Description

The relationship between galaxy star formation rates (SFRs) and stellar masses (M∗) is reexamined using a mass-selected sample of ∼62,000 star-forming galaxies at z 1.3 in the COSMOS 2 deg²field. Using new far-infrared photometry from Herschel-PACS and SPIRE and Spitzer-MIPS 24μm, along with derived infrared luminosities from the NRK method based on galaxies’ locations in the restframe color–color diagram (NUV − r) versus (r − K), we are able to more accurately determine total SFRs for our...[Show more]
