Discovery of two gravitationally lensed quasars in the Dark Energy Survey
Adriano Agnello, Tommaso Treu, Fernanda Ostrovski +77
We present spectroscopic confirmation of two new lensed quasars via data obtained at the 6.5m Magellan/Baade Telescope. The lens candidates have been selected from the Dark Energy…
Spurious shear induced by the tree rings of the LSST CCDs
Yuki Okura, Andrés A. Plazas, Morgan May +1
We present an analysis of the impact of the tree rings seen in the candidate sensors of the Large Synoptic Survey Telescope (LSST) on galaxy-shape measurements. The tree rings are…
DESAlert: Enabling Real-Time Transient Follow-Up with Dark Energy Survey Data
A. Poci, K. Kuehn, the DES Collaboration +63
The Dark Energy Survey (DES) is currently undertaking an observational program imaging of the southern hemisphere sky with unprecedented photometric accuracy. In the process…
The LMC geometry and outer stellar populations from early DES data
Eduardo Balbinot, B. X. Santiago, L. Girardi +50
The Dark Energy Camera has captured a large set of images as part of Science Verification (SV) for the Dark Energy Survey. The SV footprint covers a lar ge portion of the outer Lar…
Characterization and correction of charge-induced pixel shifts in DECam
Daniel Gruen, Gary M. Bernstein, Mike Jarvis +4
Interaction of charges in CCDs with the already accumulated charge distribution causes both a flux dependence of the point-spread function (an increase of observed size with flux,…
