Emerging Technologies for Astrophysics Missions: Workshop Summary Report
Brendan P Crill, Nicholas Siegler, Dan Sirbu +3
NASA's Astrophysics Division convened the Emerging Technologies for Astrophysics Missions (ETAM) Workshop in March 2025 at the Ames Research Center in Silicon Valley, California. T…
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…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Comparing the Near-infrared Spectral Energy Distributions from Different Stellar Population Synthesis Models with SPHEREx Observations
Jeong Hwan Lee, Minjin Kim, Woong-Seob Jeong +17
While stellar population synthesis (SPS) models have been widely used for spectral analysis in optical wavelengths, their characteristics remain uncertain in the near-infrared (NIR…
A UV-to-Near-infrared QSO Composite Spectrum from the SPHEREx All-Sky Survey
Minjin Kim, Yongjung Kim, Woong-Seob Jeong +19
We present a composite spectrum of type 1 SDSS QSOs (median ), constructed using SPHEREx spectrophotometric data and covering a rest-frame wavelength…
Tracing the Boundary of the South Atlantic Anomaly Region with SPHEREx Transient Flagging Rates
Chi H. Nguyen, James Bock, Sean Bryan +10
The NASA SPHEREx satellite was launched in 03/2025 to survey the full sky between 0.75 - 5.0 um. The image processing of SPHEREx H2RG detectors includes real-time flagging of trans…
SPHEREx 0.75 to 5 m Spectra for a Sequence of Nearby Brown Dwarfs
Zafar Rustamkulov, J. Kirkpatrick, Rachel Akeson +21
The SPHEREx all-sky survey has now measured the R40-100 infrared spectra of thousands of nearby brown dwarfs in the chemically rich 0.75-5 m range. The survey's wide spect…
The SPHEREx View of Galaxy Clusters: A Simulation-based Validation of the Forced Photometry Pipeline for Extended Sources
Hyeonguk Bahk, Ho Seong Hwang, Lindsey Bleem +12
We present a simulation-driven assessment of the performance of the SPHEREx pipeline for galaxy cluster science, focusing on photometry, source blending, survey depth, and photomet…
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…
The SPHEREx Instrument: Calibration, testing and performance measurements of the NIR spectroscopic surveyor from the laboratory to in-orbit commissioning
Phil M. Korngut, James J. Bock, Samuel Condon +90
The SPHEREx near-infrared space telescope is an all-sky spectroscopic survey mission launched on March 12th, 2025 UTC. In addition to providing the community with a spectral databa…
SPHEREx Wide-Field Infrared Spectral Mapping of Interstellar Ices and Polycyclic Aromatic Hydrocarbons
Joseph L. Hora, Jinyoung K. Noh, Gary J. Melnick +32
We present some of the first infrared spectral maps acquired by SPHEREx. These maps, which to our knowledge are the largest of their type ever compiled in the near-infrared, reveal…
