A cosmic collision in the making: JWST/NIRISS reveals a merging and maturing protocluster core at z~3 around a red quasar
C. Bertemes, D. Wylezalek, G. Noirot +10
We report the discovery of ``The Step'', a dense protocluster at z=3 revealed by JWST/NIRISS Wide-Field Slitless Spectroscopy (WFSS) of the field around the luminous quasar and sta…
Scattering from Dusty Outflows in Hot Dust-Obscured Galaxies with Blue Excess Emission
R. J. Assef, M. Stalevski, F. E. Bauer +15
(Context) Hot Dust-Obscured Galaxies (Hot DOGs) are a population of hyper-luminous quasars heavily obscured by dust and gas. While most have rest UV/optical SEDs dominated by their…
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…
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…
Probing the Physics of Dusty Outflows through Complex Organic Molecules in the Early Universe
Andrey Vayner, Tanio DÃaz-Santos, Carl D. Ferkinhoff +22
Galaxy-scale outflows are of critical importance for galaxy formation and evolution. Dust grains are the main sites for the formation of molecules needed for star formation but are…
