Abstract:
Based on the DESI Legacy Imaging Surveys released data and available
spectroscopic redshifts, we identify 1.58 million clusters of galaxies
by searching for the overdensity of the stellar mass distribution of
galaxies within redshift slices around preselected massive galaxies,
with 877,806 clusters being found for the first time. The identified
clusters have an equivalent mass of M500≥0.47x1014M☉ with
an uncertainty of 0.2dex. The redshift distribution of clusters
extends to z∼1.5, and 338,841 clusters have spectroscopic redshifts.
Our cluster sample includes most of the rich optical clusters in
previous catalogs, more than 95% of the massive Sunyaev-Zeldovich
clusters, and 90% of the ROSAT and eROSITA X-ray clusters. From the
light distributions of the member galaxies, we derive the dynamical
state parameters for 27,685 rich clusters and find no significant
evolution of the dynamical state with redshift. We find that the
stellar mass of the brightest cluster galaxies grows by a factor of 2
since z=1.
Description:
Recently, the Dark Energy Spectroscopic Instrument (DESI) Legacy
Surveys have been carried out, and the released data in the three
optical bands (g band, r band, and z band) are one magnitude deeper
than the SDSS. Incorporating the public DECam data, the DESI Legacy
Surveys cover a sky area of more than 20000deg2.
The DESI Legacy Imaging Surveys (Dey+ 2019AJ....157..168D 2019AJ....157..168D) consist of
three projects, including the Dark Energy Camera Legacy Survey
(DECaLs), the Beijing-Arizona Sky Survey (BASS), and the Mayall z-band
Legacy Survey (MzLS). We analyze the DR9 and DR10 data independently
for cluster identification in this work. The latest DR10 data cover a
larger sky area, with some overlapped areas with DR9 and including new
i-band data from the NOIRLab Data Archive. See Section 2.
Throughout this paper, we assume a flat Lambda cold dark matter
cosmology, taking H0=70km/s/Mpc, Ωm=0.3, and
ΩΛ=0.7. All magnitudes are given in the AB system.
