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…
The 31 Deg Release of the Stripe 82 X-ray Survey: The Point Source Catalog
Stephanie M. LaMassa, C. Megan Urry, Nico Cappelluti +23
We release the next installment of the Stripe 82 X-ray survey point-source catalog, which currently covers 31.3 deg of the Sloan Digital Sky Survey (SDSS) Stripe 82 Legacy fiel…
Weak-Lensing Mass Calibration of the Atacama Cosmology Telescope Equatorial Sunyaev-Zeldovich Cluster Sample with the Canada-France-Hawaii Telescope Stripe 82 Survey
N. Battaglia, A. Leauthaud, H. Miyatake +39
Mass calibration uncertainty is the largest systematic effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from th…
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…
Wide-Field Lensing Mass Maps from DES Science Verification Data
C. Chang, V. Vikram, B. Jain +81
We present a mass map reconstructed from weak gravitational lensing shear measurements over 139 sq. deg from the Dark Energy Survey (DES) Science Verification data. The mass map pr…
DES J0454-4448: Discovery of the First Luminous z > 6 Quasar from the Dark Energy Survey
S. L. Reed, R. G. McMahon, M. Banerji +59
We present the first results of a survey for high redshift, z 6, quasars using izY multi-colour photometric observations from the Dark Energy Survey (DES). Here we report the…
