From Cluster Cores to the Low-Density Field: Strong Environmental Quenching of Galaxy Star Formation at Low Redshift

Mohamed H. Abdullah, A. E. Abdelaziz, Gillian Wilson +3

We investigate how galaxy star formation activity depends on environment using a sample of 81,647 SDSS galaxies selected over and $9.7\leq\log_{10}(M_\star/h^…

From Cluster Core to Splashback: Linking Dynamical Structure to Multidimensional Galaxy Evolution in the Coma Cluster

Mohamed H. Abdullah, S. W. El-Sogheir, Gillian Wilson +2

We investigate galaxy evolution across the full dynamical structure of the Coma cluster using the GalWCat19 spectroscopic cluster catalog combined with SDSS-based value-added galax…

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…

Galaxy Cluster Detection and Dynamical Analysis in the VIPERS High-Redshift Spectroscopic Survey

Mohamed H. Abdullah, Omnia I. Adly, Gillian Wilson +2

We present a dynamical analysis of galaxy clusters identified in the VIPERS spectroscopic survey within the redshift range 0.5 <= z <= 1.2. Cluster candidates were first detected a…

From the Densest Clusters to the Emptiest Voids: No Evidence For Environmental Effects on the Galaxy Size-Mass Relation at Low Redshift

Mohamed H. Abdullah, Nouran E. Abdelhamid, Rasha M. Samir +1

We present a comprehensive study of the galaxy size-stellar mass relation (SMR) at low redshift (z <= 0.125), using a large spectroscopic sample from the SDSS-DR13 survey. Our goal…

Dynamical Properties and Velocity Dispersion-Mass Relation of Galaxy Clusters from the GOGREEN and GCLASS Surveys

Shrouk Abdulshafy, Mohamed H. Abdullah, Gillian Wilson +2

We investigate a sample of 14 galaxy clusters from the GOGREEN and GCLASS (GG) spectroscopic datasets within the redshift range and cluster masses $\mathr…

Quantifying the Velocity Anisotropy Profile of Galaxy Clusters Using the Uchuu Cosmological Simulation

Mohamed H. Abdullah, Raouf H. Mabrouk, Tomoaki Ishiyama +2

Galaxy clusters are powerful laboratories for studying both cosmic structure formation and galaxy evolution. We present a comprehensive analysis of the velocity anisotropy profile,…
