TL;DR
This study uses Herschel far-IR data to analyze the star formation and dust properties of z~2 galaxies selected by stellar mass from the GOODS NICMOS Survey, revealing insights into dust obscuration and star formation rates.
Contribution
First to combine Herschel far-IR observations with a stellar mass-selected galaxy sample at z~2, providing new measurements of IR luminosity and dust temperature for this population.
Findings
Mean IR luminosity log L_IR ~ 12.36 L_sun
Star formation rate ~ 280 M_sun/yr from IR+UV
Dust obscured star formation increases with stellar mass
Abstract
We present a study of the far-IR properties of a stellar mass selected sample of 1.5 < z < 3 galaxies with log(M_*/M_sun) > 9.5 drawn from the GOODS NICMOS Survey (GNS), the deepest H-band Hubble Space Telescope survey of its type prior to the installation of WFC3. We use far-IR and sub-mm data from the PACS and SPIRE instruments on-board Herschel, taken from the PACS Evolutionary Probe (PEP) and Herschel Multi-Tiered Extragalactic Survey (HerMES) key projects respectively. We find a total of 22 GNS galaxies, with median log(M_*/M_sun) = 10.8 and z = 2.0, associated with 250 um sources detected with SNR > 3. We derive mean total IR luminosity log L_IR (L_sun) = 12.36 +/- 0.05 and corresponding star formation rate SFR_(IR+UV) = (280 +/- 40) M_sun/yr for these objects, and find them to have mean dust temperature T_dust ~ 35 K. We find that the SFR derived from the far-IR photometry…
