Several photometric studies have shown the presence of young population in the disk of the galaxy with an old metal poor halo. Since ultra-violet radiation can probe the recent star forming activities in a galaxy, UVIT observations in four different filters (F148W, F169M, N245M, N263M) are performed for this galaxy. We performed aperture photometry to estimate the magnitudes in each filter and created UVIT color-magnitude diagrams (CMD) with the identified sources. We have fitted isochrones, generated from Flexible Stellar Population Synthesis (FSPS) model, in the observed CMD to estimate different parameters of the identified sources. With the better spatial resolution of UVIT than that of GALEX, we have identified several star forming regions near the center of the galaxy also. |
