Stellar mass -- halo mass relation for the brightest central galaxies of X-ray clusters since z~0.65

Understand

We present the brightest cluster galaxies (BCGs) catalog for SPectroscoic IDentification of eROSITA Sources (SPIDERS) DR14 cluster program value-added catalog.

• We list the 416 BCGs identified as part of this process, along with their stellar mass, star formation rates, and morphological properties.
• We identified the BCGs based on the available spectroscopic data from SPIDERS and photometric data from SDSS.
• We computed stellar masses and SFRs of the BCGs on the basis of SDSS, WISE, and GALEX photometry using spectral energy distribution fitting.
