- August 2017 - A pair of projects based on NASA/IRTF SpeX spectroscopy have revealed some new and unexpected findings, including a cometary origin for the red excess seen in the HR4796A system (Lisse et al., 2017), and a close-in carbon-rich circumstellar belt in the young HD 36546 A-star system. These results suggest a rich scientific harvest awaits SPHEREx because of its ability to provide sensitive spectra at similar wavelengths.
- June 2016 - A wide range of science opportunities enabled for the community by SPHEREx are described in the white paper resulting from February's workshop: see Doré et al., 2016. The science topics are wide-ranging, and include extragalactic, galactic, and solar system investigations.
- June 2016 - The ability of SPHEREx to measure very accurate redshifts is described in detail in a new paper from the SPHEREx team. See Stickley et al., 2016.
- June 2016. The SPHEREx sampling algorithm is described in a paper
recently accepted by the Journal of Astronomical Instrumentation. See
Zemcov et al., 2016 for more.
- January 2016. The SPHEREx team described the updated mission concept in six presentations at the Kissimmee AAS meeting:
An All-Sky Spectral Survey (Bock; [PDF]),
Instrument Design and Implementation (Korngut; [PDF]),
Probing the Physics of Inflation (Doré ; [PDF]),
The Origin and Evolution of Interstellar and Protoplanetary Biogenic Molecules: A Comprehensive Survey of Interstellar Ices (Melnick; [PDF]),
Understanding the Origin and Evolution of Galaxies through the Extragalactic Background Light (Zemcov; [PDF]), and
Science Opportunities for the Astronomical Community (Cooray; [PDF]).

An analysis of fluctuations on arcminute scales in deep HST/ACS and WFC3 mosaics, extending the technique to shorter wavelengths than previously explored at these depths. Presents new predictions for the strength of the signal from galaxies at redshifts beyond z=8.

A detailed discussion of a general observing strategy for an all-sky survey, including spacecraft and instrument optimization, constraints, and a scheduling algorithm. This strategy will be used by the SPHEREx mission to achieve its all-sky and and deep-sky surveys.
