The number of eclipsing binary and multiple systems observed by large, high quality photometric surveys is downright staggering: with OGLE setting the standard, Kepler and TESS leading the way in photometric…
I will discuss the possibility that dark matter is made of weakly interacting, very light scalar particles, briefly reviewing the strong theoretical motivations of this proposal. In a scenario where non-gravitational…
The SM Higgs sector is subject to two fine-tunings, manifesting in the hierarchy problem and the metastability of the electroweak vacuum. I will explain why these tunings, which were long believed to be independent,…
By analyzing the gravitational lensing effects of stars and planets in our galaxy, and other massive distant galaxies, microlensing provides unique insights into phenomena that are otherwise difficult to observe. In…
After reviewing the motivation and challenges connected with the dRGT theory of ghost-free massive gravity, we discuss our recent progress in understanding non-linear dynamics of this model. In spherical symmetry,…
