The temperature and polarization anisotropies of the cosmic microwave background (CMB) have been used to set constraints on decaying dark matter models down to keV masses. In this talk, I will discuss recent work to…
The LIGO-Virgo-KAGRA Collaboration has detected nearly one hundred black-hole mergers in its first three observing runs and is finding several candidate mergers every week during its ongoing fourth run. These mergers…
The averaged null energy condition, or ANEC, is a fundamental bound on negative energy in quantum field theory. It has applications ranging from black holes to quantum information to the 3D Ising model,…
