Galaxy clusters and their outskirts: the "red sequence", star formation rate, stellar mass

Flera G. Kopylova, Alexander I. Kopylov

We study the outskirts ($R<3R_{200c}$) of 40 groups and clusters of galaxies of the local Universe ($0.02<z<0.045$) with 300~km~s${}^{-1}<\sigma <950$~km~s${}^{-1}$. Using the SDSS DR10 cata…
