Abstract:	摘要： Using a large optically selected sample of field and group galaxies drawn from the Pan-STARRS1 Medium-Deep Survey (PS1/MDS), we present a detailed analysis of the specific star formation rate (SSFR)-stellar mass (M sub()) relation, as well as the quiescent fraction versus M sub() relation in different environments. Using this large galaxy sample, we confirm that the fraction of quiescent galaxies is strongly dependent on environment at a fixed stellar mass, but that the amplitude and the slope of the star-forming sequence is similar between the field and groups: in other words, the SSFR-density relation at a fixed stellar mass is primarily driven by the change in the star-forming and quiescent fractions between different environments rather than a global suppression in the star formation rate for the star-forming population. 出版者： United States 出版日期： 2014-02-10 出處： The Astrophysical journal, 2014-02, Vol.782 (1), p.33-16 資源來源： Institute of Physics Journals 識別號： ISSN: 0004-637X 識別號： EISSN: 1538-4357 識別號： DOI: 10.1088/0004-637X/782/1/33
