Calibration of the optical mass proxy for clusters of galaxies and an update of the WHL12 cluster catalog

Understand

Accurately determining the mass of galaxy clusters is fundamental for many studies on 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^{\ast}) of these clusters are obtained by using spectroscopic and photometric data of the Sloan Digital Sky Survey (SDSS).
• We find that the correlation between the cluster mass M_{500} and total r-band luminosity L_{500} significantly evolves with redshift.
