摘要：Summary We have studied the diffuse UV emission from Lockman Hole using 23 Deep Imaging Surveys (DIS) of GALEX mission in order to quantify different components of diffuse UV radiation and search for extragalactic emission. The region is important due to the presence of minimal amount of gas and dust and the GALEX images cover more than 10 square degrees in the region. The UV emissions in the region are compared with Infrared 100μm emission and we find a slight anti-correlation between UV and IR flux, which we attribute to the presence of extragalactic contribution in the diffuse background. Using the positional details of Spitzer – SERVS and SWIRE surveys, the contribution of extragalactic light was extracted as 192photonscm−2 sr−1 s−1 Å−1 in FUV and as 201photonscm−2 sr−1 s−1 Å−1 in NUV with the AB magnitude range of 17–27.
