CLASH-VLT: A Highly Precise Strong Lensing Model of the Galaxy Cluster RXC J2248.7-4431 (Abell S1063) and Prospects for Cosmography
G. B. Caminha, C. Grillo, P. Rosati +32
We perform a comprehensive study of the total mass distribution of the galaxy cluster RXCJ2248 () with a set of high-precision strong lensing models, which take advantage…
Observation and Confirmation of Six Strong Lensing Systems in The Dark Energy Survey Science Verification Data
B. Nord, E. Buckley-Geer, H. Lin +89
We report the observation and confirmation of the first group- and cluster-scale strong gravitational lensing systems found in Dark Energy Survey (DES) data. Through visual inspect…
Discovery of a faint, star-forming, multiply lensed, Lyman-alpha blob
G. B. Caminha, W. Karman, P. Rosati +7
We report the discovery of a multiply lensed Lyman- blob (LAB) behind the galaxy cluster AS1063 using the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (V…
The story of supernova 'Refsdal' told by MUSE
C. Grillo, W. Karman, S. H. Suyu +10
We present MUSE observations in the core of the HFF galaxy cluster MACS J1149.5+2223, where the first magnified and spatially-resolved multiple images of SN 'Refsdal' at redshift 1…
CLASH-VLT: Dissecting the Frontier Fields Galaxy Cluster MACS J0416.1-2403 with Spectra of Member Galaxies
I. Balestra, A. Mercurio, B. Sartoris +33
We present VIMOS-VLT spectroscopy of the Frontier Fields cluster MACS~J0416.1-2403 (z=0.397). Taken as part of the CLASH-VLT survey, the large spectroscopic campaign provided more…
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…
"Refsdal" meets Popper: comparing predictions of the re-appearance of the multiply imaged supernova behind MACSJ1149.5+2223
T. Treu, G. Brammer, J. M. Diego +25
Supernova "Refsdal," multiply imaged by cluster MACSJ1149.5+2223, represents a rare opportunity to make a true blind test of model predictions in extragalactic astronomy, on a time…
CLASH-VLT: Substructure in the galaxy cluster MACS J1206.2-0847 from kinematics of galaxy populations
M. Girardi, A. Mercurio, I. Balestra +35
In the effort to understand the link between the structure of galaxy clusters and their galaxy populations, we focus on MACSJ1206.2-0847 at z~0.44 and probe its substructure in the…
