Deep CO(1-0) Observations of z=1.62 Cluster Galaxies with Substantial Molecular Gas Reservoirs and Normal Star Formation Efficiencies
Gregory Rudnick, Jacqueline Hodge, Fabian Walter +9
We present an extremely deep CO(1-0) observation of a confirmed galaxy cluster. We detect two spectroscopically confirmed cluster members in CO(1-0) with . Both gal…
Determining the Halo Mass Scale where Galaxies Lose Their Gas
Gregory Rudnick, Pascale Jablonka, John Moustakas +9
A major question in galaxy formation is how the gas supply that fuels activity in galaxies is modulated by their environment. We use spectroscopy of a set of well characterized clu…
Gemini Observations of Galaxies in Rich Early Environments (GOGREEN) I: Survey Description
Michael L. Balogh, David G. Gilbank, Adam Muzzin +29
We describe a new Large Program in progress on the Gemini North and South telescopes: Gemini Observations of Galaxies in Rich Early Environments (GOGREEN). This is an imaging and d…
ALMA Observations of Gas-Rich Galaxies in z~1.6 Galaxy Clusters: Evidence for Higher Gas Fractions in High-Density Environments
A. G. Noble, M. McDonald, A. Muzzin +16
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 observati…
The Ages of Passive Galaxies in a z=1.62 Protocluster
Donald B. Lee-Brown, Gregory H. Rudnick, Ivelina G. Momcheva +9
We present a study of the relation between galaxy stellar age and mass for 14 members of the protocluster IRC 0218, using multiband imaging and HST G102 and G141 grism spe…
The effect of the environment on the structure, morphology and star-formation history of intermediate-redshift galaxies
Kshitija Kelkar, Meghan E. Gray, Alfonso Aragon-Salamanca +4
With the aim of understanding the effect of the environment on the star formation history and morphological transformation of galaxies, we present a detailed analysis of the colour…
