The remarkable Hubble Space Telescope (HST) data sets from the CANDELS, HUDF09, HUDF12, ERS, and BoRG/HIPPIES programs have allowed us to map evolution of rest-frame UV luminosity function (LF) . We develop new color criteria that more optimally utilize full wavelength coverage optical, near-IR, mid-IR observations over our search fields, while simultaneously minimizing incompleteness eliminating redshift gaps. identified 5859, 3001, 857, 481, 217, 6 galaxy candidates at , respectively,...
A very simple physical model of galaxies is one in which the formation stars instantaneously regulated by mass gas a reservoir with loss scaling star-formation rate (SFR). This links together three different aspects evolving galaxy population: (1) cosmic time evolution specific (sSFR) relative to growth halos, (2) gas-phase metallicities across population and over time, (3) ratio stellar dark matter halos. The regulator defined consumption timescale (ε−1) loading λ wind outflow λ·SFR....
