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 Díaz-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…

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…

Spatially resolved dust properties over 50 kpc in a hyperluminous galaxy merger at

Román Fernández Aranda, Tanio Díaz Santos, Evanthia Hatziminaoglou +19

We present spatially resolved dust-continuum ALMA observations from rest-frame 60 to 600 m (bands 3-10) of the hyperluminous hot dust-obscured galaxy (hot DOG) WISE…

Overdensity of Lyman-Break Galaxy Candidates Around Hot Dust-Obscured Galaxies

Dejene Zewdie, Roberto J. Assef, Trystan Lambert +15

Hot dust-obscured galaxies (Hot DOGs), are a family of hyper-luminous, heavily obscured quasars. A number of studies have shown that these objects reside in significantly overdense…

Powerful nuclear outflows and circumgalactic medium shocks driven by the most luminous known obscured quasar in the Universe

Andrey Vayner, Tanio Díaz-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…

Black Hole Mass and Eddington Ratio Distribution of Hot Dust-Obscured Galaxies

Guodong Li, Roberto J. Assef, Chao-Wei Tsai +8

Hot Dust-Obscured Galaxies (Hot DOGs) are a rare population of hyper-luminous infrared galaxies discovered by the WISE mission. Despite the significant obscuration of the AGN by du…

The properties of inside-out assembled galaxies at

Dejene Zewdie, Mirjana Pović, Manuel Aravena +2

In this work, we study the properties of galaxies that are showing the inside-out assembly (which we call inside-out assembled galaxies; IOAGs), with the main aim to understand bet…

Accretion rate in AGN and X-ray-to-optical flux ratio at z 0.2

Asrate Gaulle, Mirjana Pović, Dejene Zewdie

We explored a sample of 545 local galaxies using data from the 3XMM-DR7 and SDSS-DR8 surveys. We carried out all analyses up to z\,\,0.2, and we studied the relation between…
