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…

The Two Component Circumgalactic Medium Emission around z~2 Radio-loud Quasars

Sanchit Sabhlok, Shelley A. Wright, Andrey Vayner +7

We present Ly, He II and C IV observations of 7 redshift ~ 2 radio-loud quasars observed using the Keck Cosmic Web Imager (KCWI) and compare it to observed radio jet emission us…

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…

Tracking Outflow using Line-Locking (TOLL). II. Large Line-Locking Web identified in Quasar J151352+085555

Chen Chen, Zhicheng He, Weimin Yi +3

Quasar outflows often consist of two clouds with velocity separations matching the doublet spacings of common UV resonance transitions, a phenomenon known as line-locking, which is…

[OIII] 5007 emissions in extremely red quasars (ERQs) are compact

Marie Wingyee Lau, Serena Perrotta, Fred Hamann +5

``Extremely red quasars'' (ERQs) are a non-radio-selected, intrinsically luminous population of quasars at cosmic noon selected by their extremely red colour from rest-frame UV to…

Accurate Systemic Redshifts and Outflow Speeds for Extremely Red Quasars (ERQs)

Jarred Gillette, Fred Hamann, Marie Wingyee Lau +1

Extremely Red Quasars (ERQs) are thought to represent a brief episode of young quasar and galactic evolution characterized by rapid outflows and obscured growth due to dusty enviro…
