Abstract Type : Poster Abstract Category : Galaxies and Cosmology Abstract : NGC 4258 (M106) is a Seyfert 1.9 SAB(s)bc type galaxy, distinguished by its striking dual spiral arms extending in a north-south orientation. Multi-wavelength observations have revealed two additional “anomalous” arms that begin aligned in the north-south direction but curve northeast and southwest, displaying bifurcations in both X-ray/radio wavelengths. In this work, we use multi-wavelength data to understand the impact of AGN feedback on the star formation and ISM in the galaxy. We use AstroSat/UVIT observations to estimate the star-formation rates and stellar ages of the star-forming regions across the galaxy. Furthermore, we employ the JWST IR data to investigate the spatial distribution and kinematics of molecular/ionised gases and PAHs in the galaxy. In this poster, we present the results from a comprehensive multi-wavelength assessment of the dynamic interplay between star formation and AGN in NGC 4258. |
