The Wide Field Infrared Survey Telescope: 100 Hubbles for the 2020s
Rachel Akeson, Lee Armus, Etienne Bachelet +103
The Wide Field Infrared Survey Telescope (WFIRST) is a 2.4m space telescope with a 0.281 deg^2 field of view for near-IR imaging and slitless spectroscopy and a coronagraph designe…
An Overview of the LSST Image Processing Pipelines
James Bosch, Yusra AlSayyad, Robert Armstrong +31
The Large Synoptic Survey Telescope (LSST) is an ambitious astronomical survey with a similarly ambitious Data Management component. Data Management for LSST includes processing on…
Precision Projector Laboratory: Detector Characterization with an Astronomical Emulation Testbed
Charles Shapiro, Roger Smith, Eric Huff +7
As astronomical observations from space benefit from improved sensitivity, the effectiveness of scientific programs is becoming limited by systematics that often originate in poorl…
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…
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…
