For more than twenty years, it has been argued that the Weyl anomaly of quantum electrodynamics sources cosmological magnetic fields in the early universe. If true, this would be a natural way to produce the seed magnetic fields of our universe within the Standard Model. In this talk, I will examine this long-standing claim and show that there is actually no production of coherent magnetic...
Ground-based gamma-ray telescopes based on the imaging atmospheric Cherenkov technique (IACTs) are one of our best tools to access the very-high-energy (few tens of GeV and above) gamma-ray sky. Consequently, these instruments have the capability to offer observations in this particular energy band that may hint at the answers of some of the most pressing questions in Cosmology, like that of...
In the context of dark matter (DM) searches, it is crucial to quantify and reduce theoretical uncertainties affecting predictions of observables that depend on the DM velocity distribution, including event rates in direct searches, velocity-dependent annihilation rates, and microlensing event rates for DM compact objects. The well-known Eddington inversion formalism for the self- consistent...
