Search and characterization of remnant radio galaxies in the XMMLSS deep field
Sushant Dutta, Veeresh Singh, C. H. Ishwara Chandra +3
The remnant phase of a radio galaxy is characterized by the cessation of AGN activity resulting in the stoppage of jets supplying plasma to radio lobes. In this paper, we present t…
