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…

CIBER galaxy cross-correlations reveal a bright, low-redshift NIR background

Richard M. Feder, Grigory Heaton, James J. Bock +7

We perform the first tomographic analysis of near-IR extragalactic background light (EBL) anisotropies, cross-correlating CIBER 1.1 and 1.8 m imager data with photometric galaxy…

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…

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…
