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.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by/4.0/","fulldoi":"https://doi.org/10.3847/2041-8213/acffc4","publication_identifier":{"eissn":["2041-8213"],"issn":["2041-8205"]},"external_id":{"arxiv":["2310.03204"]}},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"08","intvolume":"       953","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"publication":"The Astrophysical Journal Letters","arxiv":1,"fulldoi":"https://doi.org/10.3847/2041-8213/ace7cf","external_id":{"arxiv":["2303.13573"]},"publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"main_file_link":[{"url":"https://doi.org/10.3847/2041-8213/ace7cf","open_access":"1"}],"scopus_import":"1","abstract":[{"lang":"eng","text":"We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. 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."}],"type":"journal_article","article_processing_charge":"No","article_number":"L1","date_created":"2024-03-26T09:47:22Z","publisher":"American Astronomical Society","issue":"1","date_updated":"2024-04-02T07:01:46Z","status":"public","citation":{"ieee":"K.

are the most strongly magnetized neutron stars, and one of the most promising targets for X-ray polarimetric measurements. 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.","lang":"eng"}],"type":"journal_article","main_file_link":[{"url":"https://doi.org/10.3847/2041-8213/acb703","open_access":"1"}],"scopus_import":"1","publication":"The Astrophysical Journal Letters","intvolume":"       944","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"arxiv":1,"day":"15","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"doi":"10.3847/2041-8213/acc103","month":"03","article_type":"original","title":"Observable signatures of stellar-mass black holes in active galactic nuclei","language":[{"iso":"eng"}],"_id":"17507","author":[{"first_name":"Hiromichi","full_name":"Tagawa, Hiromichi","last_name":"Tagawa"},{"last_name":"Kimura","first_name":"Shigeo S.","full_name":"Kimura, Shigeo S."},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","full_name":"Haiman, Zoltán","last_name":"Haiman"},{"last_name":"Perna","first_name":"Rosalba","full_name":"Perna, Rosalba"},{"last_name":"Bartos","full_name":"Bartos, Imre","first_name":"Imre"}],"date_published":"2023-03-21T00:00:00Z","date_updated":"2024-09-10T10:52:04Z","issue":"1","citation":{"ieee":"H.

However, clear evidence for AGN disk-embedded BHs is currently lacking. Here, as possible electromagnetic signatures of these BHs, we investigate breakout emission from shocks emerging around Blandford–Znajek jets launched from accreting BHs in AGN disks. We assume that most of the highly super-Eddington flow reaches the BH and produces a strong jet, and the jet produces feedback that shuts off accretion and thus leads to episodic flaring. These assumptions, while poorly understood at present, yield observable consequences that can probe the presence of AGN-embedded BHs as well as the accretion process itself. They predict a breakout emission characterized by luminous thermal emission in the X-ray bands and bright broadband nonthermal emission from the infrared to the gamma-ray bands. The flare duration depends on the BH's distance r from the central supermassive BH, varying between 103–106 s for r ∼ 0.01–1 pc. This emission can be discovered by current and future infrared, optical, and X-ray wide-field surveys and monitoring campaigns of nearby AGNs."}],"fulldoi":"https://doi.org/10.3847/2041-8213/acc103","publication_identifier":{"issn":["2041-8205","2041-8213"]}},{"day":"13","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication":"The Astrophysical Journal Letters","intvolume":"       945","fulldoi":"https://doi.org/10.3847/2041-8213/acbfb8","publication_identifier":{"issn":["2041-8205","2041-8213"]},"type":"journal_article","abstract":[{"text":"The astrophysical origin of over 90 compact binary mergers discovered by the LIGO and Virgo gravitational wave observatories is an open question. While the unusual mass and spin of some of the discovered objects constrain progenitor scenarios, the observed mergers are consistent with multiple interpretations. A promising approach to solve this question is to consider the observed distributions of binary properties and compare them to expectations from different origin scenarios. Here we describe a new hierarchical population analysis framework to assess the relative contribution of different formation channels simultaneously. For this study we considered binary formation in active galactic nucleus (AGN) disks along with phenomenological models, but the same framework can be extended to other models. We find that high-mass and high-mass-ratio binaries appear more likely to have an AGN origin compared to having the same origin as lower-mass events.

The gravitational-wave emission from such an event is expected to be detectable by the future Laser Interferometer Space Antenna (LISA) and other millihertz detectors. It was recently suggested that the EMRI rate in SMBH binary systems is orders of magnitude higher than the EMRI rate around a single SMBH with the same total mass. Here we show that this high rate can produce thousands of SMBH–BH sources at a redshift of unity. We predict that LISA may detect a few hundred of these EMRIs with signal-to-noise ratio above S/N ≥8 within a 4 yr mission lifetime. The remaining subthreshold sources will contribute to a large confusion noise, which is approximately an order of magnitude above LISA’s sensitivity level.

Our JWST spectra cover the quasars' emission between rest frame ∼ 4100 and 5100 Å. The profiles of these quasars' broad Hβ emission lines span a FWHM from 3000 to 6000 km s−1. The Hβ-based virial black hole (BH) masses, ranging from 0.6 to 2.1 billion solar masses, are generally consistent with their MgII-based BH masses. The new measurements based on the more reliable Hβ tracer thus confirm the existence of billion solar-mass BHs in the reionization epoch. In the observed [OIII] λλ4960,5008 doublets of these luminous quasars, broad components are more common than narrow core components (≤ 1200 km s−1), and only one quasar shows stronger narrow components than broad. Two quasars exhibit significantly broad and blueshifted [OIII] emission, thought to trace galactic-scale outflows, with median velocities of −610 km s−1 and −1430 km s−1 relative to the [CII] 158μm line. All eight quasars show strong optical FeII emission, and follow the Eigenvector 1 relations defined by low-redshift quasars.

present the first results from the JWST ASPIRE program (A SPectroscopic survey of biased halos In the Reionization Era). This program represents an imaging and spectroscopic survey of 25 reionization-era quasars and their environments by utilizing the unprecedented capabilities of NIRCam Wide Field Slitless Spectroscopy (WFSS) mode. ASPIRE will deliver the largest (∼280 arcmin^2) galaxy redshift survey at 3-4 μm among JWST Cycle-1 programs and provide extensive legacy values for studying the formation of the earliest supermassive black holes (SMBHs), the assembly of galaxies, early metal enrichment, and cosmic reionization. In this first ASPIRE paper, we report the discovery of a filamentary structure traced by the luminous quasar J0305-3150 and ten [OIII] emitters at z=6.6. This structure has a 3D galaxy overdensity of δgal=12.6 over 637 cMpc3, one of the most overdense structures known in the early universe, and could eventually evolve into a massive galaxy cluster. Together with existing VLT/MUSE and ALMA observations of this field, our JWST observations reveal that J0305-3150 traces a complex environment where both UV-bright and dusty galaxies are present, and indicate that the early evolution of galaxies around the quasar is not simultaneous. In addition, we discovered 31 [OIII] emitters in this field at other redshifts, 5.3<z<6.7, with half of them situated at z∼5.4 and z∼6.2. This indicates that star-forming galaxies, such as [OIII] emitters, are generally clustered at high redshifts. These discoveries demonstrate the unparalleled redshift survey capabilities of NIRCam WFSS and the potential of the full ASPIRE survey dataset."}],"intvolume":"       951","publication":"The

Radiation from such objects is expected to be highly polarized due to birefringence of plasma and vacuum associated with propagation of photons in the presence of the strong magnetic field. Here we present results of the observations of Cen X-3 performed with the Imaging X-ray Polarimetry Explorer. The source exhibited significant flux variability and was observed in two states different by a factor of ∼20 in flux. In the low-luminosity state, no significant polarization was found in either pulse phase-averaged (with a 3σ upper limit of 12%) or phase-resolved (the 3σ upper limits are 20%–30%) data. In the bright state, the polarization degree of 5.8% ± 0.3% and polarization angle of 49fdg6 ± 1fdg5 with a significance of about 20σ were measured from the spectropolarimetric analysis of the phase-averaged data. The phase-resolved analysis showed a significant anticorrelation between the flux and the polarization degree, as well as strong variations of the polarization angle. The fit with the rotating vector model indicates a position angle of the pulsar spin axis of about 49° and a magnetic obliquity of 17°. The detected relatively low polarization can be explained if the upper layers of the neutron star surface are overheated by the accreted matter and the conversion of the polarization modes occurs within the transition region between the upper hot layer and a cooler underlying atmosphere. A fraction of polarization signal can also be produced by reflection of radiation from the neutron star surface and the accretion curtain.","lang":"eng"}],"fulldoi":"https://doi.org/10.3847/2041-8213/aca486","external_id":{"arxiv":["2209.02447"]},"publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"arxiv":1,"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"intvolume":"       941","publication":"The Astrophysical Journal Letters","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"12"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"30","arxiv":1,"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":"       931","publication":"The Astrophysical Journal Letters","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.3847/2041-8213/ac6585","open_access":"1"}],"type":"journal_article","abstract":[{"lang":"eng","text":"The maximum mass of a star that can produce a white dwarf (WD) is an important astrophysical quantity. One of the best approaches to establishing this limit is to search for WDs in young star clusters in which only massive stars have had time to evolve and where the mass of the progenitor can be established from the cooling time of the WD together with the age of the cluster. Searches in young Milky Way clusters have not thus far yielded WD members more massive than about 1.1 M⊙, well below the Chandrasekhar mass of 1.38 M⊙, nor progenitors with masses in excess of about 6 M⊙. However, the hunt for potentially massive WDs that escaped their cluster environs is yielding interesting candidates. To expand the cluster sample further, we used HST to survey four young and massive star clusters in the Magellanic Clouds for bright WDs that could have evolved from stars as massive as 10 M⊙. We located five potential WD candidates in the oldest of the four clusters examined, the first extragalactic single WDs thus far discovered. As these hot WDs are very faint at optical wavelengths, final confirmation will likely have to await spectroscopy with 30 m class telescopes."}],"external_id":{"arxiv":["2203.11264"]},"fulldoi":"https://doi.org/10.3847/2041-8213/ac6585","publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"publisher":"American Astronomical Society","article_processing_charge":"No","article_number":"L20","date_created":"2024-03-26T10:28:48Z","_id":"15210","author":[{"last_name":"Richer","full_name":"Richer, Harvey B.","first_name":"Harvey B."},{"last_name":"Cohen","full_name":"Cohen, Roger E.","first_name":"Roger E."},{"last_name":"Heyl","full_name":"Heyl, Jeremy","first_name":"Jeremy"},{"last_name":"Kalirai","full_name":"Kalirai, Jason","first_name":"Jason"},{"full_name":"Caiazzo, Ilaria","first_name":"Ilaria","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","orcid":"0000-0002-4770-5388","last_name":"Caiazzo"},{"last_name":"Correnti","first_name":"Matteo","full_name":"Correnti, Matteo"},{"last_name":"Cummings","first_name":"Jeffrey","full_name":"Cummings, Jeffrey"},{"full_name":"Goudfrooij, Paul","first_name":"Paul","last_name":"Goudfrooij"},{"last_name":"Hansen","full_name":"Hansen, Bradley M.

However, core-collapse supernovae simulations to date have focused almost exclusively on the evolution of single stars. We present a systematic simulation study of single and binary-stripped stars with the same initial mass as candidates for core-collapse supernovae (11–21 M⊙). Generally, we find that binary-stripped stars core tend to have a smaller compactness parameter, with a more prominent, deeper silicon/oxygen interface, and explode preferentially to the corresponding single stars of the same initial mass. Such a dichotomy of behavior between these two modes of evolution would have important implications for supernovae statistics, including the final neutron star masses, explosion energies, and nucleosynthetic yields. Binary-stripped remnants are also well poised to populate the possible mass gap between the heaviest neutron stars and the lightest black holes. Our work presents an improvement along two fronts, as we self-consistently account for the pre-collapse stellar evolution and the subsequent explosion outcome. Even so, our results emphasize the need for more detailed stellar evolutionary models to capture the sensitive nature of explosion outcome.","lang":"eng"}],"type":"journal_article","intvolume":"       916","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"publication":"The Astrophysical Journal Letters","arxiv":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"23"},{"publication":"The Astrophysical Journal Letters","intvolume":"       907","day":"21","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publisher":"American Astronomical Society","article_number":"L20","date_created":"2024-09-05T12:27:07Z","article_processing_charge":"No","type":"journal_article","abstract":[{"lang":"eng","text":"The astrophysical origin of gravitational wave transients is a timely open question in the wake of discoveries by the Laser Interferometer Gravitational-Wave Observatory (LIGO)/Virgo. 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."}],"scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3847/2041-8213/abd4d3"}],"publication_identifier":{"issn":["2041-8205","2041-8213"]},"fulldoi":"https://doi.org/10.3847/2041-8213/abd4d3","doi":"10.3847/2041-8213/abd4d3","month":"01","language":[{"iso":"eng"}],"article_type":"original","title":"Eccentric black hole mergers in active galactic nuclei","date_published":"2021-01-21T00:00:00Z","_id":"17583","author":[{"last_name":"Tagawa","first_name":"Hiromichi","full_name":"Tagawa, Hiromichi"},{"full_name":"Kocsis, Bence","first_name":"Bence","last_name":"Kocsis"},{"last_name":"Haiman","full_name":"Haiman, Zoltán","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"first_name":"Imre","full_name":"Bartos, Imre","last_name":"Bartos"},{"last_name":"Omukai","full_name":"Omukai, Kazuyuki","first_name":"Kazuyuki"},{"first_name":"Johan","full_name":"Samsing, Johan","last_name":"Samsing"}],"citation":{"short":"H.

The primary and secondary BH are both inferred to fall inside the pair-instability (PI) mass gap. Here we propose that the formation of such binaries is possible through gas accretion onto the BH remnants of Population III (Pop~III) stars born in high-redshift (z>10) minihalos. Once the parent halo has grown to the atomic-cooling limit, even brief episodes of gas accretion in the dense central regions of the halo can increase the masses of Pop~III remnant BHs above the PI limit. Starting with a BBH with an initial mass of O(100) M⊙ we find that it would only need to spend about 100~Myr in the inner few pc of an atomic-cooling halo to accrete about 50~M⊙ of material and resemble a system similar to GW190521. The dynamical friction timescale for the binary to sink to the dense inner region of its parent halo is comparable or shorter than the accretion timescale required to increase their mass above the PI limit. Once in the core of the halo, the binary can enter a phase of hyper-Eddington accretion, where it would only take a few thousand years to exceed the PI limit through accretion. Even more massive BBHs could form through this channel, and be detectable by detectors with improved low-frequency sensitivity. Single Pop~III BH remnants would also grow through accretion and could later form binaries dynamically. As little as a few percent of Pop~III BH remnants may be sufficient to match the rate of massive BBH mergers inferred from GW190521 of 0.13+0.3−0.11Gpc−3yr−1."}],"scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.3847/2041-8213/abc253","open_access":"1"}],"publication_identifier":{"issn":["2041-8205","2041-8213"]},"fulldoi":"https://doi.org/10.3847/2041-8213/abc253","publication":"The Astrophysical Journal Letters","intvolume":"       903","day":"02","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345"},{"fulldoi":"https://doi.org/10.3847/2041-8213/ab745d","external_id":{"arxiv":["1911.11142"]},"publication_identifier":{"issn":["2041-8205","2041-8213"]},"scopus_import":"1","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1911.11142"}],"type":"journal_article","abstract":[{"text":"Despite the rapidly growing number of stellar-mass binary black hole mergers discovered through gravitational waves, the origin of these binaries is still not known. In galactic centers, black holes can be brought to each others' proximity by dynamical processes, resulting in mergers. It is also possible that black holes formed in previous mergers encounter new black holes, resulting in so-called hierarchical mergers. Hierarchical events carry signatures such as higher-than-usual black hole mass and spin. Here we show that the recently reported gravitational-wave candidate, GW170817A, could be the result of such a hierarchical merger. In particular, its chirp mass ∼40 M⊙ and effective spin of χeff ∼ 0.5 are the typically expected values from hierarchical mergers within the disks of active galactic nuclei. We find that the reconstructed parameters of GW170817A strongly favor a hierarchical merger origin over having been produced by an isolated binary origin (with an odds ratio of > 10^3).","lang":"eng"}],"article_processing_charge":"No","article_number":"L20","date_created":"2024-09-05T13:13:33Z","publisher":"American Astronomical Society","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","day":"18","intvolume":"       890","publication":"The Astrophysical Journal Letters","arxiv":1,"publication_status":"published","year":"2020","extern":"1","oa_version":"Preprint","volume":890,"oa":1,"quality_controlled":"1","date_updated":"2024-09-23T14:04:29Z","issue":"2","citation":{"ieee":"V.
