Sunny Vagnozzi is an Italian cosmologist. He is an assistant professor at the University of Trento.[1]
Vagnozzi is known for his contributions at the interface of cosmology, particle physics, and astrophysics, with a primary focus on determining the fundamental nature of dark matter and dark energy. He has been awarded the Buchalter Cosmology Prize for his work on dark energy,[2] and is the recipient of the 2023 SIGRAV Prize.[3] Additionally, he is an editor of the journal Physics of the Dark Universe.[4]
Education
[edit]Vagnozzi earned a Bachelor of Science in Physics from the University of Trento in 2012, followed by a Master of Science in Physics from the University of Melbourne in 2014. Later in 2019, he completed a Ph.D. in Theoretical Physics from Stockholm University.[5]
Career
[edit]Following his PhD, Vagnozzi joined the Kavli Institute for Cosmology at the University of Cambridge as a Newton-Kavli Fellow.[6] In 2022, he returned to the University of Trento, where he has been serving as an assistant professor.[1]
Media coverage
[edit]Vagnozzi's work has been highlighted by various news websites and science magazines, including Science, Science News, Quanta Magazine, New Scientist, National Geographic (Poland), Esquire and Forbes.[7][8][9][10][11][12][13]
Research
[edit]Vagnozzi has worked on a broad array of problems at the interface of cosmology and astroparticle physics. His work has contributed to investigating the nature of dark matter and dark energy,[14][15] testing cosmic inflation,[16][17] determining the shape of the universe,[18] understanding the origins of cosmic tensions (including the Hubble tension),[19][15] using black hole observations to test gravity and fundamental physics,[20] and searching for signatures of neutrino masses in cosmological observations.[21] Additionally, his research has identified new ways for detecting dark energy in experiments on Earth,[22] and has proposed new techniques for testing gravity and searching for fifth forces by analyzing asteroid trajectories.[23]
