AGN activity and IGM heating in fossil cluster RX J1416.4+2315
H. Miraghaei, H. G. Khosroshahi, C. Sengupta +3
We study Active Galactic Nucleus (AGN) activity in the fossil galaxy cluster, RX J1416.4+2315. Radio observations were carried out using Giant Metrewave Radio Telescope (GMRT) at t…
Kernel regression estimates of time delays between gravitationally lensed fluxes
Sultanah AL Otaibi, Peter Tiňo, Juan C Cuevas-Tello +2
Strongly lensed variable quasars can serve as precise cosmological probes, provided that time delays between the image fluxes can be accurately measured. A number of methods have b…
New insights into the evolution of the FR I radio galaxy 3C 270 (NGC 4261) from VLA and GMRT radio observations
Konstantinos Kolokythas, Ewan O'Sullivan, Simona Giacintucci +4
We present Giant Metrewave Radio Telescope (GMRT) 240 MHz observations of the nearby luminous FR I radio source 3C 270, in the group-central elliptical NGC 4261. Combining these da…
