Abstract:
Accurately determining the mass of galaxy clusters is fundamental for
many studies of cosmology and galaxy evolution. We collect and rescale
the cluster masses of 1191 clusters of 0.05<z<0.75 estimated by X-ray
or Sunyaev-Zeldovich measurements and use them to calibrate the
optical mass proxy. The total r-band luminosity (in units of L*) of
these clusters is obtained by using spectroscopic and photometric data
of the Sloan Digital Sky Survey (SDSS). We find that the correlation
between the cluster mass M500 and total r-band luminosity L500
significantly evolves with redshift. After correcting for the
evolution, we define a new cluster richness RL*,500=L500E(z)1.40
as the optical mass proxy. By using this newly defined richness and
the recently released SDSS DR12 spectroscopic data, we update the
WHL12 (Wen et al. 2012, J/ApJS/199/34) cluster catalog and identify
25419 new rich clusters at high redshift. In the SDSS spectroscopic
survey region, about 89% of galaxy clusters have spectroscopic
redshifts. The mass can be estimated with a scatter of 0.17dex for the
clusters in the updated catalog.
