Abstract:
We present a catalog of 5437 morphologically classified sources in the
direction of the Perseus galaxy cluster core, among them 496
early-type low-mass galaxy candidates. The catalog is primarily based
on V-band imaging data acquired with the William Herschel Telescope,
which we used to conduct automated source detection and derive
photometry. We additionally reduced archival Subaru multiband imaging
data in order to measure aperture colors and perform a morphological
classification, benefiting from 0.5" seeing conditions in the r-band
data. Based on morphological and color properties, we extracted a
sample of early-type low-mass galaxy candidates with absolute V-band
magnitudes in the range of -10 to -20mag. In the color-magnitude
diagram, the galaxies are located where the red sequence for
early-type cluster galaxies is expected, and they lie on the
literature relation between absolute magnitude and Sersic index. We
classified the early-type dwarf candidates into nucleated and
nonnucleated galaxies. For the faint candidates, we found a trend of
increasing nucleation fraction toward brighter luminosity or higher
surface brightness, similar to what is observed in other nearby galaxy
clusters. We morphologically classified the remaining sources as
likely background elliptical galaxies, late-type galaxies, edge-on
disk galaxies, and likely merging systems and discussed the expected
contamination fraction through non-early-type cluster galaxies in the
magnitude-size surface brightness parameter space. Our catalog reaches
its 50% completeness limit at an absolute V-band luminosity of -12mag
and a V-band surface brightness of 26mag/arcsec2. This makes it the
largest and deepest catalog with coherent coverage compared to
previous imaging studies of the Perseus cluster.
Description:
We performed the source detection and photometry in our V-band mosaic
of the Perseus cluster core, which we presented and described in
Wittmann+ (2017, J/MNRAS/470/1512 --see their Figure 1 and Figure 1 in
this paper). The mosaic is based on imaging data acquired with the
prime focus imaging platform at the William Herschel Telescope (WHT;
program 2012B/045; PI: T. Lisker). The observations were carried out
2012 November 12 and 13.
The WHT data constitute our primary data set that we used to establish
the catalog. We additionally reduced archival Subaru HSC data in the
g, r, and z bands, which served as an auxiliary data set to improve
the quality of the catalog. The HSC data set was compiled from a
number of mostly overlapping observations taken under two different
proposals in 2014 September and November, obtained from the
Subaru-Mitaka-Okayama-Kiso Archive (SMOKA; Baba+ 2002ASPC..281..298B 2002ASPC..281..298B).
