About

Sunny Vagnozzi was brought up in Italy, where he obtained his Bachelor's degree in Physics in 2012 from the University of Trento. He did his Master's studies in Theoretical Particle Physics at Imperial College, London (as an Erasmus Scholar) and at the University of Melbourne, between 2012 and 2014. He spent most of 2015 as a visiting research student at the Niels Bohr Institute, Copenhagen, and as a frequent visitor at CP3-Origins, Odense.

Sunny moved to Stockholm in September 2015 to start his PhD at the Oskar Klein Centre at Stockholm University, and NORDITA, under the supervision of Katherine Freese and Lars Bergström. He also works under the supervision of Shirley Ho (Carnegie Mellon University), and is an official visitor at the Michigan Center for Theoretical Physics, University of Michigan.

Much of Sunny's past research focus has been devoted to studying models of dark matter. Particularly, models which go beyond the collisionless cold dark matter paradigm, with emphasis on their small-scale phenomenology, direct detection prospects, and impact on astrophysical bodies such as the Sun. Another past theme of research has been the study of modified theories of gravity, with the aim of unifying inflation and the late-time cosmic acceleration, and dark matter.

Sunny's current research interests are concerned with large-scale structure (LSS) of the Universe. He is analyzing data from LSS surveys, which contain a wealth of information for both particle physics and cosmology. Sunny is exploiting the data to extract information about the dynamics of inflation (in particular to detect signs of primordial non-Gaussianity, which could rule out the simplest single-field slow-roll inflationary models), but is also using the data to investigate about neutrino masses and their hierarchy. He is a member of the Italian Physical Society.
