Nir Shaviv is a full professor at the Racah Institute of Physics in the Hebrew University of Jerusalem. His main research interests revolve around the following topics:
- The behaviour of very luminous astrophysical objects, so luminous that their radiation pressure should have blown themselves apart (but they don't!). This topic is related to various objects, including classical nova eruptions, very massive stars, supernova precurors, and high rate accretion discs.
- High energy astrophysics (e.g., the diffusion of cosmic rays in the Milky Way, the PAMELA anomaly).
- Cosmic Ray effects on climate, on time scales ranging from 100's of millions of years, to the 11-year solar cycle.
Most of his work is theoretical, meaning that he builds models and then tries to compare them to data collected by other people.
