The Pandora SmallSat: post-launch operations and mission update
Trevor O. Foote, Elisa V. Quintana, Jessie L. Dotson +41
The Pandora SmallSat is a NASA flight project designed to study the atmospheres of exoplanets. Transmission spectroscopy of transiting exoplanets provides our best opportunity to i…
The Nancy Grace Roman Space Telescope Wide Field Instrument: Characterization of the Brighter-Fatter Effect in a Roman H4RG-10 Detector using the Talbot Effect
Jennie Paine, Ami Choi, Christopher Merchant +14
The Nancy Grace Roman Space Telescope will conduct several community-driven surveys using its Wide Field Instrument (WFI), which contains 18 Teledyne H4RG-10 near-infrared detector…
Nancy Grace Roman Space Telescope Wide Field Instrument: Bright Point Source Saturation Response and Persistence Properties from Thermal-Vacuum Testing
Dana R. Louie, Robert F. Wilson, Thomas Barclay +19
The Nancy Grace Roman Space Telescope's Wide Field Instrument (WFI) will observe hundreds of thousands of bright stars across its Core Community Surveys, particularly in the dense…
Nonlinearity in H4RG-10 Near-Infrared Detectors at Elevated Temperatures: Characterization and Data-Driven Correction Method
Ryusei Hamada, Gregory Mosby, Shota Miyazaki +5
We report a newly identified nonlinearity in H4RG-10 near-infrared detectors operating under moderately elevated-temperature conditions (114 K). This component, that potentially ar…
Simple Improved Reference Subtraction for H4RG, H2RG, and H1RG Near-infrared Array Detectors
Bernard J. Rauscher, Dale J. Fixsen, Gregory Mosby
Teledyne's H4RG, H2RG, and H1RG near-infrared array detectors provide reference pixels embedded in their data streams. Although they do not respond to light, the reference pixels e…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
The Pandora SmallSat: A Low-Cost, High Impact Mission to Study Exoplanets and Their Host Stars
Thomas Barclay, Elisa V. Quintana, Knicole Colón +19
The Pandora SmallSat is a NASA flight project aimed at studying the atmospheres of exoplanets -- planets orbiting stars outside our Solar System. Pandora will provide the first dat…
The Pandora SmallSat: Multiwavelength Characterization of Exoplanets and their Host Stars
Elisa V. Quintana, Knicole D. Colón, Gregory Mosby +24
Pandora is a SmallSat mission designed to study the atmospheres of exoplanets, and was selected as part of NASA's Astrophysics Pioneers Program. Transmission spectroscopy of transi…
Properties and characteristics of the WFIRST H4RG-10 detectors
Gregory Mosby, Bernard J. Rauscher, Chris Bennett +16
The Wide-Field Infrared Survey Telescope (WFIRST) will answer fundamental questions about the evolution of dark energy over time and expand the catalog of known exoplanets into new…
Principal Component Analysis of Up-the-ramp Sampled IR Array Data
Bernard J. Rauscher, Richard G. Arendt, D. J. Fixsen +3
We describe the results of principal component analysis (PCA) of up-the-ramp sampled IR array data from the HST WFC3 IR, JWST NIRSpec, and prototype WFIRST WFI detectors. These sys…
