--- _id: '15149' abstract: - lang: eng text: The genomic binding sites of the transcription factor (TF) and tumor suppressor p53 are unusually diverse with regard to their chromatin features, including histone modifications, raising the possibility that the local chromatin environment can contextualize p53 regulation. Here, we show that epigenetic characteristics of closed chromatin, such as DNA methylation, do not influence the binding of p53 across the genome. Instead, the ability of p53 to open chromatin and activate its target genes is locally restricted by its cofactor Trim24. Trim24 binds to both p53 and unmethylated histone 3 lysine 4 (H3K4), thereby preferentially localizing to those p53 sites that reside in closed chromatin, whereas it is deterred from accessible chromatin by H3K4 methylation. The presence of Trim24 increases cell viability upon stress and enables p53 to affect gene expression as a function of the local chromatin state. These findings link H3K4 methylation to p53 function and illustrate how specificity in chromatin can be achieved, not by TF-intrinsic sensitivity to histone modifications, but by employing chromatin-sensitive cofactors that locally modulate TF function. article_processing_charge: No article_type: original author: - first_name: Luke full_name: Isbel, Luke last_name: Isbel - first_name: Murat full_name: Iskar, Murat last_name: Iskar - first_name: Sevi full_name: Durdu, Sevi last_name: Durdu - first_name: Joscha full_name: Weiss, Joscha last_name: Weiss - first_name: Ralph S. full_name: Grand, Ralph S. last_name: Grand - first_name: Eric full_name: Hietter-Pfeiffer, Eric last_name: Hietter-Pfeiffer - first_name: Zuzanna full_name: Kozicka, Zuzanna last_name: Kozicka - first_name: Alicia full_name: Michael, Alicia id: 6437c950-2a03-11ee-914d-d6476dd7b75c last_name: Michael orcid: 0000-0002-6080-839X - first_name: Lukas full_name: Burger, Lukas last_name: Burger - first_name: Nicolas H. full_name: Thomä, Nicolas H. last_name: Thomä - first_name: Dirk full_name: Schübeler, Dirk last_name: Schübeler citation: ama: Isbel L, Iskar M, Durdu S, et al.

This is the final piece of the puzzle for enumerating fixed-rank matroids at this level of accuracy: the numbers of rank-1 and rank-2 matroids on a ground set of size n have exact representations in terms of well-known combinatorial functions, and it was recently proved by van der Hofstad, Pendavingh, and van der Pol that for constant r≥4 there are (e1−rn+o(n))nr−1/r! rank-r matroids on a ground set of size n. In our proof, we introduce a new approach for bounding the number of clique decompositions of a complete graph, using quasirandomness instead of the so-called entropy method that is common in this area.' acknowledgement: "Sah and Sawhney were supported by NSF Graduate Research Fellowship Program DGE-1745302.

We find that the source is significantly polarized at about or above 20 per cent for all phases except for the secondary peak where it is more weakly polarized. The polarization degree is strongest during the primary minimum which is also the phase where an absorption feature has been identified previously. The polarization angle of the photons are consistent with a rotating vector model with a mode switch between the primary minimum and the rest of the rotation of the neutron star. We propose a scenario in which the emission at the source is weakly polarized (as in a condensed surface) and, as the radiation passes through a plasma arch, resonant cyclotron scattering off of protons produces the observed polarized radiation. This confirms the magnetar nature of the source with a surface field greater than about 1015 G. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Jeremy full_name: Heyl, Jeremy last_name: Heyl -

Two of these candidates have masses estimated from Gaia photometry of approximately 1.1 solar masses; their status as products of single-stellar evolution that have escaped the cluster was deemed too questionable for immediate follow-up analysis. The remaining candidate has an expected mass >1.3 solar masses, significantly reducing the probability of it being an interloper. Analysis of follow-up Gemini GMOS spectroscopy for this source reveals a nonmagnetized hydrogen atmosphere white dwarf with a mass and age consistent with having formed from a single star. Assuming a single-stellar-evolution formation channel, we estimate a 97.8% chance that the candidate is a true escapee from the Hyades. With a determined mass of 1.317 solar masses, this is potentially the most massive known single-evolution white dwarf and is by far the most massive with a strong association with an open cluster. article_number: L41 article_processing_charge: No article_type: original arxiv: 1 author: - first_name: David R. full_name: Miller, David R. last_name: Miller - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Jeremy full_name: Heyl, Jeremy last_name: Heyl - first_name: Harvey B. full_name: Richer, Harvey B. last_name: Richer - first_name: Kareem full_name: El-Badry, Kareem last_name: El-Badry - first_name: Antonio C. full_name: Rodriguez, Antonio C. last_name: Rodriguez - first_name: Zachary P. full_name: Vanderbosch, Zachary P. last_name: Vanderbosch - first_name: Jan full_name: van Roestel, Jan last_name: van Roestel citation: ama: Miller DR, Caiazzo I, Heyl J, et al.

Considering the observed spectral variability and changes in the pulse profiles, the source was likely caught in supercritical and subcritical states with significantly different emission-region geometry, associated with the presence of accretion columns and hot spots, respectively. We focus here on the pulse-phase-resolved polarimetric analysis and find that the observed dependencies of the polarization degree and polarization angle (PA) on the pulse phase are indeed drastically different for the two observations. The observed differences, if interpreted within the framework of the rotating vector model (RVM), imply dramatic variations in the spin axis inclination, the position angle, and the magnetic colatitude by tens of degrees within the space of just a few days. We suggest that the apparent changes in the observed PA phase dependence are predominantly related to the presence of an unpulsed polarized component in addition to the polarized radiation associated with the pulsar itself. We then show that the observed PA phase dependence in both observations can be explained with a single set of RVM parameters defining the pulsar’s geometry. We also suggest that the additional polarized component is likely produced by scattering of the pulsar radiation in the equatorial disk wind. article_number: A57 article_processing_charge: No article_type: original arxiv: 1 author: -

Some AM CVn systems will be among the loudest sources of gravitational waves for the upcoming Laser Interferometer Space Antenna; yet the formation channel of AM CVns remains uncertain. We report the study and characterization of a new eclipsing AM CVn, SRGeJ045359.9+622444 (hereafter, SRGeJ0453), discovered from a joint Spektrum-Roentgen-Gamma (SRG) Extended Roentgen Survey with an Imaging Telescope Array (eROSITA) mission and Zwicky Transient Facility program to identify cataclysmic variables (CVs). We obtained optical photometry to confirm the eclipse of SRGeJ0453 and determine the orbital period to be \r\n. We constrain the binary parameters by modeling the high-speed photometry and radial-velocity curves and find Mdonor = 0.044 ± 0.024M⊙ and Rdonor = 0.078 ± 0.012R⊙. The X-ray spectrum is approximated by a power-law model with an unusually flat photon index of Γ ∼ 1 previously seen in magnetic CVs with SRG/eROSITA, but verifying that the magnetic nature of SRGeJ0453 requires further investigation. Optical spectroscopy suggests that the donor star of SRGeJ0453 could have initially been a He star or a He white dwarf. SRGeJ0453 is the ninth eclipsing AM CVn system published to date, and its lack of optical outbursts have made it elusive in previous surveys. The discovery of SRGeJ0453 using joint X-ray and optical surveys highlights the potential for discovering similar systems in the near future." article_number: '63' article_processing_charge: No article_type: original author: - first_name: Antonio C. full_name: Rodriguez, Antonio C. last_name: Rodriguez - first_name: Ilkham full_name: Galiullin, Ilkham last_name: Galiullin - first_name: Marat full_name: Gilfanov, Marat last_name: Gilfanov - first_name: Shrinivas R. full_name: Kulkarni, Shrinivas R. last_name: Kulkarni - first_name: Irek full_name: Khamitov, Irek last_name: Khamitov - first_name: Ilfan full_name: Bikmaev, Ilfan last_name: Bikmaev - first_name: Jan full_name: van Roestel, Jan last_name: van Roestel - first_name: Lev full_name: Yungelson, Lev last_name: Yungelson - first_name: Kareem full_name: El-Badry, Kareem last_name: El-Badry - first_name: Rashid full_name: Sunayev, Rashid last_name: Sunayev - first_name: Thomas A. full_name: Prince, Thomas A. last_name: Prince - first_name: Mikhail full_name: Buntov, Mikhail last_name: Buntov - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Andrew full_name: Drake, Andrew last_name: Drake - first_name: Mark full_name: Gorbachev, Mark last_name: Gorbachev - first_name: Matthew J. full_name: Graham, Matthew J. last_name: Graham - first_name: Rustam full_name: Gumerov, Rustam last_name: Gumerov - first_name: Eldar full_name: Irtuganov, Eldar last_name: Irtuganov - first_name: Russ R. full_name: Laher, Russ R. last_name: Laher - first_name: Frank J. full_name: Masci, Frank J. last_name: Masci - first_name: Pavel full_name: Medvedev, Pavel last_name: Medvedev - first_name: Josiah full_name: Purdum, Josiah last_name: Purdum - first_name: Nail full_name: Sakhibullin, Nail last_name: Sakhibullin - first_name: Alexander full_name: Sklyanov, Alexander last_name: Sklyanov - first_name: Roger full_name: Smith, Roger last_name: Smith - first_name: Paula full_name: Szkody, Paula last_name: Szkody - first_name: Zachary P. full_name: Vanderbosch, Zachary P. last_name: Vanderbosch citation: ama: 'Rodriguez AC, Galiullin I, Gilfanov M, et al.

Several mechanisms compete with gravitational settling to change a white dwarf’s surface composition as it cools3, and the fraction of white dwarfs with helium atmospheres is known to increase by a factor of about 2.5 below a temperature of about 30,000 kelvin4,5,6,7,8; therefore, some white dwarfs that appear to have hydrogen-dominated atmospheres above 30,000 kelvin are bound to transition to be helium-dominated as they cool below it. Here we report observations of ZTF J203349.8+322901.1, a transitioning white dwarf with two faces: one side of its atmosphere is dominated by hydrogen and the other one by helium. This peculiar nature is probably caused by the presence of a small magnetic field, which creates an inhomogeneity in temperature, pressure or mixing strength over the surface9,10,11. ZTF J203349.8+322901.1 might be the most extreme member of a class of magnetic, transitioning white dwarfs—together with GD 323 (ref. 12), a white dwarf that shows similar but much more subtle variations. This class of white dwarfs could help shed light on the physical mechanisms behind the spectral evolution of white dwarfs.' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Kevin B. full_name: Burdge, Kevin B. last_name: Burdge - first_name: Pier-Emmanuel full_name: Tremblay, Pier-Emmanuel last_name: Tremblay - first_name: James full_name: Fuller, James last_name: Fuller - first_name: Lilia full_name: Ferrario, Lilia last_name: Ferrario - first_name: Boris T. full_name: Gänsicke, Boris T. last_name: Gänsicke - first_name: J.

The system contains a white dwarf accretor, which likely originated as a post–common envelope carbon–oxygen (CO) white dwarf, and a warm donor (Teff,donor = 16,400 ± 1000 K). The donor probably formed during a common envelope phase between the CO white dwarf and an evolving giant that left behind a helium star or white dwarf in a close orbit with the CO white dwarf. We measure gravitational wave–driven orbital inspiral with ∼51σ significance, which yields a joint constraint on the component masses and mass transfer rate. While the accretion disk in the system is dominated by ionized helium emission, the donor exhibits a mixture of hydrogen and helium absorption lines. Phase-resolved spectroscopy yields a donor radial velocity semiamplitude of 771 ± 27 km s−1, and high-speed photometry reveals that the system is eclipsing. We detect a Chandra X-ray counterpart with LX ∼ 3 × 1031 erg s−1. Depending on the mass transfer rate, the system will likely either evolve into a stably mass-transferring helium cataclysmic variable, merge to become an R CrB star, or explode as a Type Ia supernova in the next million years. We predict that the Laser Space Interferometer Antenna (LISA) will detect the source with a signal-to-noise ratio of 24 ± 6 after 4 yr of observations. The system is the first LISA-loud mass-transferring binary with an intrinsically luminous donor, a class of sources that provide the opportunity to leverage the synergy between optical and infrared time domain surveys, X-ray facilities, and gravitational-wave observatories to probe general relativity, accretion physics, and binary evolution. article_number: L1 article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Kevin B. full_name: Burdge, Kevin B. last_name: Burdge - first_name: Kareem full_name: El-Badry, Kareem last_name: El-Badry - first_name: Saul full_name: Rappaport, Saul last_name: Rappaport - first_name: Tin Long full_name: Sunny Wong, Tin Long last_name: Sunny Wong - first_name: Evan B. full_name: Bauer, Evan B. last_name: Bauer - first_name: Lars full_name: Bildsten, Lars last_name: Bildsten - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Deepto full_name: Chakrabarty, Deepto last_name: Chakrabarty - first_name: Emma full_name: Chickles, Emma last_name: Chickles - first_name: Matthew J. full_name: Graham, Matthew J. last_name: Graham - first_name: Erin full_name: Kara, Erin last_name: Kara - first_name: S.

The heliocentric orbit and approximate absolute magnitude of Dinkinesh are known, but little additional information was available prior to its selection as a target. In particular, the lack of color spectrophotometry or spectra made it impossible to assign a spectral type to Dinkinesh from which its albedo could be estimated. We set out to remedy this knowledge gap by obtaining visible wavelength spectra with the Keck telescope on 2022 November 23 and with Gemini-South on 2022 December 27. The spectra measured with the Keck I/Low Resolution Imaging Spectrometer (LRIS) and the Gemini South/Gemini Multi-Object Spectrograph South (GMOS-S) are most similar to the average spectrum of S- and Sq-type asteroids. The most diagnostic feature is the ≈15 ± 1% silicate absorption feature at ≈0.9–1.0 μm. Small S- and Sq-type asteroids have moderately high albedos ranging from 0.17 to 0.35. Using this albedo range for Dinkinesh in combination with measured absolute magnitude, it is possible to derive an effective diameter and surface brightness for this body. The albedo, size and surface brightness are important inputs required for planning a successful encounter by the Lucy spacecraft. article_number: '115562' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: B.T. full_name: Bolin, B.T. last_name: Bolin - first_name: K.S. full_name: Noll, K.S. last_name: Noll - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: C. full_name: Fremling, C. last_name: Fremling - first_name: R.P. full_name: Binzel, R.P. last_name: Binzel citation: ama: Bolin BT, Noll KS, Caiazzo I, Fremling C, Binzel RP.

To explore this explanation, we investigate the kinematics of ultramassive white dwarfs within 200 pc of the Sun using the improved Gaia Early Data Release 3 observations. We analyse the transverse motions of 0.95–1.25 M⊙ white dwarfs, subdivided by mass and age, and determine the distributions of the three-dimensional components of the transverse velocities. The results are compared to expectations based on observed kinematics of local main-sequence stars. We find a population of photometrically young (∼0.5–1.5 Gyr) ultramassive (∼1.15–1.25 M⊙) white dwarfs for which the transverse velocity component in the direction of Galactic rotation is more dispersed than for local disc stars of any age; thus, it is too dispersed to be explained by any cooling delay in white dwarfs originating from the local disc. Furthermore, the dispersion ratio of the velocity components in the Galactic plane for this population is also inconsistent with a local disc origin. We discuss some possible explanations of this kinematically anomalous population, such as a halo origin or production through dynamical effects of stellar triple systems. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Leesa full_name: Fleury, Leesa last_name: Fleury - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Jeremy full_name: Heyl, Jeremy last_name: Heyl citation: ama: 'Fleury L, Caiazzo I, Heyl J.

The eROSITA telescope on board the Spektr-RG mission is conducting an all-sky X-ray survey and recently released the public eROSITA Final Equatorial Depth Survey (eFEDS) catalog. We crossmatched the eFEDS catalog with photometry from the Zwicky Transient Facility and discovered two new magnetic CVs. We obtained high-cadence optical photometry and phase-resolved spectroscopy for each magnetic CV candidate and found them both to be polars. Among the newly discovered magnetic CVs is eFEDS J085037.2+044359/ZTFJ0850+0443, an eclipsing polar with orbital period Porb = 1.72 hr and WD mass MWD = 0.81 ± 0.08M⊙. We suggest that eFEDS J085037.2+044359/ZTFJ0850+0443 is a low magnetic field strength polar, with BWD ≲ 10 MG. We also discovered a non-eclipsing polar, eFEDS J092614.1+010558/ZTFJ0926+0105, with orbital period Porb = 1.47 hr and magnetic field strength BWD = 36–42 MG. article_number: '141' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Antonio C. full_name: Rodriguez, Antonio C. last_name: Rodriguez - first_name: Shrinivas R. full_name: Kulkarni, Shrinivas R. last_name: Kulkarni - first_name: Thomas A. full_name: Prince, Thomas A. last_name: Prince - first_name: Paula full_name: Szkody, Paula last_name: Szkody - first_name: Kevin B. full_name: Burdge, Kevin B. last_name: Burdge - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Jan full_name: van Roestel, Jan last_name: van Roestel - first_name: Zachary P. full_name: Vanderbosch, Zachary P. last_name: Vanderbosch - first_name: Kareem full_name: El-Badry, Kareem last_name: El-Badry - first_name: Eric C. full_name: Bellm, Eric C. last_name: Bellm - first_name: Boris T. full_name: Gänsicke, Boris T. last_name: Gänsicke - first_name: Matthew J. full_name: Graham, Matthew J. last_name: Graham - first_name: Ashish A. full_name: Mahabal, Ashish A. last_name: Mahabal - first_name: Frank J. full_name: Masci, Frank J. last_name: Masci - first_name: Przemek full_name: Mróz, Przemek last_name: Mróz - first_name: Reed full_name: Riddle, Reed last_name: Riddle - first_name: Ben full_name: Rusholme, Ben last_name: Rusholme citation: ama: Rodriguez AC, Kulkarni SR, Prince TA, et al.

We apply the unbinned technique to models of the luminous X-ray pulsar Hercules X-1, for which we produce simulated observations using the IXPEOBSSIM package. We consider minimal knowledge about the actual physical process responsible for the polarized emission from the accreting pulsar and assume that the observed phase-dependent polarization angle can be described by the rotating vector model. Using the unbinned technique, the detector’s modulation factor, and the polarization information alone, we found that both the rotating vector model and the underlying spectro-polarimetry model can reconstruct equally well the geometric configuration angles of the accreting pulsar. However, the measured polarization fraction becomes biased with respect to the underlying model unless the energy dispersion and effective area of the detector are also taken into account. To this end, we present an energy-dispersed likelihood estimator that is proved to be unbiased. For different analyses, we obtain posterior distributions from multiple IXPEOBSSIM realizations and show that the unbinned technique yields \r\n smaller error bars than the binned technique. We also discuss alternative sources, such as magnetars, in which the unbinned technique and the rotating vector model might be applied." article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Denis full_name: González-Caniulef, Denis last_name: González-Caniulef - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Jeremy full_name: Heyl, Jeremy last_name: Heyl citation: ama: González-Caniulef D, Caiazzo I, Heyl J.

We present here the first Imaging X-ray Polarimetry Explorer observation of the magnetar 1RXS J170849.0-400910, jointly analyzed with a new Swift observation and archival NICER data. The total (energy- and phase-integrated) emission in the 2–8 keV energy range is linerarly polarized, at a ∼35% level. The phase-averaged polarization signal shows a marked increase with energy, ranging from ∼20% at 2–3 keV up to ∼80% at 6–8 keV, while the polarization angle remains constant. This indicates that radiation is mostly polarized in a single direction. The spectrum is well reproduced by a combination of either two thermal (blackbody) components or a blackbody and a power law. Both the polarization degree and angle also show a variation with the spin phase, and the former is almost anticorrelated with the source counts in the 2–8 and 2–4 keV bands. We discuss the possible implications and interpretations, based on a joint analysis of the spectral, polarization, and pulsation properties of the source. A scenario in which the surface temperature is not homogeneous, with a hotter cap covered by a gaseous atmosphere and a warmer region in a condensed state, provides a satisfactory description of both the phase- and energy-dependent spectro-polarimetric data. The (comparatively) small size of the two emitting regions, required to explain the observed pulsations, does not allow to reach a robust conclusion about the presence of vacuum birefringence effects. article_number: L27 article_processing_charge: No article_type: original arxiv: 1 author: -

We found that in alkaline, drying conditions in bulk and at heated air‐water interfaces, 2′,3′‐cyclic nucleotides oligomerised without additional catalyst, forming up to 10‐mers within a day. The oligomerisation proceeded at a pH range of 7–12, at temperatures between 40–80 °C and was marginally enhanced by K+ ions. Among the canonical ribonucleotides, cGMP oligomerised most efficiently. Quantification was performed using HPLC coupled to ESI‐TOF by fitting the isotope distribution to the mass spectra. Our study suggests a oligomerisation mechanism where cGMP aids the incorporation of the relatively unreactive nucleotides C, A and U. The 2′,3′‐cyclic ribonucleotides are byproducts of prebiotic phosphorylation, nucleotide syntheses and RNA hydrolysis, indicating direct recycling pathways. The simple reaction condition offers a plausible entry point for RNA to the evolution of life on early Earth. acknowledgement: We would like to thank Ulrich Gerland, Tobias Göppel, Joachim Rosenberger and Bernhard Altaner for their helpful remarks and discussions; Thomas Matreux, Alexandra Kühnlein, Noël Yeh Martin and Maximilian Weingart for comments on the manuscript.

For finite matrix size we calculate the moments in terms of hypergeometric functions of matrix argument and give explicit integral representations highlighting the duality between the moment and the matrix size as well as the duality between the orthogonal and symplectic cases. Asymptotic expansions in strong and weak non-unitarity regimes are obtained. Using the connection to matrix hypergeometric functions, we establish limit theorems for the log-modulus of the characteristic polynomial evaluated on the unit circle. acknowledgement: N.S. gratefully acknowledges financial support of the Royal Society, grant URF/R1/180707.
