Cosmology and Dark Matter searches: Cosmology and Dark Matter searches

The CRESST experiment is among the most sensitive direct detection dark matter experiments searching for particles in the sub-GeV region. The experiment is based on crystals operated at cryogenic temperatures. The simultaneous read-out of the total deposited energy by collecting phonons and scintillation light allows the separation of signal and background events. The cryogenic technology will...
Direct-detection searches have traditionally focused on Weakly Interacting Massive Particles (WIMPs) with masses above the proton (about 1 GeV/c^2). However, many natural dark-matter candidates have masses below the proton and are invisible in traditional WIMP searches. In this talk, I will provide an overview of the search for particle dark matter with masses between about 1 meV/c^2 to 1...
The Lorentz-invariance of Maxwell's equations governing electromagnetism in a vacuum is well-established. This is immediately apparent when these laws can be rephrased in terms of the field strength tensor, four-potential and four-current. Obtaining a manifestly covariant formulation of Maxwell's equations in a medium is however non-trivial. Subtleties related to the Lorentz-invariance of the...
The ΛCDM model is currently our best description of the universe. However, the model does not
come without fault as discrepancies between theory and observation have emerged. Bulk viscosity
has been proposed as a possible extension to the ΛCDM model as to account for these mismatches.
We review two alternative scenarios for the study of relativistic dissipative hydrodynamics applied
to...
