Abstract:
The Massive and Distant Clusters of WISE Survey 2 (MaDCoWS2) is a new
survey designed as the successor of the original MaDCoWS survey.
MaDCoWS2 improves upon its predecessor by using deeper optical and
infrared data and a more powerful detection algorithm (PZWav). As
input to the search, we use grz photometry from the DECam Legacy
Survey (DECaLS) in combination with W1 and W2 photometry from the
CatWISE2020 catalog to derive the photometric redshifts with full
redshift probability distribution functions for Wide-field Infrared
Survey Explorer (WISE)-selected galaxies. Cluster candidates are then
detected using the PZWav algorithm to find three-dimensional galaxy
overdensities from the sky positions and photometric redshifts. This
paper provides the first MaDCoWS2 data release, covering
1461 (1838 without masking) deg2 centered on the Hyper-SuprimeCam
Subaru Strategic Program equatorial fields. Within this region, we
derive a catalog of 22,970 galaxy cluster candidates detected at a
signal-to-noise ratio (S/N)>5. These clusters span the redshift range
0.1<z<2, including 1312 candidates at z>1.5. We compare MaDCoWS2 to
six existing catalogs in the area. We rediscover 60%-92% of the
clusters in these surveys at S/N>5. The medians of the absolute
redshift offset are <0.02 relative to these surveys, while the
standard deviations are less than 0.06. The median offsets between the
detection position from MaDCoWS2 and other surveys are less than 0.25
Mpc. We quantify the relation between S/N and gas mass, total mass,
luminosity, and richness from other surveys using a redshift-dependent
power law relation. We find that the S/N-richness relation exhibits
the lowest scatter.
Description:
We introduce a cluster search program called the Massive and Distant
Clusters of WISE Survey 2 (MaDCoWS2). MaDCoWS2 uses infrared data from
CatWISE2020 (Marocco+ 2021, II/365) in conjunction with optical data
from the DESI Legacy Imaging Survey DR9 (LS; Dey+ 2019AJ....157..168D 2019AJ....157..168D ;
see VII/292). The search continues the legacy of MaDCoWS
(Gonzalez+ 2019, J/ApJS/240/33), which detects clusters at 0.7≤z≤1.5
over the full extragalactic sky.
In this paper, we present the first data release from MaDCoWS2,
spanning ∼1500deg2. The final survey will cover >8000deg2. We
focus on the wide areas overlapped with the fall and spring equatorial
fields of the HSC Subaru Strategic Program Wide survey
(Aihara+ 2018PASJ...70S...4A 2018PASJ...70S...4A & 2018PASJ...70S...8A 2018PASJ...70S...8A). The deeper
optical data in the HSC region are valuable for the validation of our
cluster catalog, and the HSC CAMIRA catalog (Oguri+ 2018, J/PASJ/70/S20)
provides a comparison cluster catalog based upon this deeper optical data.
The cosmology used throughout this paper follows the ΛCDM
cosmology from Planck Col.+ (2020A&A...641A...6P 2020A&A...641A...6P) with
ωm=0.315 and H0=67.4km/s/Mpc.
