Abstract: Atomically thin crystals form a vast family of 2D quantum materials, with only a few well studied. Engineered structures like stacked 2D crystals and moiré superlattices offer exceptionally rich and highly tunable platforms for exploring...

Cosmological observables, from the Lyman-alpha forest to the Milky Way substructure, offer unique avenues for probing dark matter and neutrino sectors. Moreover, they often reveal anomalies and tensions that could signal new physics. I will review...

The commonly observed Type Ia supernovae likely occur when one star in a binary undergoes a sudden detonation triggered by the transfer of mass from a closely orbiting companion. Due to the short orbital period of 5-10 minutes of many explosion...

Abstract: Classical" accretion disks are geometrically thin, radiatively efficient and mechanized by turbulent viscosity. Yet, many observational and theoretical issues challenge this standard model, suggesting that we are missing essential-but...

Fast Radio Bursts are a recently discovered phenomenon consisting of brief (typically few millisecond) bursts of radio waves coming from far outside our Milky Way galaxy, indeed from cosmological distances. Their origin is unknown. I will review...

Abstract: It is well known that the study and observation of core collapse Supernovae provide powerful tools to probe possible scenarios of physics beyond the Standard Model (SM). In this seminar, I will provide an overview of the mechanisms...
