[64.17] GALEX Diffuse UV Background

R. C. Henry, L. Bianchi (JHU), J. Murthy, P. Shalima (IIA)

We report preliminary investigation of the character of the diffuse ultraviolet background radiation as it is detected using the two ultraviolet cameras on GALEX. The bulk of the signal in most GALEX images is diffuse background, not point sources or galaxies. This diffuse radiation originates in a plethora of sources, including airglow/geophysical effects, zodiacal light (in the longer-wavelength of the two GALEX cameras), ultraviolet starlight scattered from interstellar dust, and additional radiation of unclear origin. Our Guest Investigator programs are just beginning: in this poster paper we concentrate on our examination of the publicly available Deep Imaging Survey targets. Our Guest Investigator targets have been carefully chosen to allow testing of the idea that part of the detected signal may be due to redshifted recombination radiation from the intergalactic medium.
