Euclid: Discovery of 31 new quasars at
D. Yang, J. F. Hennawi, F. Guarneri +211
We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…
A 6.2 Quasar on the Local M- Relation Quenching Its Host Galaxy from the Aether Survey
Weizhe Liu, Emanuele Paolo Farina, Xiaohui Fan +19
We report JWST/NIRSpec integral field unit (IFU) observations of the quasar J15124422 at from the Aether survey. At 900 Myr after the Big Bang, this object al…
Detection of an Extended Ly Halo around a Broad Absorption Line Quasar with the Keck Cosmic Web Imager
Raymond P. Remigio, Aaron J. Barth, Feige Wang +6
We present the first results from a program searching for extended Ly halos around high redshift () quasars using the red channel of the Keck Cosmic Web Imager…
AGN STORM 2. XII. Ground-Based Optical Photometry and Lag Measurements of Mrk 817
John W. Montano, Aaron J. Barth, Keith Horne +40
We present the ground-based imaging campaign and light curves of Markarian 817 as part of the multiwavelength monitoring program AGN STORM\,2. Observations were carried out over 1.…
Can BLR line profile shape improve single-epoch black hole mass estimates?
Lizvette Villafaña, Tommaso Treu, Shu Wang +7
The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…
A Phenomenological Study of the Accretion Disk in the Super-Eddington AGN I Zw 1
Farin Drewes, Roberta Vieliute, Juan V. Hernández Santisteban +11
The structure of the accretion disk in AGN is still an unsolved question, especially how it may change with Eddington ratio. Here we examine the accretion disk in the super-Eddingt…
