Giacomo Fragione graduated in Astronomy and Astrophysics, magna cum laude, under the supervision of Prof. Alessandro Melchiorri working on the data from the European Planck satellite. In 2014-2016, he was a fellow of the joint Ph.D. “Astronomy, Astrophysics and Space Sciences” of the University of Rome “La Sapienza” and the University of Rome Tor Vergata. His thesis, entitled “Hypervelocity Stars as Tools for Galactic Astrophysics”, was developed under the supervision of Prof. Roberto Capuzzo-Dolcetta. In 2017-2019, he was jointly a Fellow of the Israel Academy of Sciences and Humanities and an Arskin Postdoctoral Fellow at the Hebrew University of Jerusalem. He was a CIERA Postdoctoral Fellow from 2019-2020.
His research focuses on the dynamical evolution of dense stellar environments as globular clusters and galactic nuclei. He has been actively working on mergers of black holes and neutron stars in star clusters and in hierarchical configurations as a source of gravitational waves, relevant for the LIGO-Virgo collaboration and the upcoming LISA mission. He also studies the elusive population of intermediate mass black holes to fill the gap in the black hole-mass desert. Other interests include the characteristics and origin of planetary systems in binary and triple stars.
