Abstract

Active galactic nuclei (AGN) release substantial energy into their surrounding environn1ent, influencing the physical properties of the host galaxy and regulating the accretion of matter onto the central 'supermassive black hole (SMBI-D.' This process is known as ?GN feedback.' While AGN feedback is consideied an essential component in simulations to reproduce several observed properties of galaxies and clusters" direct observational evidence for its immediate and long-term impact on 'star formation' (SF) in both strong- and weak-jetted systems remains sparse and often contrasting. The primary limitation arises from the lack of high-resolution observations required for spatially resolved investigations of SF down to the scale of individual stellar clusters. Ultraviolet (UV) emission is a primary and direct tracer of SF in galaxies. The 'UltraViolet Imaging Telescope' (UVIT) onboard AstroSat, launched in 2015, provides high-resolution (1.2-1.5") UV observations, enabling detailed studies of SF regions in nearby galaxies. ln this thesis, we primarily utilized high-resolution UV observations AstroSat-U\1T to e:xamine how AGN feedback affects the SF properties of the host galaxy
