A coherent study of emission lines from broadband photometry: specific star formation rates and [O iii]/Hβ ratio at 3 lt Z lt 6

Abstract:

We measure the Hα and [O iii] emission line properties as well as specific star formation rates (sSFRs) of spectroscopically confirmed 3 lt; z lt; 6 galaxies in COSMOS from their observed colors versus redshift evolution. Our model describes consistently the ensemble of galaxies including intrinsic properties (age, metallicity, star formation history), dust attenuation, and optical emission lines. We forward-model the measured Hα equivalent widths (EW) to obtain the sSFR out to z sim; 6 witho...
