Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey: Report of a Community Workshop Examining Extragalactic, Galactic, Stellar and Planetary Science
Olivier Doré, Michael W. Werner, Matt Ashby +65
SPHEREx is a proposed SMEX mission selected for Phase A. SPHEREx will carry out the first all-sky spectral survey and provide for every 6.2" pixel a spectra between 0.75 and 4.18 $…
Dust May Be More Rare Than Expected in Metal Poor Galaxies
David B. Fisher, Alberto D. Bolatto, Rodrigo Herrera-Camus +7
'Normal' galaxies observed at z>6, when the Universe was <1 billion years old, thus far show no evidence of the cold dust that accompanies star formation in the local Universe, whe…
A high-dispersion molecular gas component in nearby galaxies
Anahi Caldu-Primo, Andreas Schruba, Fabian Walter +5
We present a comprehensive study of the velocity dispersion of the atomic (HI) and molecular (H2) gas components in the disks (R < R25) of a sample of 12 nearby spiral galaxies wit…
Investigating the presence of 500 um submillimeter excess emission in local star forming galaxies
Allison Kirkpatrick, Daniela Calzetti, Maud Galametz +10
Submillimeter excess emission has been reported at 500 microns in a handful of local galaxies, and previous studies suggest that it could be correlated with metal abundance. We inv…
Towards A Removal of Temperature Dependencies from Abundance Determinations
Kevin V. Croxall, J. D. Smith, B. R. Brandl +16
The metal content of a galaxy is a key property for distinguishing between viable galaxy evolutionary scenarios, and it strongly influences many of the physical processes in the in…
Andromeda's Dust
B. T. Draine, G. Aniano, Oliver Krause +10
Spitzer Space Telescope and Herschel Space Observatory imaging of M31 is used, with a physical dust model, to construct maps of dust surface density, dust-to-gas ratio, starlight h…
