TIME Commissioning Observations: I. Mapping Dust and Molecular Gas in the Sgr A Molecular Cloud Complex at the Galactic Center
Selina F. Yang, Sophie M. McAtee, Benjamin J. Vaughan +24
We present the processing of an observation of Sagittarius A (Sgr A) with the Tomographic Ionized-carbon Mapping Experiment (TIME), part of the 2021-2022 commissioning run to verif…
The SPHEREx Sky Simulator: Science Data Modeling for the First All-Sky Near-Infrared Spectral Survey
Brendan P. Crill, Yoonsoo P. Bach, Sean A. Bryan +29
We describe the SPHEREx Sky Simulator, a software tool designed to model science data for NASA's SPHEREx mission that will carry out a series of all-sky spectrophotometric surveys…
Mapping Galactic Dust Emission and Extinction with HI, HII, and H
Yun-Ting Cheng, Brandon S. Hensley, Tzu-Ching Chang +1
Neutral hydrogen (HI) emission closely traces the dust column density at high Galactic latitudes and is thus a powerful tool for predicting dust extinction. However, the relation b…
The relative constraining power of the high- 21-cm dipole and monopole signals
Jordan Mirocha, Chris Anderson, Tzu-Ching Chang +2
The 21-cm background is a promising probe of early star formation and black hole activity. While a slew of experiments on the ground seek to detect the 21-cm monopole and spatial f…
