Dr. Paz Beniamini is an astrophysicist. His research domain is theoretical high energy astrophysics, which deals with some of the most extreme environments in nature, in which particles can be accelerated to within a fraction of the speed of light and the magnetic fields may be a hundred trillion times greater than those on Earth. Paz’s research focuses on Gamma ray bursts, fast radio bursts, magnetars, binary neutron stars and formation channels of heavy elements in the Universe. Paz holds a BSc, MSc and PhD in Physics from the Hebrew University. After completing his PhD work in 2016 he was a postdoctoral researcher at the Institut d’Astrophysique de Paris, at the George Washington University and at the California institute of technology (Caltech). Paz joined the Open University of Israel as a senior lecturer in 2021.
