The Light-Only Liquid Xenon (LoLX) experiment is designed to study scintillation light and characterize the performance of silicon photomultipliers (SiPMs) in a liquid xenon (LXe) medium. To ensure the SiPMs are functioning properly, it is necessary to verify that all of them are submerged. LoLX therefore requires a LXe level sensor. Outgassing requirements, cryogenic temperature, space...
A neutron star is one of the densest objects in the universe. Therefore, studying and understanding binary neutron star mergers can help us to understand the behaviour of ultra-dense matter also used to describe nuclear matter in extreme conditions. During those stellar events, most of the gravitational potential energy is transferred to neutrinos that escape the neutron-rich ejecta, and some...
In many environments, such as the early universe or stars, finite temperature effects modify the properties of particles, including their dispersion relations. In particular, the Standard Model photon acquires an effective mass. Furthermore, collective plasma excitations give rise to a longitudinal mode which is absent in vacuum. The key object to compute the effective in-medium mass of both...
