A new first-order formulation of the Einstein equations exploiting analogies with electrodynamics
H. Olivares, I. M. Peshkov, E. R. Most +2
The Einstein and Maxwell equations are both systems of hyperbolic equations which need to satisfy a set of elliptic constraints throughout evolution. However, while electrodynamics…
Modeling general-relativistic plasmas with collisionless moments and dissipative two-fluid magnetohydrodynamics
Elias R. Most, Jorge Noronha, Alexander A. Philippov
Relativistic plasmas are central to the study of black hole accretion, jet physics, neutron star mergers, and compact object magnetospheres. Despite the need to accurately capture…
Quasi-universal behaviour of the threshold mass in unequal-mass, spinning binary neutron-star mergers
Samuel D. Tootle, L. Jens Papenfort, Elias R. Most +1
The lifetime of the remnant produced by the merger of two neutron stars can provide a wealth of information on the equation of state of nuclear matter and on the processes leading…
Dissipative Magnetohydrodynamics for Non-Resistive Relativistic Plasmas
Elias R. Most, Jorge Noronha
Based on a 14-moment closure for non-resistive (general-) relativistic viscous plasmas, we describe a new numerical scheme that is able to handle all first-order dissipative effect…
Impact of the nuclear symmetry energy on the post-merger phase of a binary neutron star coalescence
Elias R. Most, Carolyn A. Raithel
The nuclear symmetry energy plays a key role in determining the equation of state of dense, neutron-rich matter, which governs the properties of both terrestrial nuclear matter as…
Projecting the likely importance of weak-interaction-driven bulk viscosity in neutron star mergers
Elias R. Most, Steven P. Harris, Christopher Plumberg +6
In this work, we estimate how much bulk viscosity driven by Urca processes is likely to affect the gravitational wave signal of a neutron star coalescence. In the late inspiral, we…
On accretion disks formed in MHD simulations of black hole-neutron star mergers with accurate microphysics
Elias R. Most, L. Jens Papenfort, Samuel D. Tootle +1
Remnant accretion disks formed in compact object mergers are an important ingredient in the understanding of electromagnetic afterglows of multi-messenger gravitational-wave events…
Scaling of Small-Scale Dynamo Properties in the Rayleigh-Taylor Instability
Valentin Skoutnev, Elias R. Most, Amitava Bhattacharjee +1
We derive scaling relations based on free-fall and isotropy assumptions for the kinematic small-scale dynamo growth rate and amplification factor over the course of the mixing, sat…
Weak Alfvénic turbulence in relativistic plasmas. Part 1. Dynamical equations and basic dynamics of interacting resonant triads
J. M. TenBarge, B. Ripperda, A. Chernoglazov +6
Alfvén wave collisions are the primary building blocks of the non-relativistic turbulence that permeates the heliosphere and low-to-moderate energy astrophysical systems. However,…
Weak Alfvénic turbulence in relativistic plasmas II: Current sheets and dissipation
B. Ripperda, J. F. Mahlmann, A. Chernoglazov +6
Alfvén waves as excited in black hole accretion disks and neutron star magnetospheres are the building blocks of turbulence in relativistic, magnetized plasmas. A large reservoir o…
A new public code for initial data of unequal-mass, spinning compact-object binaries
L. Jens Papenfort, Samuel D. Tootle, Philippe Grandclément +2
The construction of constraint-satisfying initial data is an essential element for the numerical exploration of the dynamics of compact-object binaries. While several codes have be…
GW170817 and GW190814: tension on the maximum mass
Antonios Nathanail, Elias R. Most, Luciano Rezzolla
The detection of the binary events GW170817 and GW190814 has provided invaluable constraints on the maximum mass of nonrotating configurations of neutron stars, . H…
