SMA Observations of the Archetypal Compact Steep-spectrum Radio Source 3C 303.1

Rushikesh Bhutkar, Mark Gurwell, Christopher O'Dea +5

AGN (active galactic nuclei) feedback plays a crucial role in shaping galaxy evolution. Numerical simulations show that the kinetic energy transfer efficiency from radio jets to in…

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…

Powerful yet lonely: Is 3C 297 a high-redshift fossil group?

Valentina Missaglia, Juan P. Madrid, Mischa Schirmer +8

The environment of the high-redshift (z=1.408), powerful radio-loud galaxy 3C 297 has several distinctive features of a galaxy cluster. Among them, a characteristic halo of hot gas…

The long-term broad-line responsivity in MKN 110

D. Homan, A. Lawrence, M. Ward +7

We examine the long-term history of the optical spectrum of the extremely variable Active Galactic Nucleus (AGN) MKN 110. By combining various archival data with new data, we cover…

The cavity of 3CR 196.1: H emission spatially associated with an X-ray cavity

A. Jimenez-Gallardo, E. Sani, F. Ricci +20

We present a multifrequency analysis of the radio galaxy 3CR 196.1 (), associated with the brightest galaxy of the cool core cluster CIZAJ0815.4-0303. This nearby radio…

The Bolometric Luminosity Correction of Radio-Quiet and Radio-Loud Quasars at 1<z<2

Mojegan Azadi, Belinda Wilkes, Joanna Kuraszkiewicz +2

To understand the impact of active galactic nuclei (AGN) on their host galaxies and large scale environment it is crucial to determine their total radiative power across all wavele…
