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, F2M110648.35 $+$ 480712 at $z = 0.4352$ is one of the few cases at its redshift th…

MALS discovery of a rare HI 21-cm absorber at $z \sim 1.35$ : origin of the absorbing gas in powerful AGN

P. P. Deka, N. Gupta, H. W. Chen +14

We report a new, rare detection of HI 21-cm absorption associated with a quasar (only six known at $1 < z < 2$ ) here towards J2339-5523 at $z_{e m}$ = 1.3531, discovered through the Mee…
