Abstract:
We study the mid-infrared (MIR) properties of the galaxies in the
A2199 supercluster at z=0.03 to understand the star formation activity
of galaxy groups and clusters in the supercluster environment. Using
the Wide-field Infrared Survey Explorer (WISE) data, we find no
dependence of mass-normalized integrated star formation rates of
galaxy groups/clusters on their virial masses. We classify the
supercluster galaxies into three classes in the MIR color-luminosity
diagram: MIR blue cloud (massive, quiescent, and mostly early-type),
MIR star-forming sequence (mostly late-type), and MIR green valley
galaxies. These MIR green valley galaxies are distinguishable from the
optical green valley galaxies in the sense that they belong to the
optical red sequence. We find that the fraction of each MIR class does
not depend on the virial mass of each group/cluster. We compare the
cumulative distributions of surface galaxy number density and
cluster/group-centric distance for the three MIR classes. MIR green
valley galaxies show the distribution between MIR blue cloud and MIR
star-forming (SF) sequence galaxies. However, if we fix galaxy
morphology, early- and late-type MIR green valley galaxies show
different distributions. Our results suggest a possible evolutionary
scenario of these galaxies: (1) late-type MIR SF sequence galaxies -->
(2) late-type MIR green valley galaxies --> (3) early-type MIR green
valley galaxies --> (4) early-type MIR blue cloud galaxies. In this
sequence, the star formation of galaxies is quenched before the
galaxies enter the MIR green valley, and then morphological
transformation occurs in the MIR green valley.
Description:
We used the galaxy catalog of the A2199 supercluster given by Hwang+,
2012ApJ...752...64H 2012ApJ...752...64H (H12). H12 compiled the multi-wavelength data of
the galaxies at mr<17.77 from the Sloan Digital Sky Survey Data
Release 7 (SDSS DR7, II/294) and the WISE data (II/311).
