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 $0.03\le z\le 0.075$ and $9.7\leq\log_{10}(M_\star/h^…
