Speaker: Dr.Atreya Acharyya (University of Alabama) Astronomy at the Highest Photon Energies Abstract: Most astronomical telescopes observe thermal radiation. However, this does not include the most energetic gamma-rays photons, produced by large particle accelerators in space, which also act as tracers for cosmic-ray sources. While gamma-rays can be observed using space-based detectors, their relatively small

Speaker: Dr. Leandro Beraldo e Silva (University of Michigan) Title: Co-formation of the Milky Way's thin and thick discs Abstract: Thin disc stars are younger than thick disc stars on average, and some models predict the thin disc to start forming only after the thick disc has formed, around 10 Gyr ago. According to these
