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.","lang":"eng"}],"date_updated":"2024-09-11T08:17:16Z","citation":{"ista":"Baker J, Baker T, Carbone C, Congedo G, Contaldi C, Dvorkin I, Gair J, Haiman Z, Mota DF, Renzini A, Buis E-J, Cusin G, Ezquiaga JM, Mueller G, Pieroni M, Quenby J, Ricciardone A, Saltas ID, Shao L, Tamanini N, Tasinato G, Zumalacárregui M. 2021.

Yet many outstanding questions related to astrophysics and cosmology are best answered by GW observations in this band. We show that a μ-Hz GW detector will be a truly overarching observatory for the scientific community at large, greatly extending the potential of LISA.

To extract this extra information, accurate modelling of baryonic effects is necessary. 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. We also find that combining the lensing power spectrum and peak counts can break the degeneracy between cosmological and baryonic parameters and mitigate the impact of the uncertainty in baryonic physics.","lang":"eng"}],"_id":"17574","date_updated":"2024-09-19T07:43:16Z","page":"3406-3417","citation":{"chicago":"Lu, Tianhuan, and Zoltán Haiman. “The Impact of Baryons on Cosmological Inference from Weak Lensing Statistics.” Monthly Notices of the Royal Astronomical Society.

Rubin Observatory is expected to discover tens of millions of quasars. 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. The practical question is how to find these handful of ‘needles in the haystack’ among the large number of quasars: this will likely require a tailored co-adding analysis optimized for this purpose."}],"citation":{"chicago":"Xin, Chengcheng, and Zoltán Haiman. “Ultra-Short-Period Massive Black Hole Binary Candidates in LSST as LISA ‘Verification Binaries.’” Monthly Notices of the Royal Astronomical Society.

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."}],"oa":1,"issue":"1","type":"journal_article","article_number":"L20","oa_version":"Published Version","date_created":"2024-09-05T12:27:07Z","scopus_import":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"Eccentric black hole mergers in active galactic nuclei","article_type":"original","intvolume":" 907","author":[{"last_name":"Tagawa","first_name":"Hiromichi","full_name":"Tagawa, Hiromichi"},{"first_name":"Bence","last_name":"Kocsis","full_name":"Kocsis, Bence"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán"},{"last_name":"Bartos","first_name":"Imre","full_name":"Bartos, Imre"},{"full_name":"Omukai, Kazuyuki","last_name":"Omukai","first_name":"Kazuyuki"},{"full_name":"Samsing, Johan","last_name":"Samsing","first_name":"Johan"}],"extern":"1","year":"2021","article_processing_charge":"No"},{"month":"08","doi":"10.1093/mnras/stab2315","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/mnras/stab2315"}],"publisher":"Oxford University Press","publication_status":"published","publication":"Monthly Notices of the Royal Astronomical Society","volume":507,"publication_identifier":{"issn":["0035-8711","1365-2966"]},"day":"13","status":"public","quality_controlled":"1","language":[{"iso":"eng"}],"date_published":"2021-08-13T00:00:00Z","citation":{"mla":"Tagawa, Hiromichi, et al. “Signatures of Hierarchical Mergers in Black Hole Spin and Mass Distribution.” Monthly Notices of the Royal Astronomical Society, vol. 507, no. 3, Oxford University Press, 2021, pp. 3362–80, doi:10.1093/mnras/stab2315.","short":"H.

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)."}],"date_updated":"2024-09-19T11:50:46Z","type":"journal_article","date_created":"2024-09-05T12:30:08Z","oa_version":"Published Version","oa":1,"issue":"3","scopus_import":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"Signatures of hierarchical mergers in black hole spin and mass distribution","extern":"1","year":"2021","article_processing_charge":"No","article_type":"original","author":[{"last_name":"Tagawa","first_name":"Hiromichi","full_name":"Tagawa, Hiromichi"},{"last_name":"Haiman","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán"},{"last_name":"Bartos","first_name":"Imre","full_name":"Bartos, Imre"},{"full_name":"Kocsis, Bence","last_name":"Kocsis","first_name":"Bence"},{"first_name":"Kazuyuki","last_name":"Omukai","full_name":"Omukai, Kazuyuki"}],"intvolume":" 507"},{"main_file_link":[{"url":"https://doi.org/10.1093/mnras/stab2893","open_access":"1"}],"doi":"10.1093/mnras/stab2893","month":"10","quality_controlled":"1","day":"07","status":"public","publication_identifier":{"issn":["0035-8711","1365-2966"]},"publication":"Monthly Notices of the Royal Astronomical Society","volume":509,"publisher":"Oxford University Press","publication_status":"published","issue":"1","oa":1,"oa_version":"Published Version","date_created":"2024-09-05T12:32:01Z","type":"journal_article","page":"212-223","date_published":"2021-10-07T00:00:00Z","citation":{"mla":"Dotti, Massimo, et al. “Binary Black Hole Signatures in Polarized Light Curves.” Monthly Notices of the Royal Astronomical Society, vol. 509, no. 1, Oxford University Press, 2021, pp. 212–23, doi:10.1093/mnras/stab2893.","short":"M.

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.","lang":"eng"}],"_id":"17586","date_updated":"2024-09-19T11:55:01Z","language":[{"iso":"eng"}],"intvolume":" 509","author":[{"first_name":"Massimo","last_name":"Dotti","full_name":"Dotti, Massimo"},{"last_name":"Bonetti","first_name":"Matteo","full_name":"Bonetti, Matteo"},{"first_name":"Daniel J","last_name":"D’Orazio","full_name":"D’Orazio, Daniel J"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","first_name":"Zoltán","last_name":"Haiman"},{"full_name":"Ho, Luis C","first_name":"Luis C","last_name":"Ho"}],"article_type":"original","year":"2021","article_processing_charge":"No","extern":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"Binary black hole signatures in polarized light curves","scopus_import":"1"},{"intvolume":" 920","author":[{"full_name":"Gayathri, V.","last_name":"Gayathri","first_name":"V."},{"last_name":"Yang","first_name":"Y.","full_name":"Yang, Y."},{"full_name":"Tagawa, H.","last_name":"Tagawa","first_name":"H."},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán"},{"last_name":"Bartos","first_name":"I.","full_name":"Bartos, I."}],"article_type":"original","article_processing_charge":"No","year":"2021","extern":"1","title":"Black hole mergers of AGN origin in LIGO–Virgo’s O1–O3a observing periods","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","scopus_import":"1","issue":"2","oa":1,"oa_version":"Published Version","date_created":"2024-09-05T12:34:46Z","article_number":"L42","type":"journal_article","date_updated":"2024-09-19T12:17:28Z","_id":"17589","abstract":[{"text":"The origin of the black hole mergers detected by LIGO and Virgo remains an open question.

Based on the performance of LISA Pathfinder, it is now expected that LISA will have a duty cycle of ≈0.75 , which would reduce the effective span of usable data to 3 years. This paper reports the results of a study by the LISA Science Group, which was charged with assessing the additional science return of increasing the mission lifetime. We explore various observational scenarios to assess the impact of mission duration on the main science objectives of the mission. We find that the science investigations most affected by mission duration concern the search for seed black holes at cosmic dawn, as well as the study of stellar-origin black holes and of their formation channels via multi-band and multi-messenger observations. We conclude that an extension to 6 years of mission operations is recommended.","lang":"eng"}],"_id":"17593","date_updated":"2024-09-23T12:32:50Z","type":"journal_article","article_number":"3","date_created":"2024-09-05T12:40:14Z","oa_version":"Published Version","oa":1,"issue":"1","scopus_import":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","title":"The effect of mission duration on LISA science objectives","extern":"1","year":"2021","article_processing_charge":"No","article_type":"original","intvolume":" 54","author":[{"full_name":"Amaro Seoane, Pau","first_name":"Pau","last_name":"Amaro Seoane"},{"full_name":"Arca Sedda, Manuel","last_name":"Arca Sedda","first_name":"Manuel"},{"full_name":"Babak, Stanislav","last_name":"Babak","first_name":"Stanislav"},{"last_name":"Berry","first_name":"Christopher P.

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.","lang":"eng"}],"language":[{"iso":"eng"}],"quality_controlled":"1","external_id":{"arxiv":["2103.12755"]},"day":"22","status":"public","arxiv":1,"publication_identifier":{"issn":["0004-637X","1538-4357"]},"publication":"The Astrophysical Journal","volume":919,"publisher":"American Astronomical Society","publication_status":"published","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2103.12755","open_access":"1"}],"doi":"10.3847/1538-4357/ac106d","month":"09"},{"year":"2021","article_processing_charge":"No","extern":"1","author":[{"full_name":"Lupi, Alessandro","last_name":"Lupi","first_name":"Alessandro"},{"first_name":"Zoltán","last_name":"Haiman","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"full_name":"Volonteri, Marta","first_name":"Marta","last_name":"Volonteri"}],"intvolume":" 503","article_type":"original","title":"Forming massive seed black holes in high-redshift quasar host progenitors","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","scopus_import":"1","oa_version":"Preprint","date_created":"2024-09-05T13:22:23Z","type":"journal_article","issue":"4","oa":1,"page":"5046-5060","citation":{"short":"A.

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."}],"language":[{"iso":"eng"}],"quality_controlled":"1","external_id":{"arxiv":["2102.05051"]},"publication":"Monthly Notices of the Royal Astronomical Society","volume":503,"publisher":"Oxford University Press","publication_status":"published","day":"24","status":"public","arxiv":1,"publication_identifier":{"issn":["0035-8711","1365-2966"]},"main_file_link":[{"url":" https://doi.org/10.48550/arXiv.2102.05051","open_access":"1"}],"month":"03","doi":"10.1093/mnras/stab692"},{"article_processing_charge":"No","year":"2021","article_type":"original","author":[{"first_name":"Chiara","last_name":"Boccato","full_name":"Boccato, Chiara","id":"342E7E22-F248-11E8-B48F-1D18A9856A87"}],"intvolume":" 33","scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"The excitation spectrum of the Bose gas in the Gross-Pitaevskii regime","article_number":"2060006","type":"journal_article","date_created":"2020-04-26T22:00:45Z","oa_version":"Preprint","oa":1,"isi":1,"issue":"1","language":[{"iso":"eng"}],"_id":"7685","abstract":[{"text":"We consider a gas of interacting bosons trapped in a box of side length one in the Gross–Pitaevskii limit.

Our main result is the construction of stratification learning algorithms framed in terms of a sheaf on a partially ordered set with the Alexandroff topology. We prove that the resulting decomposition is the unique minimal stratification for which the strata are homogeneous and the given sheaf is constructible. In particular, when we choose to work with the local homology sheaf, our algorithm gives an alternative to the local homology transfer algorithm given in Bendich et al. (Proceedings of the 23rd Annual ACM-SIAM Symposium on Discrete Algorithms, pp. 1355–1370, ACM, New York, 2012), and the cohomology stratification algorithm given in Nanda (Found. Comput. Math. 20(2), 195–222, 2020). Additionally, we give examples of stratifications based on the geometric techniques of Breiding et al. (Rev. Mat. Complut. 31(3), 545–593, 2018), illustrating how the sheaf-theoretic approach can be used to study stratifications from both topological and geometric perspectives. This approach also points toward future applications of sheaf theory in the study of topological data analysis by illustrating the utility of the language of sheaf theory in generalizing existing algorithms."}],"date_updated":"2025-04-15T06:53:15Z","page":"1166-1198","department":[{"_id":"HeEd"}],"date_published":"2021-06-01T00:00:00Z","citation":{"short":"A.
