The SPHEREx Instrument: Calibration, testing and performance measurements of the NIR 2 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…
The SPHEREx Ices Investigation: An Overview
Gary J. Melnick, Joseph L. Hora, Matthew L. N. Ashby +26
SPHEREx is a NASA mission designed to perform an all-sky spectroscopic survey in the 0.75 - 5 m wavelength range. Its primary science objectives are to investigate: (1) inflati…
Cosmology with voids from the Nancy Grace Roman Space Telescope
Giovanni Verza, Giulia Degni, Alice Pisani +7
We provide an accurate forecast of the expected constraining power from the main void statistics -- the void size function and the void-galaxy cross-correlation function -- to be m…
Mapping Galactic Dust Emission and Extinction with HI, HII, and H
Yun-Ting Cheng, Brandon S. Hensley, Tzu-Ching Chang +1
Neutral hydrogen (HI) emission closely traces the dust column density at high Galactic latitudes and is thus a powerful tool for predicting dust extinction. However, the relation b…
