Abstract

This paper presents a comprehensive analysis of 30 ks Chandra and 46.8 ks (13 h) 1.4 GHz GMRT radio data on the cool-core cluster RXCJ0352.9+1941 to investigate AGN activities at its core. This study confirms a pair of X-ray cavities at projected distances of about 10.30 and 20.80 kpc, respectively, on the NW and SE of the X-ray peak. GMRT L band (1.4 GHz) data revealed a bright radio source associated with the core of this cluster hosting multiple jet-like emissions. The spatial association of the X-ray cavities with the inner pair of radio jets confirms their origin due to AGN outbursts. The 1.4 GHz radio power 7.4±0.8×1039 erg s-1 is correlated with the mechanical power stored in the X-ray cavities (∼7.90×1044 erg s-1), implying that the power injected by radio jets in the ICM is sufficient enough to offset the radiative losses. The X-shaped morphology of diffuse radio emission seems to be comprised of two pairs of orthogonal radio jets, likely formed due to a spin-flip of jets due to the merger of two systems. The X-ray surface brightness analysis of the ICM in its environment revealed two non-uniform, extended spiral-like emission structures on either side of the core, pointing towards gas sloshing due to a minor merger. It might have resulted in a cold front at ∼31 arcsec (62 kpc) with a temperature jump of 1.44 keV.
