Antenna characterization for the HIRAX experiment

The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) aims to improve constraints on the dark energy equation of state through measurements of large-scale structure at high redshift ($0.8$700MHz. Noise temperature measurements of the HIRAX

Chasing Hot Stuff in the Universe with Cool Stuff on Earth: Numerical and Deep Learning Methods for Dark Matter Annihilation

Autor: List, Florian

There is ample evidence for the existence of dark matter (DM) from cosmological observations. However, despite zealous efforts by the experimental particle physics community over the past decades, no confirmed detection of a DM particle has been repo
