Title
Dark Matter Search with MAGIC Telescopes
Speaker
Dr. Stefan Fröse (Institute of Physics, Academia Sinica)Abstract
Dark matter candidates like WIMPs may annihilate in regions of high density, such as dwarf galaxies, producing gamma rays that traverse the cosmos to reach Earth. The MAGIC telescopes detect these gamma rays through Cherenkov light produced when high-energy photons interact with Earth's atmosphere.
This talk provides an overview of the MAGIC telescopes and their role in gamma-ray astronomy, as well as present novel analysis methods developed for studying the Coma Berenices dwarf spheroidal galaxy. This work extends beyond traditional energy-only analyses by implementing a three-dimensional approach incorporating spatial dimensions. Key innovations include improved background modeling and new statistical methods for dark matter searches.
The three-dimensional search for DM-induces gamma rays significantly outperforms previous MAGIC studies in sensitivity, with methods made available through the open-source TITRATE Python package.
