Key Technologies for the Wide Field Infrared Survey Telescope Coronagraph Instrument
Vanessa P. Bailey, Lee Armus, Bala Balasubramanian +84
The Wide Field Infrared Survey Telescope (WFIRST) Coronagraph Instrument (CGI) is a high-contrast imager and integral field spectrograph that will enable the study of exoplanets an…
Smartphone scene generator for efficient characterization of visible imaging detectors
Michael Bottom, Leo S. Neat, Leon K. Harding +3
Full characterization of imaging detectors involves subjecting them to spatially and temporally varying illumination patterns over a large dynamic range. Here we present a scene ge…
CHIMERA: a wide-field, multi-color, high-speed photometer at the prime focus of the Hale telescope
Leon K. Harding, Gregg Hallinan, Jennifer Milburn +7
The Caltech HIgh-speed Multi-color camERA (CHIMERA) is a new instrument that has been developed for use at the prime focus of the Hale 200-inch telescope. Simultaneous optical imag…
Technology advancement of the CCD201-20 EMCCD for the WFIRST coronagraph instrument: sensor characterization and radiation damage
Leon K. Harding, Richard T. Demers, Michael Hoenk +15
The Wide Field InfraRed Survey Telescope-Astrophysics Focused Telescope Asset (WFIRST-AFTA) mission is a 2.4-m class space telescope that will be used across a swath of astrophysic…
Detection of a faint fast-moving near-Earth asteroid using synthetic tracking technique
Chengxing Zhai, Michael Shao, Bijan Nemati +6
We report a detection of a faint near-Earth asteroid (NEA), which was done using our synthetic tracking technique and the CHIMERA instrument on the Palomar 200-inch telescope. This…
PTF1 J191905.19+481506.2 - A Partially Eclipsing AM CVn System Discovered in the Palomar Transient Factory
David Levitan, Thomas Kupfer, Paul J. Groot +11
We report on PTF1 J191905.19+481506.2, a newly discovered, partially eclipsing, outbursting AM CVn system found in the Palomar Transient Factory synoptic survey. This is only the s…
Finding Very Small Near-Earth Asteroids using Synthetic Tracking
Michael Shao, Bijan Nemati, Chengxing Zhai +4
We present an approach that significantly increases the sensitivity for finding and tracking small and fast near Earth asteroids (NEA's). This approach relies on a combined use of…
Spin-orbit alignment in the very low mass binary regime: The L dwarf tight binary 2MASSW J0746425+200032AB
Leon K. Harding, Gregg Hallinan, Quinn M. Konopacky +4
Studies of solar-type binaries have found coplanarity between the equatorial and orbital planes of systems with 40 AU separation. By comparison, the alignment of the equatorial…
