Avishay Gal-Yam

Senior Scientist, Department of Particle Physics and Astrophysics

Weizmann Institute of Science




I head the experimental astrophysics group at the department of particle physics and astrophysics at the Weizmann Institute of Science in Israel. Our research projects are presented in more detail below. Additional related activity takes place at the Benoziyo Center for Astrophysics.

At this time, we are looking for graduate students and postdocs.

If you are interested, please contact me at avishay.gal-yam _ at _ weizmann.ac.il, call my office on 972-8-9342063, or drop by (if you're around) - my office is 277 Weismann (Physics).
