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…
Multi-messenger flare in the quasar PKS 0446+11
Y. Y. Kovalev, M. F. Aller, A. K. Erkenov +15
The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. We investigate a prominent multi-messenger flare in the quasar PKS 1424+240…
ALMA discovery of Punctum -- a highly polarized mm source in nuclear starburst galaxy NGC 4945
E. Shablovinskaia, C. Ricci, C-S. Chang +9
We report the discovery of a highly polarized millimeter (mm) continuum source in the central region of NGC 4945, identified through ALMA Band 3 observations. This starburst Seyfer…
ALMA polarimetry of radio-quiet AGNs
E. Shablovinskaia, C. Ricci, R. Paladino +10
The compact mm emission ubiquitously found in radio-quiet active galactic nuclei (RQ AGN) exhibits properties consistent with synchrotron radiation from a small region (1 lig…
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…
