Kinematic Stratification in Extremely Red Quasars Revealed by JWST

Jack M. M. Neustadt, Nadia L. Zakamska, Yu-Ching Chen +7

We analyze the spectra of the central nuclei of extremely red quasars (ERQs) observed as part of the JWST ERS Q3D program. We focus on the complex kinematic structures of the promi…

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.…

JWST IFU observations uncover host galaxy continua in extremely red and obscured quasars

Yu-Ching Chen, Nadia L. Zakamska, Andrey Vayner +9

Uncovering bright quasars' host galaxies at cosmic noon is challenging because of the high contrast between the quasar and its host and redshifted light, making them primarily visi…

Using AGN lightcurves to map accretion disc temperature fluctuations

J. M. M. Neustadt, C. S. Kochanek

We introduce a new model for understanding AGN continuum variability. We start from a Shakura--Sunyaev thin accretion disc with a steady-state radial temperature profile and…

An Amusing Look at the Host of the Periodic Nuclear Transient ASASSN-14ko Reveals a Second AGN

M. A. Tucker, B. J. Shappee, J. T. Hinkle +10

We present Multi-Unit Spectroscopic Explorer (MUSE) integral-field spectroscopy of ESO 253G003, which hosts a known Active Galactic Nucleus (AGN) and the periodic nuclear transi…
