Abstract:
We present a catalog of ultra-diffuse galaxies (UDGs) in the Coma
cluster. UDGs are a subset of low surface brightness (SB) galaxies
with very large effective radii defined by van Dokkum et al.
(2015ApJ...798L..45V 2015ApJ...798L..45V). We surveyed the Subaru data archive for deep
Suprime-Cam/Subaru R-band images, and used data covering the
1.7x2.7° region of the Coma cluster. The data are ∼1 magnitude
deeper than the data of van Dokkum et al. in limiting SB. This paper
explains the details of our sample selection procedure. This UDG
catalog includes positions, magnitudes, effective radii, mean and
central SBs, and colors (when available). Comparisons with previous
galaxy catalogs in the literature are performed, and we show that the
current catalog is the largest for UDGs. We also discuss that most of
the UDGs are members of the Coma cluster, and the major axis of the
UDGs tends to align toward the cluster center (radial alignment).
Description:
We retrieved a wide W-C-RC band (R-band) survey of the Coma cluster of
Suprime-Cam from the Subaru public archive (SMOKA;
Baba et al. 2002ASPC..281..298B 2002ASPC..281..298B) between 2011 Mar 02 and 2011 Apr 01.
