J/MNRAS/411/2558    Coma cluster galaxies absorption-line indices (Price+, 2011)

The stellar populations of bright Coma cluster galaxies. Price J., Phillipps S., Huxor A., Smith R.J., Lucey J.R. <Mon. Not. R. Astron. Soc., 411, 2558-2585 (2011)> =2011MNRAS.411.2558P
ADC_Keywords: Clusters, galaxy ; Galaxies, spectra ; Abundances Keywords: surveys - galaxies: clusters: individual: Coma - galaxies: evolution - galaxies: stellar content Abstract: In this paper we study the stellar populations of 356 bright, Mr≤-19, Coma cluster members located in a 2° field centred on the cluster core using Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) spectroscopy. We find ∼31 per cent of the sample have significant emission in Hβ, [OIII]5007, Hα or [NII]6585, due to star formation or active galactic nuclei (AGN)/LINER activity. The remaining portion of the sample we describe as passive or quiescent. File Summary:
