Machine Learning for Conservative-to-Primitive in Relativistic Hydrodynamics

The numerical solution of relativistic hydrodynamics equations in conservative form requires root-finding algorithms that invert the conservative-to-primitive variables map. These algorithms employ the equation of state of the fluid and […]

High-Order Multipole and Binary Love Number Universal Relations

Using a data set of approximately 2 million phenomenological equations of state consistent with observational constraints, we construct new equation-of-state-insensitive universal relations that exist between the multipolar tidal deformability parameters […]

Long-term GRHMD simulation of magnetic field in isolated neutron stars

Strong magnetic fields play an important role in powering the emission of neutron stars. Nevertheless a full understanding of the interior configuration of the field remains elusive. In this work, […]

Large and massive neutron stars: implications for the sound speed in dense QCD

The NASA telescope NICER has recently measured x-ray emissions from the heaviest of the precisely known two-solar mass neutron stars, PSR J0740+6620. Analysis of the data [Miller et al., Astrophys. […]

Where they split, they entangle: A (collective) neutrino story

Neutrinos do not experience strong or electromagnetic interactions, and are therefore by far the most feebly interacting among all the known particles in the universe. Nevertheless, there are situations where […]
