Laboratory measurement of the brighter-fatter effect in an H2RG infrared detector
Andrés A. Plazas, Charles A. Shapiro, R. Smith +2
The "brighter-fatter" (BF) effect is a phenomenon (originally discovered in charge coupled devices) in which the size of the detector point spread function (PSF) increases with bri…
Dark Energy Survey Year 1 Results: Galaxy Sample for BAO Measurement
M. Crocce, A. J. Ross, I. Sevilla-Noarbe +84
We define and characterise a sample of 1.3 million galaxies extracted from the first year of Dark Energy Survey data, optimised to measure Baryon Acoustic Oscillations in the prese…
Dark Energy Survey Year 1 Results: Weak Lensing Shape Catalogues
J. Zuntz, E. Sheldon, S. Samuroff +104
We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set, covering 1500 square degrees with a median redshift of . The catalogues cover two main fie…
Nonlinearity and pixel shifting effects in HXRG infrared detectors
A. A. Plazas, C. Shapiro, R. Smith +2
We study the nonlinearity (NL) in the conversion from charge to voltage in infrared detectors (HXRG) for use in precision astronomy. We present laboratory measurements of the NL fu…
Astrometric calibration and performance of the Dark Energy Camera
G. M. Bernstein, R. Armstrong, A. A. Plazas +53
We characterize the ability of the Dark Energy Camera (DECam) to perform relative astrometry across its 500~Mpix, 3 deg^2 science field of view, and across 4 years of operation. Th…
Eight new luminous z > 6 quasars selected via SED model fitting of VISTA, WISE and Dark Energy Survey Year 1 Observations
S. L. Reed, R. G. McMahon, P. Martini +60
We present the discovery and spectroscopic confirmation with the ESO NTT and Gemini South telescopes of eight new 6.0 < z < 6.5 quasars with z < 21.0. These quasars were pho…
