Abstract:
Utilizing the SDSS-DR13 spectroscopic data set, we create a new
publicly available catalog of 1800 galaxy clusters (GalWeight cluster
catalog, GalWCat19) and a corresponding catalog of 34,471 identified
member galaxies. The clusters are identified from overdensities in
redshift phase space. The GalWeight technique introduced by Abdullah+
(2018ApJ...861...22A 2018ApJ...861...22A) is then applied to identify cluster members. The
completeness of the cluster catalog (GalWCat19) and the procedure
followed to determine cluster mass are tested on the Bolshoi N-body
simulations. The 1800 GalWCat19 clusters range in redshift between
0.01 and 0.2 and have masses in the range of
(0.4-14)x1014h-1M☉. The cluster catalog provides a large
number of cluster parameters, including sky position, redshift,
membership, velocity dispersion, and mass at overdensities
Δ=500, 200, 100, and 5.5. The 34471 member galaxies are
identified within the radius at which the density is 200 times the
critical density of the universe. The galaxy catalog provides the
coordinates of each galaxy and the ID of the cluster that the galaxy
belongs to. The cluster velocity dispersion scales with mass as
log(σ200)=log(946±52km/s)+
(0.349±0.142)log[h(z)M200/10^1 5^M_☉], with a scatter of
δlogσ=0.06±0.04.
Description:
Using photometric and spectroscopic databases from SDSS-DR13, we
extract data for 704,200 galaxies. These galaxies fulfill the
following set of criteria: spectroscopic detection, photometric and
spectroscopic classification as a galaxy (by the automatic pipeline),
spectroscopic redshift between 0.001 and 0.2, r-band magnitude<18 and
well-measured redshift (SpecObj.zWarning=0). The clusters are
identified from overdensities in redshift phase space (see Section 2.2).
The GalWeight technique introduced by Abdullah+ (2018ApJ...861...22A 2018ApJ...861...22A)
is then applied to identify cluster members (see Section 2.3).
