![]() ![]() We expect this method to be generically applicable over a wide range of wavebands, with a potential of performing various spectral diagnostics over the panchromatic EBL. These empirically constrained UVB spectral features provide insights on the cosmic star formation history, the absorption due to neutral gas in the interstellar medium, and the potential emission from the diffuse intergalactic medium. ![]() ![]() I will show the first application with data by probing the continuum, Lyα line, and Lyman break in the cosmic UV background (UVB) up to z~2 using GALEX All Sky and Medium Imaging Surveys. For this, we developed a cross-correlation based tomographic method to recover previously lost redshift and sub-bandpass frequency information for the diffuse light in classic wide-field, broadband imaging surveys. The'' (Miller),302 ''Red Planet Blues'' (Steele),284 Red Shift (Garner), 233 Red shifts, 103,203, 433 Redshift Rendezvous (Stith), 239 Red Spot. However, one needs to resolve key spectral features in the EBL in order to extract the physics. Redshift Rendezvous, a Nebula Award nominee, is a murder mystery set aboard a space ship traveling through hyperspace, where the speed of light is ten. The extragalactic background light (EBL) provides a summary statistic of cosmological galaxy formation and encodes information from all relevant physics in a light-weighted manner. ![]()
