This article reports on the results of novel, extremely high-resolution simulations of the general relativistic magnetohydrodynamics (MHD) of neutron star mergers, focussing on angular momentum transport due to the MHD turbulence. The authors show that the Kelvin-Helmholtz instability at merger amplifies the magnetic energy to of the thermal energy.

Dark matter is usually assumed to couple to the Standard Model only weakly. However, the authors propose a simple model of heavy new fermions which carry strong color charge and form stable bound states. These bound states can act as dark matter and appear consistent with current cosmological and experimental limits.
