Small-scale dark matter structures provide an important window into primordial density fluctuations and the microphysical properties of dark matter. Deviations from the standard LCDM model can significantly alter the…
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…
