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...
Symmetries play a crucial role in both quantum field theory and
quantum many-body systems on the lattice. One key topological
feature that a global symmetry can have is a "('t Hooft) anomaly".
But how exactly should an anomaly be defined? In this...
I will present a combination of three observational
techniques—astrometry, radial velocity, and direct imaging—to
discover, weigh, and characterize massive exoplanets and brown
dwarfs. Only a few exoplanets have both measured masses (from
radial...
Black hole perturbation theory captures a few important effects
in the dynamics of binary mergers, such as tidal deformations and
the decay of ringdown modes. It also describes the physics of the
photon ring. However, extracting qualitative results...
