On Monday, November 18, 2024, at 12:00 c.t., the next date of our physics colloquium will take place this winter semester.
Dr. Elisa Pueschel, astrophysicist at the Astronomical Institute, talks about "DARK MATTER SEARCHES WITH VERY-HIGH-ENERGY GAMMA RAYS".
Dark matter makes up an estimated 85% of the matter in the universe, yet its
nature is mysterious. While visible matter interacts readily with light, dark
matter does not. We are only confident that dark matter feels the force of
gravity. However, it is possible that dark matter has further interactions with
visible matter, which would lead to the production of high-energy photons. This
emitted light, beyond the range of visible light, would help us understand what
dark matter is made of and how it interacts with visible matter. I will describe
efforts to chase light from dark matter using ground-based imaging atmospheric
Cherenkov telescopes, including the current generation VERITAS instrument and
the upcoming Dark100 array.
