Sujatha & Narayanankutty Karuppath Abstract Type : Poster Abstract Category : Stars, ISM and Galaxy Abstract : We present the results of the primary analyses of the observed diffuse UV background from a Southern low Galactic latitude region (b < 10 degree; 25 degree < l < 40 degree) using the GR6/GR7 GALEX data. The airglow emission contributes negligibly less (< 5 PU) to the observed UV backgrounds in the region while the NUV zodiacal light is about 380 - 560 PU. The median diffuse FUV and NUV backgrounds in the region are estimated to be 2770 and 2200 PU respectively, with standard deviations less than 40 PU. The observed UV backgrounds in the region are negatively correlated with IR 100 μm emission as well as the N(H) emission which are quite interesting and may be attributed to the peculiar dust distribution in the line of sight. We suspect the presence of multiple layers of dust in the line of sight resulting in such negative correlations. More detailed studies and modeling are required for a complete understanding of the dust distribution and the observed FUV and NUV emissions from the region, which we are concentrating on now. |
