Despite overwhelming evidence for dark matter in our universe, its true nature remains a mystery. In the search for direct detection, detectors using liquid xenon are currently leading in sensitivity. However, these experiments are increasingly limited by self-induced backgrounds, particularly the emanation of radon from detector materials. To address this challenge, a novel radon mitigation...

One of the fundamental characteristics of blazars is their central black hole mass. In absence of broad emission lines, which is the case for the majority of blazars (i.e. BL Lacs), the black holes mass is estimated by analysing the luminosity of the host galaxies. To date, these galaxies are thought to be massive and luminous ellipticals, but the data sample supporting this conclusion is...
