About Me

I'm Tommaso Marchetti, a PhD student in astronomy at Leiden Observatory (The Netherlands). My main research involves hypervelocity stars: stars with such a high velocity that they are not gravitationally bound to our Galaxy, the Milky Way, but they are flying away from it. These stars are amongst the fastest objects in the Universe! Find more about hypervelocity stars here.

I graduated from the University of Rome "La Sapienza" in September 2015 with a Master of Science Degree in Astronomy and Astrophysics. For my thesis I worked with Prof. Paolo de Bernardis on the optimization of optical components for LSPE, a stratospheric balloon-borne experiment aimed at measuring the B-modes of CMB polarization. One chapter of my thesis resulted in a publication that can be found here.

Since October 2015 I'm doing a PhD at Leiden Observatory, in the Netherlands, under the supervision of Dr. Elena Maria Rossi. The goal of my PhD is to find hypervelocity stars in the Gaia catalogue.
