Dark Matter that Interacts with Baryons: Experimental Limits on the Interaction Cross-section for 27 Atomic Nuclei, and Resultant Constraints on the Particle Properties
David A. Neufeld, Daniel J. Brach-Neufeld
To constrain the properties of dark matter (DM) that interacts with nucleons, we have conducted an experimental search for any anomalous heating of ordinary baryonic matter at 77 K…
Dark Matter that Interacts with Baryons: Density Distribution within the Earth and New Constraints on the Interaction Cross-section
David A. Neufeld, Glennys R. Farrar, Christopher F. McKee
For dark matter (DM) particles with masses in the 0.6 - 6 m_p range, we set stringent constraints on the interaction cross-sections for scattering with ordinary baryonic matter. Th…
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 $…
Discovery of Hydrogen Fluoride in the Cloverleaf Quasar at z = 2.56
R. R. Monje, T. G. Phillips, R. Peng +3
We report the first detection of hydrogen fluoride (HF) toward a high redshift quasar. Using the Caltech Submillimeter Observatory (CSO) we detect the HF J = 1 - 0 transition in ab…
Discovery of Water Vapor in the High-Redshift Quasar APM 08279+5255 at Z=3.91
D. C. Lis, D. A. Neufeld, T. G. Phillips +2
We report a detection of the excited 220-211 rotational transition of para-H2O in APM 08279+5255 using the IRAM Plateau de Bure interferometer. At z = 3.91, this is the highest-red…
