The Close AGN Reference Survey (CARS): A comparison between sub-mm and optical AGN diagnostic diagrams

Jacob S. Elford, Timothy A. Davis, Ilaria Ruffa +9

The relation suggests that there is a tight connection between dense gas and star formation. We use data from the Close AGN Reference Survey (CARS) to inve…

Cocoon shock, X-ray cavities and extended Inverse Compton emission in Hercules A: clues from Chandra observations

F. Ubertosi, Y. Gong, P. Nulsen +7

We present a detailed analysis of jet activity in the radio galaxy 3C348 at the center of the galaxy cluster Hercules A. We use archival Chandra data to investigate the jet-driven…

Jetted subgalactic-size radio sources in merging galaxies -- A jet redirection scenario

C. Stanghellini, M. Orienti, C. Spingola +6

Context: The long-standing question concerning jetted subgalactic-size (JSS) radio sources is whether they will evolve into large radio galaxies, die before escaping the host galax…

A VLBA-uGMRT search for candidate binary black holes: Study of six X-shaped radio galaxies with double-peaked emission lines

Biny Sebastian, Anderson Caproni, Preeti Kharb +6

Identifying methods to discover dual AGN has proven to be challenging. Several indirect tracers have been explored in the literature, including X/S-shaped radio morphologies and do…

"Beads on a String" Star Formation Tied to one of the most Powerful AGN Outbursts Observed in a Cool Core Galaxy Cluster

Osase Omoruyi, Grant R. Tremblay, Francoise Combes +19

With two central galaxies engaged in a major merger and a remarkable chain of 19 young stellar superclusters wound around them in projection, the galaxy cluster SDSS J1531+3414 ($z…

New Black Hole Spin Values for Sagittarius A* Obtained with the Outflow Method

Ruth A. Daly, Megan Donahue, Christopher P. O'Dea +3

Six archival Chandra observations are matched with eight sets of radio data and studied in the context of the outflow method to measure and study the spin properties of $\rm{Sgr ~A…
