The nEXO experiment is being designed to search for neutrino-less double beta decay ($0\nu\beta\beta$) in a 5000 kg liquid xenon time projection chamber (TPC) enriched to the isotope xenon-136. nEXO's > 10$^{28}$ year sensitivity reach to the $0\nu\beta\beta$ half-life requires extremely low backgrounds from external sources. Backgrounds are dealt with in part by surrounding the TPC with an...
The properties of low mass dark matter halos and subhalos, less than 10^9 solar masses, heavily depend on the particle nature of dark matter. Strong gravitational lensing provides a direct probe of these low mass halos. The relative brightnesses of lensed images (flux ratios) in quadruply-imaged quasars (quads) are sensitive to low-mass dark matter structure, and can be used to constrain dark...
Radon assays are an effective way to determine the amount of radon in a particular area or substance in question, and therefore determine the state of it. The assay technique that is currently being performed has been used for several years, and has further developed and improved to collect data for a large number of vessels past its original application. By performing assays, it allows us to...
A mysterious excess in diffuse far-ultraviolet (FUV) background radiation was observed by the Galaxy Evolution Explorer (GALEX) orbiting telescope with bandwidth 1344–1786 Å. This radiation remains strong even at high galactic latitude where young blue stars, the only known source of UV photons, do not exist. Scattered light from UV sources in the galactic disk is also unable to account for...
