VizieR Online Data Catalog: Spectroscopic properties of BOSS compact galaxies (Damjanov+, 2014)
Abstract
We use the BOSS DR10 data set (Ahn et al. 2014ApJS..211...17A) and employ the selection criteria of Damjanov et al. (2013ApJ...775L..48D) to select compact galaxy candidates in the redshift range 0.2<z<0.6. We search for stellar-like objects with spectroscopic redshifts in the redshift range of interest (22288 sources) and exclude all spectroscopically confirmed quasars (14108 sources) and actively star-forming galaxies (by requiring the equivalent width of the [OII]λλ3726, 3729 emission line to be EW [OII]<5Å; 7299 sources excluded). In addition, we inspect every pre-selected spectrum to identify a 4000Å break and several absorption features including the Balmer series, Ca H+K, and G band. We also apply a cut to the inferred dynamical mass at Mdyn=1010Msun to construct a sample of compact quiescent systems as massive as high- and low-redshift comparison samples (see Sections 4 and 5.3). The final list of BOSS compact galaxy candidates at redshift 0.2<z<0.6 contains 198 objects.
