Hidden Connections: Tracing the BCG Stellar Mass-Halo Mass Relation in the SDSS-GalWCat19 Cluster Catalog
Mohamed H. Abdullah, Rasha M. Samir, Nouran E. Abdelhamid +5
The stellar-to-halo mass (SMHM) relation of brightest cluster galaxies (BCGs) provides key insight into the connection between BCG growth and the assembly of their host halos. We a…
Possible Relations between Brightest Central Galaxies and Their Host Galaxies Clusters and Groups
R. M. Samir, A. A. Shaker
The r-band of the Sloan Digital Sky Survey (SDSS) for 17,924 brightest cluster galaxies (BCGs) in clusters and groups within 0.02 z 0.20 are used to study possible environmental re…
Color similarity study among small galaxy groups members
Ahmed M. Fouad, Z. Awad, A. A. Shaker +1
We applied a membership test based on the color similarity of group members to detect the discordant galaxies in small groups (quintets) that had been determined by the Friends-of-…
