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…
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…
Powerful nuclear outflows and circumgalactic medium shocks driven by the most luminous known obscured quasar in the Universe
Andrey Vayner, Tanio DÃaz-Santos, Peter R. M. Eisenhardt +18
We report integral field spectroscopy observations with the Near-Infrared Spectrograph on board JWST targeting the 60 kpc environment surrounding the most luminous obscured quasar…
A Massive Gas Outflow Outside the Line-of-Sight: Imaging Polarimetry of the Blue Excess Hot Dust Obscured Galaxy W0204-0506
Roberto J. Assef, Marko Stalevski, Lee Armus +18
(Aims) Hot Dust Obscured Galaxies (Hot DOGs) are a population of hyper-luminous, heavily obscured quasars. Although nuclear obscurations close to Compton-thick are typical, a fract…
Resolving the black hole sphere of influence in a hyper-luminous obscured quasar at redshift 4.6
Mai Liao, Roberto J. Assef, Chao-Wei Tsai +17
Supermassive black holes (SMBHs) imprint gravitational signatures on the matter within their sphere of influence (SoI). Nuclear gas dynamics can hence be used to accurately measure…
Searching for Low-Redshift Hot Dust-Obscured Galaxies
Guodong Li, Jingwen Wu, Chao-Wei Tsai +13
Hot Dust-Obscured Galaxies (Hot DOGs), discovered by the "W1W2 dropout" selection at high redshifts ( 2-4), are a rare population of hyper-luminous obscured quasars. Their n…
