giuseppe Congedo, Carlo Contaldi, Irina Dvorkin, Jonathan Gair, et al. “High Angular Resolution Gravitational Wave Astronomy.” <i>Experimental Astronomy</i>.

In this work, we adopt a baryonic correction model, which includes gas both bound inside and ejected from dark matter (DM) haloes, a central galaxy, and changes in the DM profile induced by baryons. We use this model to incorporate baryons into a large suite of DM-only N-body simulations, covering a grid of 75 cosmologies in the Ωm–σ8 parameter space. We investigate how baryons affect Gaussian and non-Gaussian weak lensing statistics and the cosmological parameter inferences from these statistics. Our results show that marginalizing over baryonic parameters degrades the constraints in Ωm–σ8 space by a factor of 2–5 compared to those with baryonic parameters fixed.

A significant fraction of these could be powered by coalescing massive black hole (MBH) binaries, since many quasars are believed to be triggered by mergers. We show that under plausible assumptions about the luminosity functions, lifetimes, and binary fractions of quasars, we expect the full LSST quasar catalogue to contain between 20 and 100 million compact MBH binaries with masses M = 105–9M⊙, redshifts z = 0–6, and orbital periods P = 1–70 d. Their light-curves are expected to be distinctly periodic, which can be confidently distinguished from stochastic red-noise variability, because LSST will cover dozens, or even hundreds of cycles. A very small subset of 10–150 ultracompact (P ≲ 1 d) binary quasars among these will, over ∼5–15 yr, evolve into the mHz gravitational-wave frequency band and can be detected by LISA. They can therefore be regarded as ‘LISA verification binaries’, analogous to short-period Galactic compact-object binaries.

In active galactic nuclei (AGNs), binaries form and evolve efficiently by interaction with a dense population of stars and the gaseous AGN disk. Previous studies have shown that stellar-mass black hole (BH) mergers in such environments can explain the merger rate and the number of suspected hierarchical mergers observed by LIGO/Virgo. The binary eccentricity distribution can provide further information to distinguish between astrophysical models. Here we derive the eccentricity distribution of BH mergers in AGN disks. We find that eccentricity is mainly due to binary–single (BS) interactions, which lead to most BH mergers in AGN disks having a significant eccentricity at 0.01 Hz, detectable by the Laser Interferometer Space Antenna. If BS interactions occur in isotropic-3D directions, then 8%–30% of the mergers in AGN disks will have eccentricities at 10 Hz above e10 Hz ≳ 0.03, detectable by LIGO/Virgo/Kamioka Gravitational Wave Detector, while 5%–17% of mergers have e10 Hz ≥ 0.3. On the other hand, if BS interactions are confined to the AGN–disk plane due to torques from the disk, with 1–20 intermediate binary states during each interaction, or if BHs can migrate to ≲ 10−3 pc from the central supermassive BH, then 10%–70% of the mergers will be highly eccentric (e10 Hz ≥ 0.3), consistent with the possible high eccentricity in GW190521."}],"intvolume":"       907","issue":"1","date_created":"2024-09-05T12:27:07Z","type":"journal_article","article_processing_charge":"No","_id":"17583","month":"01","volume":907,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"ista":"Tagawa H, Kocsis B, Haiman Z, Bartos I, Omukai K, Samsing J. 2021.

These events may carry important clues about the astrophysical host environments of the GW sources. In this paper, we present the distributions of the effective spin parameter (χeff), the precession spin parameter (χp), and the chirp mass (mchirp) expected in hierarchical mergers. Under a wide range of assumptions, hierarchical mergers produce (i) a monotonic increase of the average of the typical total spin for merging binaries, which we characterize with χ¯typ≡(χ2eff+χ2p)1/2¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯, up to roughly the maximum mchirp among first-generation (1g) BHs, and (ii) a plateau at χ¯typ∼0.6 at higher mchirp. We suggest that the maximum mass and typical spin magnitudes for 1g BHs can be estimated from χ¯typ as a function of mchirp. The GW data observed in LIGO/Virgo O1--O3a prefers an increase in χ¯typ at low mchirp, which is consistent with the growth of the BH spin magnitude by hierarchical mergers, at ∼2σ confidence. A Bayesian analysis suggests that 1g BHs have the maximum mass of ∼15--30M⊙ if the majority of mergers are of high-generation BHs (not among 1g-1g BHs), which is consistent with mergers in active galactic nucleus disks and/or nuclear star clusters, while if mergers mainly originate from globular clusters, 1g BHs are favored to have non-zero spin magnitudes of ∼0.3. We also forecast that signatures for hierarchical mergers in the χ¯typ distribution can be confidently recovered once the number of GW events increases to ≳O(100).","lang":"eng"}],"quality_controlled":"1","year":"2021","oa_version":"Published Version","author":[{"full_name":"Tagawa, Hiromichi","last_name":"Tagawa","first_name":"Hiromichi"},{"first_name":"Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán"},{"full_name":"Bartos, Imre","last_name":"Bartos","first_name":"Imre"},{"last_name":"Kocsis","first_name":"Bence","full_name":"Kocsis, Bence"},{"last_name":"Omukai","first_name":"Kazuyuki","full_name":"Omukai, Kazuyuki"}],"month":"08","volume":507,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"ista":"Tagawa H, Haiman Z, Bartos I, Kocsis B, Omukai K. 2021.

In such scenarios, the periodicity can be due to relativistic Doppler-boosting of the emitted light. This hypothesis can be tested through the timing of scattered polarized light. Following the results of polarization studies in type I nuclei and of dynamical studies of MBHBs with circumbinary discs, we assume a coplanar equatorial scattering ring, whose elements contribute differently to the total polarized flux, due to different scattering angles, levels of Doppler boost, and line-of-sight time delays. We find that in the presence of an MBHB, both the degree of polarization and the polarization position angle have periodic modulations. The polarization angle oscillates around the semiminor axis of the projected MBHB orbital ellipse, with a frequency equal either to the binary’s orbital frequency (for large scattering screen radii), or twice this value (for smaller scattering structures). These distinctive features can be used to probe the nature of periodic MBHB candidates and to compile catalogues of the most promising sub-pc MBHBs. The identification of such polarization features in gravitational-wave (GW) detected MBHBs would enormously increase the amount of physical information about the sources, allowing the measurement of the individual masses of the binary components, and the orientation of the line of nodes on the sky, even for monochromatic GW signals."}],"main_file_link":[{"url":"https://doi.org/10.1093/mnras/stab2893","open_access":"1"}],"publication":"Monthly Notices of the Royal Astronomical Society","publication_status":"published","oa":1,"extern":"1","language":[{"iso":"eng"}],"date_created":"2024-09-05T12:32:01Z","page":"212-223","type":"journal_article","article_processing_charge":"No","_id":"17586","intvolume":"       509","issue":"1"},{"extern":"1","oa":1,"publication":"The Astrophysical Journal Letters","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/2041-8213/ac2cc1"}],"title":"Black hole mergers of AGN origin in LIGO–Virgo’s O1–O3a observing periods","date_published":"2021-10-21T00:00:00Z","abstract":[{"text":"The origin of the black hole mergers detected by LIGO and Virgo remains an open question.

A stochastic gravitational wave background (GWB) is a useful tool to probe the cosmological evolution of those compact mergers. In this paper, we study the upper bound on a GWB produced by BBH mergers, whose stellar progenitors dominate the reionization process at the cosmic dawn. Since early reionization by those progenitors yields a high optical depth of the universe inconsistent with the {\\it Planck} measurements, the cumulative mass density is limited to ρ⋆≲107 M⊙ Mpc−3. Even with this upper bound, the amplitude of a GWB owing to the high-z BBH mergers is expected to be as high as Ωgw≃1.48+1.80−1.27×10−9 at f≃25 Hz, while their merger rate at the present-day is consistent or lower than the observed GW event rate. This level of GWB is detectable at the design sensitivity of Advanced LIGO-Virgo and would indicate a major contribution of the high-z BBH population to the local GW events. The spectral index is expected to be substantially flatter than the canonical value of ≃2/3 generically produced by lower-redshift and less massive BBHs. Moreover, if their mass function is more top-heavy than in the local universe, the GWB spectrum is even more skewed toward lower frequencies, which would allow us to extract information on the mass function of merging BBHs at high redshifts."}],"publication_identifier":{"issn":["0004-637X","1538-4357"]},"doi":"10.3847/1538-4357/ac106d","date_updated":"2024-09-23T13:08:15Z"},{"doi":"10.1093/mnras/stab692","publication_identifier":{"issn":["0035-8711","1365-2966"]},"date_updated":"2024-09-23T14:49:49Z","date_published":"2021-03-24T00:00:00Z","title":"Forming massive seed black holes in high-redshift quasar host progenitors","abstract":[{"text":"The presence of massive black holes (BHs) with masses of order 109M⊙, powering bright quasars when the Universe was less than 1 Gyr old, poses strong constraints on their formation mechanism. Several scenarios have been proposed to date to explain massive BH formation, from the low-mass seed BH remnants of the first generation of stars to the massive seed BHs resulting from the rapid collapse of massive gas clouds. However, the plausibility of some of these scenarios to occur within the progenitors of high-z quasars has not yet been thoroughly explored. In this work, we investigate, by combining dark-matter only N-body simulations with a semi-analytic framework, whether the conditions for the formation of massive seed BHs from synchronised atomic-cooling halo pairs and/or dynamically-heated mini-haloes are fulfilled in the overdense regions where the progenitors of a typical high-redshift quasar host form and evolve. Our analysis shows that the peculiar conditions in such regions, i.e. strong halo clustering and high star formation rates, are crucial to produce a non-negligible number of massive seed BH host candidates: we find ≈1400 dynamically heated metal-free mini-haloes, including one of these which evolves to a synchronised pair and ends up in the massive quasar-host halo by z=6. This demonstrates that the progenitors of high-redshift quasar host haloes can harbour early massive seed BHs. Our results further suggest that multiple massive seed BHs may form in or near the quasar host's progenitors, potentially merging at lower redshifts and yielding gravitational wave events.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2102.05051"}],"publication_status":"published","publication":"Monthly Notices of the Royal Astronomical Society","oa":1,"extern":"1","language":[{"iso":"eng"}],"date_created":"2024-09-05T13:22:23Z","page":"5046-5060","type":"journal_article","arxiv":1,"article_processing_charge":"No","_id":"17610","intvolume":"       503","issue":"4","publisher":"Oxford University Press","status":"public","scopus_import":"1","day":"24","article_type":"original","month":"03","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"arxiv":["2102.05051"]},"volume":503,"citation":{"short":"A.

It relies on repeatedly forming and rupturing a Au contact in an environment of the target molecules. The probability of junction formation is typically very high (∼70–95%), prompting questions relating to how the nanoscale structure of the Au electrode before the metal point contact ruptures alters junction formation. Here we analyze conductance traces measured with the STM-BJ setup by combining correlation analysis and multiple machine learning tools, including gradient-boosted trees and neural networks. We show that two key features describing the Au–Au contact prior to rupture determine the extent of contact relaxation (snapback) and the probability of junction formation. Importantly, our data strongly indicate that molecular junctions are formed prior to the rupture of the Au–Au contact, explaining the high probability of junction formation observed in room-temperature solution measurements."}],"publication_identifier":{"issn":["1948-7185"]},"doi":"10.1021/acs.jpclett.1c03160","date_updated":"2024-12-10T10:03:05Z","extern":"1","publication_status":"published","publication":"The Journal of Physical Chemistry Letters","language":[{"iso":"eng"}],"pmid":1},{"type":"journal_article","date_created":"2024-09-06T13:11:31Z","page":"695-710","_id":"17877","article_processing_charge":"No","intvolume":"         5","issue":"10","date_updated":"2024-12-10T10:05:51Z","doi":"10.1038/s41570-021-00316-y","publication_identifier":{"issn":["2397-3358"]},"abstract":[{"text":"Chemical reactions that occur at nanostructured electrodes have garnered widespread interest because of their potential applications in fields including nanotechnology, green chemistry and fundamental physical organic chemistry. Much of our present understanding of these reactions comes from probes that interrogate ensembles of molecules undergoing various stages of the transformation concurrently. Exquisite control over single-molecule reactivity lets us construct new molecules and further our understanding of nanoscale chemical phenomena. We can study single molecules using instruments such as the scanning tunnelling microscope, which can additionally be part of a mechanically controlled break junction. These are unique tools that can offer a high level of detail. They probe the electronic conductance of individual molecules and catalyse chemical reactions by establishing environments with reactive metal sites on nanoscale electrodes. This Review describes how chemical reactions involving bond cleavage and formation can be triggered at nanoscale electrodes and studied one molecule at a time.","lang":"eng"}],"date_published":"2021-08-25T00:00:00Z","title":"A single-molecule blueprint for synthesis","pmid":1,"language":[{"iso":"eng"}],"publication_status":"published","publication":"Nature Reviews Chemistry","extern":"1","author":[{"full_name":"Stone, Ilana","last_name":"Stone","first_name":"Ilana"},{"first_name":"Rachel L.","last_name":"Starr","full_name":"Starr, Rachel L."},{"full_name":"Zang, Yaping","last_name":"Zang","first_name":"Yaping"},{"first_name":"Colin","last_name":"Nuckolls","full_name":"Nuckolls, Colin"},{"first_name":"Michael L.","last_name":"Steigerwald","full_name":"Steigerwald, Michael L."},{"full_name":"Lambert, Tristan H.","first_name":"Tristan H.","last_name":"Lambert"},{"first_name":"Xavier","last_name":"Roy","full_name":"Roy, Xavier"},{"first_name":"Latha","orcid":"0000-0002-6957-6089","last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha"}],"quality_controlled":"1","oa_version":"None","year":"2021","OA_type":"closed access","scopus_import":"1","status":"public","publisher":"Springer Nature","article_type":"review","day":"25","external_id":{"pmid":["37118183"]},"volume":5,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"08","citation":{"mla":"Stone, Ilana, et al. “A Single-Molecule Blueprint for Synthesis.” <i>Nature Reviews Chemistry</i>, vol. 5, no. 10, Springer Nature, 2021, pp. 695–710, doi:<a href=\"https://doi.org/10.1038/s41570-021-00316-y\">10.1038/s41570-021-00316-y</a>.","short":"I.
