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…
When Jets Don't Quench: Near-Infrared H in Star Forming Low-Excitation Radio Galaxies
Swetha Sankar, Andreea O. Petric, Debora Pelliccia +11
We present new Gemini/GNIRS near-infrared spectroscopic observations of eight low-redshift () blue low-excitation radio galaxies (BLERGs), a rare subset ( of l…
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…
First results from the JWST Early Release Science Program Q3D: The Fast Outflow in a Red Quasar at z=0.44
Weizhe Liu, Sylvain Veilleux, Swetha Sankar +26
Quasar feedback may play a key role in the evolution of massive galaxies. The dust-reddened quasar, F2M110648.35480712 at is one of the few cases at its redshift th…
