Abstract:
We present a new catalog and images of interacting and merging
galaxies obtained with morphological identification from
Canada-France-Hawaii Telescope observations. We first used a
morphological pattern recognition searching routine to select possible
candidates, and then visually inspected the images of these candidates
to identify true merging/interacting sources. We discover 15147 new
pairs of merging galaxies within 422deg2 of Red Sequence Cluster
Survey 2. Furthermore, we also find nine new candidates of galaxy
clusters by searching for regions with significant density
enhancements of merging galaxies. This catalog has the largest number
of morphologically identified interacting and merging galaxies based
on consistent searching criteria. These sources provide a uniform
sample of merging galaxies for further photometric and spectroscopic
studies of galaxy evolution.
Description:
In this supplement, we present a catalog and images of morphologically
identified merging galaxies in Red Sequence Cluster Survey 2 (RCS2)
(Yee et al., 2007ASPC..379..103Y 2007ASPC..379..103Y). RCS2 is a large sky survey using the
Canada-France-Hawaii Telescope (CFHT) to look for galaxy clusters out
to z∼1.
