Abstract

We present an analysis of the ultra-violet (UV) observations of two Seyfert type active galactic nuclei (AGN), namely NGC 4051 and NGC 4151. These observations aimed at studying the star formation in the hosts of these AGN were carried out with the ultra-violet imaging telescope on board AstroSat in far-UV. A total of 193 and 328 star-forming regions (SF) were identified using SExtractor in NGC 4051 and NGC 4151, respectively. Using aperture photometry of the identified SF regions, we estimated the star formation rates (SFRs). We found NGC 4051 to have the lowest SFR with a median value of 3.16 × 10−5 M⊙ yr−1 while for NGC 4151, we found a median SFR of 0.012 M⊙ yr−1.
