We present a multi-wavelength correlation study of diffuse ultraviolet radiation using GALEX observations towards the Aquila Rift. Apart from airglow and zodiacal emissions, we find a diffuse background of 1300 - 3700 \photu\ in the far-ultraviolet (

We have used Spitzer observations of galaxies in the ELAIS-N1 region centered at 16h10m01s, +54◦30′36″ to extend the effective sensitivity of GALEX UV observations of the same region. Spitzer is more sensitive to external galaxies than GALEX an

We present an analysis of the diffuse ultraviolet (UV) background in a low latitude region near the Aquila Rift based on observations made by the Galaxy Evolution Explorer (GALEX). The UV background is at a level of about 2000 ph cm^-2 s^-1 sr^-1 \AA

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 du

We report here the results of the study of extragalactic radiation using number counts of galaxies at high galactic latitudes. For this study nine G A L E X DIS targets around ELAISN1 in the North Pole. The overlapped regions of two missions cover an

Using the GALEX ultraviolet imagers we have observed a region of nebulosity first identified as starlight scattered by interstellar dust by Sandage (1976). Apart from airglow and zodiacal emission, we have found a diffuse UV background of between 500

We have used FUSE and Voyager observations of dust-scattered starlight in the neighborhood of the Coalsack Nebula to derive the optical constants of the dust grains. The albedo is consistent with a value of 0.28 ± 0.04, and the phase function asymme

We have studied the variation of diffuse ultraviolet (UV) radiation in the northern part of the Orion constellation using a set of eight areas of the GALEX All-Sky Imaging Survey in the far and near UV. Different components of diffuse UV radiation, l

We have derived the albedo ($a$) and phase function asymmetry factor ($g$) of interstellar dust grains at 1100 \AA ~ using archival {\it Voyager} observations of diffuse radiation in Ophiuchus. We have found that the grains are highly forward scatter

We present the results of an extensive numerical study on the phenomenon of stochastic resonance in a bimodal cubic map. Both Gaussian random noise as well as deterministic chaos are used as input to drive the system between the basins. Our main resu
