A bestiary of low-level electrical artifacts in SPHEREx flight data
Candice M. Fazar, Michael Zemcov, C. Darren Dowell +3
SPHEREx, NASA's all-sky spectrophotometric survey mission, maps the sky in 102 spectral channels from 0.75 um to 5.0 um at 6.15'' resolution from low-Earth orbit using a custom rea…
Image persistence flagging for SPHEREx
Candice Fazar, C. Darren Dowell, Brendan P. Crill +3
Image persistence in HAWAII-2RG HgCdTe detectors has been observed by multiple parties. Also known as latent signal, this effect occurs when sensor images following an illumination…
Observations of Atmospheric Helium and Oxygen with SPHEREx
Howard Hui, Chi Nguyen, Ryan Wills +20
We present measurements of near-infrared (NIR) terrestrial airglow produced by helium and oxygen in the exosphere as observed by SPHEREx. Using eight months of survey data obtained…
Spectral response of SPHEREx
Howard Hui, Jamie Bock, Samuel Condon +31
The Spectro Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) is conducting the first all-sky near infrared spectral survey spanning 0.…
The SPHEREx Satellite Mission
James J. Bock, Asad M. Aboobaker, Joseph Adamo +111
SPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.7…
Optimized Observation Sequencing in Low-Earth Orbit with the SPHEREx Survey Planning Software
Sean Bryan, James Bock, Thomas Burk +23
SPHEREx is a NASA infrared astronomy mission that launched on March 12th, 2025 and is operating successfully in low-Earth orbit (LEO). The mission is currently observing the entire…
Cryogenic Focus Measurement System for a Wide-Field Infrared Space Telescope
Samuel S. Condon, Stephen Padin, James Bock +4
We describe a technique for measuring focus errors in a cryogenic, wide-field, near-infrared space telescope. The measurements are made with a collimator looking through a large va…
Noise Reduction Methods for Large-scale Intensity-mapping Measurements with Infrared Detector Arrays
Grigory Heaton, Walter Cook, James Bock +10
Intensity mapping observations measure galaxy clustering fluctuations from spectral-spatial maps, requiring stable noise properties on large angular scales. We have developed speci…
