Light Hidden Sectors and the Hubble Tension
The inference of the present expansion rate from the Cosmic Microwave Background and other early-time probes (assuming standard cosmology) is in significant tension with several direct measurements of the same...

Neutrinos in Cosmology after Planck: What are their masses, properties, and relationship with the Hubble tension?
Neutrinos are a key (although implicit) ingredient of the standard cosmological model, LambdaCDM. Firstly, neutrinos directly participate in neutron freeze out during BBN, and secondly, they represent 40% of the...

Recent insights on SN1987a: implications for BSM phenomenology
New results from astrophysics have radically changed our understanding of neutron stars and supernovae, specifically SN1987A. In this talk, I will describe some of these results and the implications they...

Analyticity and unitarity's offspring: anomalous dimensions and the space of EFTs
In the first part of the talk I will present how to compute anomalous dimensions of EFT operators using on-shell scattering amplitudes. The method is used to compute some two...

The Neutrino Magnetic Moment Portal: Cosmology, Astrophysics, and Direct Detection
We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard...

Stochasticity and Axion Direct Detection
The ultralight axion-like particle remains a compelling dark matter candidate. If such a particle constitutes dark matter, it will generate a classical field that oscillates at the compton frequency but...

More Axions from Strings
The axion solution to the strong CP problem also provides a natural dark matter candidate. If the Peccei-Quinn symmetry has ever been restored after inflation, topological defects of the axion...
