Gemini North Adaptive Optics (GNAO) facility overview and status updates
Gaetano Sivo, Julia Scharwächter, Manuel Lazo +54
The Gemini North Adaptive Optics (GNAO) facility is the upcoming AO facility for Gemini North providing a state-of-the-art AO system for surveys and time domain science in the era…
MC: Boosted AGN and star-formation activity in CIZA J2242.8+5301, a massive post-merger cluster at z=0.19
David Sobral, Andra Stroe, William A. Dawson +5
Cluster mergers may play a fundamental role in the formation and evolution of cluster galaxies. Stroe et al. (2014) revealed unexpected over-densities of candidate H emitters ne…
Multi-wavelength study of XMMU J2235.3-2557: the most massive galaxy cluster at z > 1
P. Rosati, P. Tozzi, R. Gobat +14
[Abridged] XMMU J2235.3-2557 is one of the most distant X-ray selected clusters, spectroscopically confirmed at z=1.39. We characterize the galaxy populations of passive members, t…
New Multiply-Lensed Galaxies Identified in ACS/NIC3 Observations of Cl0024+1654 Using an Improved Mass Model
Adi Zitrin, Tom Broadhurst, Keiichi Umetsu +9
We present an improved strong-lensing analysis of Cl0024+1654 (=0.39) using deep HST/ACS/NIC3 images, based on 33 multiply-lensed images of 11 background galaxies. These are fou…
z~7-10 Galaxies behind Lensing Clusters: Contrast with Field Search Results
Rychard J. Bouwens, Garth D. Illingworth, Larry D. Bradley +6
We conduct a search for z>~7 dropout galaxies behind 11 massive lensing clusters using 21 arcmin**2 of deep HST NICMOS, ACS, and WFPC2 image data. In total, over this entire area,…
