Ultraviolet Studies of the Large Magellanic Cloud using GALEX observations

The Large Magellanic Cloud (LMC) is one of our nearest neighbor galaxies at a distance of ~50 Kpc. The LMC has been the center of many photometric surveys at different wavelength bands as it is characterized by a number of environmental differences relative to the Milky Way. Recently, Galaxy Evolution Explorer (GALEX) has imaged the Magellanic Clouds in near-ultraviolet (NUV: 1771 - 2831 Ang) and far-ultraviolet (FUV: 1344 - 1786 Ang) wavelength bands. We have cross-matched the GALEX sources to the infrared (IR) source catalog and then used an IR colour cut method to select the UV point sources in the GALEX source catalog. We estimated the spectral types of the stars and extinctions using a least square technique, based on spectral energy distribution analysis. We have also estimated the UV diffuse emission and diffuse fraction for the GALEX images in the LMC. In this presentation, I will talk about the distribution of UV emission and classification of the UV sources in the LMC using GALEX observations.
