What specific era of cosmic history is SPHEREx primarily designed to study via its spectral focus?
Answer
The epoch of reionization.
SPHEREx focuses on the near-infrared band to capture the redshifted glow from the epoch of reionization, when the first stars and galaxies began illuminating the neutral hydrogen fog.
