Extragalactic Background Light (EBL) studies have revealed a significant discrepancy between direct measurements -- via instruments measuring "bare" sky from which Zodiacal and Galactic light models are subtracted -- and measurements of the Integrated Galaxy Light (IGL). This discrepancy could lie in either method, whether it be an incomplete Zodiacal model or missed faint galaxies in the IGL calculations. It has been proposed that the discrepancy is due to deep galaxy surveys, such as those with the Hubble ...

Abstract Project SKYSURF aims to account for the difference between observed integrated background light levels and those expected from galaxy-count ... integrated background light from galaxies. Since the existing SKYSURF analysis cannot constrain bright galaxy counts well, we ... the bright object number density by cross-matching SKYSURF pointings with objects in the Sloan Digital Sky ... level of incompleteness in SDSS and suggesting that SKYSURF pointings are in general not substantially biased toward ...
