The SKA-VLBI Perspective on Radio-Quiet AGN
Francesca Panessa, Tao An, James Petley +21
The accretion-ejection mechanism in Active Galactic Nuclei (AGN) remains a central open problem in astrophysics, tied to the role of AGN feedback in galaxy formation and evolution.…
3C 273 Host Galaxy with Hubble Space Telescope Coronagraphy
Bin B. Ren, Kevin Fogarty, John H. Debes +6
The close-in regions of bright quasars' host galaxies have been difficult to image due to the overwhelming light from the quasars. With coronagraphic observations in visible light…
Powerful Radio-Loud Quasars are Triggered by Galaxy Mergers in the Cosmic Bright Ages
Peter Breiding, Marco Chiaberge, Erini Lambrides +14
While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) drivi…
NOEMA observations support a recoiling black hole in 3C186
G. Castignani, E. Meyer, M. Chiaberge +7
3C186 is a powerful radio loud quasar (QSO) at the center of a cool-core cluster at z=1.06. Previous studies reported evidence for a projected spatial offset of ~1'' between the is…
Lower-Luminosity Obscured AGN Host Galaxies are Not Predominantly in Major-Merging Systems at Cosmic Noon
Erini Lambrides, Marco Chiaberge, Timothy Heckman +15
For over 60 years, the scientific community has studied actively growing central super-massive black holes (active galactic nuclei -- AGN) but fundamental questions on their genesi…
Merger or Not: Accounting for Human Biases in Identifying Galactic Merger Signatures
Erini Lambrides, Duncan J. Watts, Marco Chiaberge +9
Significant galaxy mergers throughout cosmic time play a fundamental role in theories of galaxy evolution. The widespread usage of human classifiers to visually assess whether gala…
