The Contribution of AGN Accretion Disks to Hydrogen Reionization
Grisha Zeltyn, Benny Trakhtenbrot
We examine the contribution of high-redshift (z>6) active galactic nuclei (AGNs) to cosmic hydrogen reionization, by tracing the growth and ionizing output of the first generation…
Black hole virial masses from single-epoch photometry: the miniJPAS test case
Jonás Chaves-Montero, Silvia Bonoli, Benny Trakhtenbrot +25
Precise measurements of black hole masses are essential to understanding the coevolution of these sources and their host galaxies. We develop a novel approach for computing black h…
Distinguishing Tidal Disruption Events from Impostors
Ann Zabludoff, Iair Arcavi, Stephanie La Massa +15
Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have opened potential new windows into the evolution and properties of otherwise dormant superm…
BAT AGN Spectroscopic Survey XXVII: Scattered X-Ray Radiation in Obscured Active Galactic Nuclei
K. K. Gupta, C. Ricci, A. Tortosa +20
Accreting supermassive black holes (SMBHs), also known as active galactic nuclei (AGN), are generally surrounded by large amounts of gas and dust. This surrounding material reproce…
The 450 days X-ray monitoring of the changing-look AGN 1ES 1927+654
C. Ricci, M. Loewenstein, E. Kara +16
1ES 1927+654 is a nearby active galactic nucleus (AGN) which underwent a changing-look event in early 2018, developing prominent broad Balmer lines which were absent in previous ob…
BAT AGN Spectroscopic Survey-XXIII. A New Mid-Infrared Diagnostic for Absorption in Active Galactic Nuclei
Ryan W. Pfeifle, Claudio Ricci, Peter G. Boorman +15
In this study, we use the SWIFT/BAT AGN sample, which has received extensive multiwavelength follow-up analysis as a result of the BAT AGN Spectroscopic Survey (BASS), to develop a…
AT 2019avd: A novel addition to the diverse population of nuclear transients
A. Malyali, A. Rau, A. Merloni +29
We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inact…
