  Binary neutron star mergers using a discontinuous Galerkin-finite difference hybrid method

  We present a discontinuous Galerkin-finite difference hybrid scheme that allows high-order shock capturing with the discontinuous Galerkin method for general relativistic magnetohydrodynamics in dynamical spacetimes. We present several optimizations and […]

  Energy-dependent and Energy-integrated Two-moment General-relativistic Neutrino Transport Simulations of a Hypermassive Neutron Star

  We compare two-moment-based energy-dependent and three variants of energy-integrated neutrino transport general-relativistic magnetohydrodynamics simulations of a hypermassive neutron star. To study the impacts due to the choice of the neutrino […]

  Performance-portable Binary Neutron Star Mergers with AthenaK

  We introduce an extension to the AthenaK code for general-relativistic magnetohydrodynamics (GRMHD) in dynamical spacetimes using a 3+1 conservative Eulerian formulation. Like the fixed-spacetime GRMHD solver, we use standard finite-volume […]

  Baryon Number Violation: From Nuclear Matrix Elements to BSM Physics

  Processes that violate baryon number, most notably proton decay and nn¯ transitions, are promising probes of physics beyond the Standard Model (BSM) needed to understand the lack of antimatter in […]

  Revisiting 𝐶 and 𝐶⁢𝑃 violation in 𝜂→𝜋+⁢𝜋−⁢𝜋0 decay

  The decay η→π+π−π0 is an ideal process in which to study flavor-conserving C and CP violation beyond the Standard Model. We deduce the C- and CP-odd quark operators that contribute […]
