Multicolour broadband study of a lenticular galaxy : NGC 4753

Abstract

Based on VBT observations, we report multicolour broadband study of a lenticular galaxy, NGC 4753 with prominent dust lanes. The extinction curve derived for NGC 4753 is similar to the Galactic extinction curve. The dust mass estimated from optical extinction is 1.51 x 105 M? and from the far infrared fluxes observed with Infrared Astronomical Satellite (IRAS) is 3.46 x 105 M?. The dust observed within NGC 4753 can be argued to be internal in origin.
