Updated catalog of 132,684 galaxy clusters and evolution of brightest cluster galaxies
Z. L. Wen, J. L. Han
TL;DR
This paper presents an updated catalog of over 132,000 galaxy clusters from SDSS data, analyzing the evolution of brightest cluster galaxies and their luminosity dependence on cluster richness and redshift.
Contribution
It provides a comprehensive catalog of galaxy clusters with spectroscopic redshifts and insights into BCG luminosity evolution across different cluster environments.
Findings
BCGs are more luminous in richer clusters.
BCG luminosity increases with redshift.
The catalog includes 132,684 clusters with spectroscopic data.
Abstract
We identified 132,684 clusters in the redshift range of 0.05<z<0.8 from SDSS DR8. The spectroscopic redshifts of 52,683 clusters have been included in the catalog using SDSS DR9 data. We found that BCGs are more luminous in richer clusters and at higher redshifts.
