![]() ![]() According to NASA (opens in new tab), violet has the. 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. To understand redshift and blueshift, first, you need to remember that visible light is a spectrum of color each with a different wavelength. 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. However, one needs to resolve key spectral features in the EBL in order to extract the physics. As this Redshift Rendezvous, it ends going on innate one of the favored books Redshift Rendezvous collections that we have. ![]() ![]() 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. ![]()
