93. SPHEREx Instrument Performance and Early In-Orbit Results

Howard Hui (Caltech)

The Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) is a NASA Medium Explorer mission designed to carry out the first all-sky spectral survey in the near-infrared (0.75–5 μm) with spectral resolutions ranging from R ~ 41 to 135.
In this talk, we present an overview of SPHEREx’s instrument performance, drawing from the first 40 days of...

68. Intensity Mapping with SPHEREx Deep-Field Near-Infrared Maps at 102 Wavelengths

Shuang-Shuang Chen (California Institute of Technology)

I will present the SPHEREx map-making pipeline, a key component of our effort in intensity mapping. SPHEREx is an all-sky near-infrared spectral survey that was launched in early March. One of its three main science goals is to explore the origin and evolution of galaxies and probe the epoch of reionization (EoR) through a deep survey mapping large-scale structure. SPHEREx will produce two...

84. Mock skies for SPHEREx auto- and cross-correlation analyses

Jordan Mirocha (JPL/Caltech)

SPHEREx, NASA's latest space telescope (launched March 11th, 2025!), will soon begin its survey of the entire sky in 102 near-infrared spectral channels. Intensity mapping -- including auto- and cross-spectrum analyses -- will be focused on a 100 deg^2 deep field centered on the north ecliptic pole, but shallower maps will exist over the whole sky enabling cross-correlations with surveys...
