HST/WFC3 grism observations of clusters: The cluster vs. field stellar mass-size relation and evidence for size growth of quiescent galaxies from minor mergers

Jasleen Matharu, Adam Muzzin, Gabriel B. Brammer +13

Minor mergers are thought to be responsible for the size growth of quiescent field galaxies with decreasing redshift. We test this hypothesis using the cluster environment as a lab…

Resolving CO (2-1) in z~1.6 Gas-Rich Cluster Galaxies with ALMA: Rotating Molecular Gas Disks with Possible Signatures of Gas Stripping

A. G. Noble, A. Muzzin, M. McDonald +10

We present the first spatially-resolved observations of molecular gas in a sample of cluster galaxies beyond z>0.1. Using ALMA, we detect CO (2-1) in 8 z~1.6 cluster galaxies, all…

GalWeight: A New and Effective Weighting Technique for Determining Galaxy Cluster and Group Membership

Mohamed H. Abdullah, Gillian Wilson, Anatoly Klypin

We introduce GalWeight, a new technique for assigning galaxy cluster membership. This technique is specifically designed to simultaneously maximize the number of bona fide cluster…

X-ray versus infrared selection of distant galaxy clusters: A case study using the XMM-LSS and SpARCS cluster samples

J. P. Willis, M. E. Ramos-Ceja, A. Muzzin +3

We present a comparison of two samples of z>0.8 galaxy clusters selected using different wavelength-dependent techniques and examine the physical differences between them. We consi…

The Evolution of Environmental Quenching Timescales to

R. Foltz, G. Wilson, A. Muzzin +18

Using a sample of 4 galaxy clusters at and 10 galaxy clusters at , we measure the environmental quenching timescale, , corresponding to the…
