ALMA Observations of Gas-rich Galaxies in z ~ 1.6 Galaxy Clusters: Evidence for Higher Gas Fractions in High-density Environments
(Institute of Physics Publishing, 2017-06)
We present ALMA CO (2-1) detections in 11 gas-rich cluster galaxies at z ∼ 1.6, constituting the largest sample of molecular gas measurements in z > 1.5 clusters to date. The observations span three galaxy clusters, derived ...
Galaxy Merger Candidates in High-redshift Cluster Environments
(Institute of Physics Publishing, 2017-07)
We compile a sample of spectroscopically and photometrically selected cluster galaxies from four high-redshift galaxy clusters (1.59 < z < 1.71) from the Spitzer Adaptation of the Red-Sequence Cluster Survey (SpARCS), and ...
