The Impact of Interpixel Capacitance in CMOS Detectors on PSF shapes and Implications for WFIRST
Arun Kannawadi, Charles A. Shapiro, Rachel Mandelbaum +3
Unlike optical CCDs, near-infrared detectors, which are based on CMOS hybrid readout technology, typically suffer from electrical crosstalk between the pixels. The interpixel capac…
The far-ultraviolet spectra of "cool" PG1159 stars
K. Werner, T. Rauch, J. W. Kruk
We present a comprehensive study of Far Ultraviolet Spectroscopic Explorer (FUSE) spectra (912-1190 A) of two members of the PG1159 spectral class, which consists of hydrogen-defic…
Radiation-Induced Backgrounds in Astronomical Instruments: Considerations for Geo-synchronous Orbit and Implications for the Design of the WFIRST Wide-Field Instrument
Jeffrey W. Kruk, Michael A. Xapsos, Nerses Armani +2
Geo-Synchronous orbits are appealing for Solar or astrophysical observatories because they permit continuous data downlink at high rates. The radiation environment in these orbits…
Wide-Field InfrarRed Survey Telescope-Astrophysics Focused Telescope Assets WFIRST-AFTA 2015 Report
D. Spergel, N. Gehrels, C. Baltay +52
This report describes the 2014 study by the Science Definition Team (SDT) of the Wide-Field Infrared Survey Telescope (WFIRST) mission. It is a space observatory that will address…
