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 u…
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…
