One way to test the theory of inflation is to measure the imprint of inflationary ripples on the large-scale structure (LSS) of galaxies. SPHEREx will probe the statistical distribution of inflationary ripples by measuring the large-scale 3D distribution of galaxies.

The SPHEREx observing strategy naturally generates a wide+deep map at each ecliptic pole (the southern map will be shifted to avoid the LMC). Both maps will enable unique measurements of spatial fluctuations in the extragalactic background light (EBL) which will lead to new insights into the origin and history of galaxy formation.

SPHEREx will be a game changer in resolving long-standing questions about the amount and evolution of key biogenic molecules (

) throughout all phases of star and planetary formation.

The First All-Sky Spectral Survey

SPHEREx will observe the entire sky multiple times during its planned two-year mission. Its overlapping scan strategy will obtain a minimum of four 0.75--5.0 micron spectra at every point along the ecliptic, with much greater redundancy in the deep survey fields at the North and South ecliptic poles. SPHEREx will achieve point source sensitivities magnitudes deeper than 2MASS in every SPHEREx spectral element.

Instrument

SPHEREx implements a simple and robust design that maximizes spectral throughput and efficiency. SPHEREx achieves this with no moving parts except for one-time deployments of a sunshield and aperture cover.
