The Potential of the SPHEREx Mission for Characterizing Polycyclic Aromatic Hydrocarbon 3.3 μm Emission in Nearby Galaxies

Edward Zhang, Andreas L. Faisst, Brendan Crill +18

Together with gas, stars, and supermassive black holes, dust is crucial in stellar and galaxy evolution. Hence, understanding galaxies' dust properties across cosmic time is critic…

Simulating Spectral Confusion in SPHEREx Photometry and Redshifts

Zhaoyu Huai, James J. Bock, Yun-Ting Cheng +12

We model the impact of source confusion on photometry and the resulting spectrophotometric redshifts for SPHEREx, a NASA Medium-Class Explorer that is carrying out an all-sky near-…

Accuracy of Stellar Mass-to-light Ratios of Nearby Galaxies in the Near-Infrared

Taehyun Kim, Minjin Kim, Luis C. Ho +12

Future satellite missions are expected to perform all-sky surveys, thus providing the entire sky near-infrared spectral data and consequently opening a new window to investigate th…
