Lorenzo Sironi


I am a NASA Einstein Post-Doctoral Fellow in the Institute for Theory and Computation (ITC) at the Harvard-Smithsonian Center for Astrophysics. I obtained my Ph.D. in 2011 in the Department of Astrophysical Sciences at Princeton University, under the supervision of Prof. Anatoly Spitkovsky.

In my research, I investigate the origin of nonthermal emission from Pulsar Wind Nebulae, AGN jets and gamma-ray bursts. It is still a mystery how these objects can accelerate particles up to the highly nonthermal energies required to explain the observed spectra, that typically extend from the radio up to the gamma-ray band. By means of first-principles large-scale plasma simulations, I investigate particle acceleration in relativistic flows, unveiling the nature of astrophysical nonthermal sources.
