Cross-correlation of gravitational lensing from DES Science Verification data with SPT and Planck lensing
D. Kirk, Y. Omori, A. Benoit-Lévy +89
We measure the cross-correlation between weak lensing of galaxy images and of the cosmic microwave background (CMB). The effects of gravitational lensing on different sources will…
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…
Crowdsourcing quality control for Dark Energy Survey images
P. Melchior, E. Sheldon, A. Drlica-Wagner +47
We have developed a crowdsourcing web application for image quality control employed by the Dark Energy Survey. Dubbed the "DES exposure checker", it renders science-grade images d…
RHAPSODY-G simulations II - Baryonic growth and metal enrichment in massive galaxy clusters
Davide Martizzi, Oliver Hahn, Hao-Yi Wu +3
We study the evolution of the stellar component and the metallicity of both the intracluster medium and of stars in massive ( M) sim…
Rhapsody-G simulations I: the cool cores, hot gas and stellar content of massive galaxy clusters
Oliver Hahn, Davide Martizzi, Hao-Yi Wu +3
We present the Rhapsody-G suite of cosmological hydrodynamic AMR zoom simulations of ten massive galaxy clusters at the scale. These simulat…
Eight Ultra-faint Galaxy Candidates Discovered in Year Two of the Dark Energy Survey
The DES Collaboration, A. Drlica-Wagner, K. Bechtol +74
We report the discovery of eight new ultra-faint dwarf galaxy candidates in the second year of optical imaging data from the Dark Energy Survey (DES). Six of these candidates are d…
