General relativity and extreme-mass-ratio binaries

General relativity and extreme-mass-ratio binaries

General relativity and extreme-mass-ratio binaries In this talk, I will give a broad and largely non-technical overview of general relativity and strong gravitational two-body systems, from the status of their theoretical modeling to their observation via...
Looking for Partially-Massless Gravity

Looking for Partially-Massless Gravity

Looking for Partially-Massless Gravity I will summarize the status of the search for a unitary theory of partially-massless (PM) spin-two field interacting with Gravity in arbitrary dimensions. The talk is based on the paper...
Heavy Dynamical Axions

Heavy Dynamical Axions

Heavy Dynamical Axions In this talk, I present a model with an enlarged color sector which solves the strong CP problem via new massless fermions. QCD color is unified with another non-Abelian group with a large confinement scale. The spontaneous breaking of the...
Outflows from young stars

Outflows from young stars

Outflows from young stars Outflows are ubiquitous in star-forming regions. They are associated with accretion events and trace the rich chemistry produced by shocks and heating surrounding protostars. Protostellar outflows yield a turbulent feedback that can be of...
