Abstract:
We identify a sample of 1959 massive clusters of galaxies in the
redshift range of 0.7<z<1.0 from the survey data of Sloan Digital Sky
Survey (SDSS) and Wide-field Infrared Survey Explorer (WISE). These
clusters are recognized as the overdensity regions of galaxies in the
foreground-cleaned WISE data around the SDSS luminous red galaxies,
having a richness greater than 15 or an equivalent mass
M500≥2.5x1014M☉. Among them, 1505 clusters are identified
for the first time, which significantly enlarge the number of
high-redshift clusters of z>0.75. By comparing them with clusters at
lower redshifts, we confirm that richer clusters host more luminous
brightest cluster galaxies (BCGs) also at high redshifts, and that the
fraction of blue galaxies is larger in clusters at higher redshifts. A
small fraction of BCGs show ongoing star formation or active nuclei.
The number density profile of member galaxies in stacked samples of
clusters shows no significant redshift evolution.
Description:
The high-redshift massive clusters are identified from the WISE data
and the SDSS data by following a few steps. The luminous red galaxies
(LRGs) with spectroscopic redshifts in the SDSS are first taken as BCG
candidates. The photometric data of the SDSS are used to discard stars
and low-redshift galaxies in the WISE catalogue. Galaxy clusters are
then recognized as the overdensity regions in the remaining WISE
source catalogue around the LRGs.
The SDSS performs the optical photometric survey and the follow-up
spectroscopic survey in the northern sky (York et al.
2000AJ....120.1579Y 2000AJ....120.1579Y). The photometric data have been taken at five
broad-bands (u, g, r, i, and z covering 14000deg2 of the sky
(Aihara et al. 2011ApJS..193...29A 2011ApJS..193...29A) reaching a limit of r=22.2mag
(Stoughton et al. 2002AJ....123..485S 2002AJ....123..485S). Among 278 million sources from
the photometric data, 112 million sources have been classified as
stars, and other 166 million sources are classified as galaxies.
The WISE survey observes the whole sky in four mid-infrared bands
(Wright et al. 2010AJ....140.1868W 2010AJ....140.1868W): W1 (3.4µm), W2 (4.6µm), W3
(12µm), and W4 (22µm) with 5σ magnitude limits of 17.1,
15.7, 11.5, and 7.7mag in the Vega system for point sources,
respectively.
For high-redshift galaxies, the W1-band photometric data of WISE are
deeper than the SDSS data due to the slow change of galaxy magnitude
with redshift (Yan et al. 2013AJ....145...16L 2013AJ....145...16L, Cat. J/AJ/145/16). We
therefore identify high-redshift clusters from the WISE source
catalogue, after foreground objects are discarded by using the SDSS
photometric data.
