I study various topics in Theoretical Astrophysics, with a focus on:
- High-Energy Astrophysics,
- Neutrino and Cosmic-Ray Astrophysics,
- Relativistic Plasma Astrophysics.
A significant fraction of my time is devoted to leading the Israeli side of the Israeli/US UV satellite mission ULTRASAT, which is aiming at revolutionizing the study of astronomical transients:
Some exciting recent news on these subjects
- IceCube detects extra-terrestrial neutrinos (see ViewPoint for a general intro and references).
- AMS-02 results support a secondary origin for cosmic-ray positrons (PRL).
