Young Galaxy Candidates in the Hubble Frontier Fields. II. MACS,J0416-2403
Leopoldo Infante, Wei Zheng, Nicolas Laporte +14
We searched for z > 7 Lyman-break galaxies (LBGs) in the optical-to-mid-infrared Hubble Frontier Field and associated parallel field observations of the strong-lensing cluster MACS…
CLASH-VLT: Environment-driven evolution of galaxies in the z=0.209 cluster Abell 209
M. Annunziatella, A. Mercurio, A. Biviano +19
The analysis of galaxy properties and the relations among them and the environment, can be used to investigate the physical processes driving galaxy evolution. We study the cluster…
Star Formation Activity in CLASH Brightest Cluster Galaxies
Kevin Fogarty, Marc Postman, Thomas Connor +2
The CLASH X-ray selected sample of 20 galaxy clusters contains ten brightest cluster galaxies (BCGs) that exhibit significant (5 ) extinction-corrected star formation rates (…
The mass distribution in an assembling super galaxy group at
Merijn Smit, Tim Schrabback, Malin Velander +4
We present a weak gravitational lensing analysis of supergroup SG11201202, consisting of four distinct X-ray-luminous groups, that will merge to form a cluster comparable in mas…
Galaxies Probing Galaxies at High Resolution: Co-Rotating Gas Associated with a Milky Way Analog at z=0.4
Aleksandar M. Diamond-Stanic, Alison L. Coil, John Moustakas +5
We present results on gas flows in the halo of a Milky Way-like galaxy at z=0.413 based on high-resolution spectroscopy of a background galaxy. This is the first study of circumgal…
Measuring subhalo mass in redMaPPer clusters with CFHT Stripe 82 Survey
Ran Li, Huanyuan Shan, Jean-Paul Kneib +10
We use the shear catalog from the CFHT Stripe-82 Survey to measure the subhalo masses of satellite galaxies in redMaPPer clusters. Assuming a Chabrier Initial Mass Function (IMF) a…
