First Results from the JWST Early Release Science Program Q3D: AGN Photoionization and Shock Ionization in a Red Quasar at

Swetha Sankar, Nadia L. Zakamska, David S. N. Rupke +12

Red quasars, often associated with powerful [O III] outflows on both galactic and circumgalactic scales, may play a pivotal role in galaxy evolution and black hole feedback. In thi…

Varstrometry for Off-nucleus and Dual Subkiloparsec AGN (VODKA): Three Quadruply Lensed Quasars at Cosmic Noon in HST and JWST

Mingrui Liu, Yu-Ching Chen, Nadia L. Zakamska +7

We present results from imaging observations of three quadruply lensed quasars by Hubble Space Telescope (HST) and James Webb Space Telescope (JWST) at redshifts , 2.975…

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…

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…

VODKA: Complex molecular gas dynamics in a kpc-separation z=2.17 dual quasar with ALMA

Yuzo Ishikawa, Nadia L. Zakamska, Yu-Ching Chen +6

In galaxy mergers, dual quasars - two actively accreting supermassive black holes (SMBHs) - provide a unique opportunity to study the interplay between galaxy dynamics and quasar a…
