Magnetorotational instabilities in solids: Application to neutron-star crusts
Arthur G. Suvorov, Thomas Celora, Kostas D. Kokkotas
The magnetorotational instability can generate strong, turbulent substructure within magnetized shear flows. The efficacy of the mechanism as a function of microphysical aspects of…
Action based approach to dissipative relativistic fluid systems
G. L. Comer, N. Andersson, T. Celora +1
We develop an action principle for a relativistic two-fluid system with dissipation. The specific constituents of the model - which serves as a proof of principle - are particles a…
Impact of magnetic field gradients on the development of the MRI: Applications to binary neutron star mergers and proto-planetary disks
T. Celora, C. Palenzuela, D. Viganò +1
The magneto-rotational instability (MRI) is widely believed to play a central role in generating large-scale, poloidal magnetic fields during binary neutron star mergers. However,…
Higher-level large-eddy filtering strategy for general relativistic fluid simulations
Thomas Celora, Nils Andersson, Ian Hawke +2
Nonlinear simulations of neutron star mergers are complicated by the need to represent turbulent dynamics. As we cannot (yet) perform simulations that resolve accurately both the g…
Covariant approach to relativistic large-eddy simulations: Lagrangian filtering
T. Celora, M. J. Hatton, I. Hawke +1
We present a proof-of-principle implementation of the first fully covariant filtering scheme applied to relativistic fluid turbulence. The filtering is performed with respect to sp…
