A Transient "Changing-look'' Active Galactic Nucleus Resolved on Month Timescales from First-year Sloan Digital Sky Survey V Data
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32
We report the discovery of a new ``changing-look'' active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy…
An extended [CII] halo around a massive star-forming galaxy at z = 5.3
T. S. Lambert, A. Posses, M. Aravena +8
High-redshift observations are often biased towards massive and bright galaxies that are not necessarily representative of the full population. In order to accurately study galaxy…
The LSST era of supermassive black holes accretion-disk reverberation mapping
Andjelka B. Kovacevic, Viktor Radovic, Dragana Ilic +22
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will detect an unprecedentedly large sample of actively accreting supermassive black holes with typical accreti…
Structure and kinematics of a massive galaxy at z ~ 7
A. C. Posses, M. Aravena, J. González-López +9
Observations of the rest-frame UV emission of high-redshift galaxies suggest that the early stages of galaxy formation involve disturbed structures. Imaging the cold interstellar m…
Imaging Polarization of the Blue-Excess Hot Dust-Obscured Galaxy WISE J011601.41-050504.0
Roberto J. Assef, Franz E. Bauer, Andrew W. Blain +8
We report on VLT/FORS2 imaging polarimetry observations in the band of WISE J011601.41-050504.0 (W0116-0505), a heavily obscured hyper-luminous quasar at $z=3.173…
BASS XXV: DR2 Broad-line Based Black Hole Mass Estimates and Biases from Obscuration
Julian E. Mejıa-Restrepo, Benny Trakhtenbrot, Michael J. Koss +26
We present measurements of broad emission lines and virial estimates of supermassive black hole masses () for a large sample of ultra-hard X-ray selected active galactic nu…
