Autor: Delahaye, A.G. Webb, T.M.A. Nantais, J. Degroot, A. Wilson, G. Muzzin, A. Yee, H.K.C. Foltz, R. Noble, A.G. Demarco, R. Tudorica, A. Cooper, M.C. Lidman, C. Perlmutter, S. Hayden, B. Boone, K. Surace, J.

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 a comparison field sample selected from the UKIDSS Deep Survey. Using near-...

Discovery of Ram-pressure Stripped Gas around an Elliptical Galaxy in Abell 2670

Autor: Sheen, Y.-K. Smith, R. Jaffé, Y. Kim, M. Yi, S.K. Duc, P.-A. Nantais, J. Candlish, G. Demarco, R. Treister, E.

Studies of cluster galaxies are increasingly finding galaxies with spectacular one-sided tails of gas and young stars, suggestive of intense ram-pressure stripping. These so-called "jellyfish" galaxies typically have late-type morphology. In this paper, we present Multi Unit Spectroscopic Explore...

Weak lensing magnification of SpARCS galaxy clusters

Autor: Tudorica, A. Hildebrandt, H. Tewes, M. Hoekstra, H. Morrison, C.B. Muzzin, A. Wilson, G. Yee, H.K.C. Lidman, C. Hicks, A. Nantais, J. Erben, T. Van Der Burg, R.F.J. Demarco, R.

Context. Measuring and calibrating relations between cluster observables is critical for resource-limited studies. The mass-richness relation of clusters offers an observationally inexpensive way of estimating masses. Its calibration is essential for cluster and cosmological studies, especially f...

ALMA Observations of Gas-rich Galaxies in z ~ 1.6 Galaxy Clusters: Evidence for Higher Gas Fractions in High-density Environments

Autor: Noble, A.G. McDonald, M. Muzzin, A. Nantais, J. Rudnick, G. Van Kampen, E. Webb, T.M.A. Wilson, G. Yee, H.K.C. Boone, K. Cooper, M.C. DeGroot, A. Delahaye, A. Demarco, R. Foltz, R. Hayden, B. Lidman, C. Manilla-Robles, A. Perlmutter, S.

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 from the Spitzer Adaptation of the Red-sequence Cluster Survey. We augmen...
