Ameliorating the Courant-Friedrichs-Lewy condition in spherical coordinates: A double FFT filter method for general relativistic MHD in dynamical spacetimes
Liwei Ji, Vassilios Mewes, Yosef Zlochower +5
Numerical simulations of merging compact objects and their remnants form the theoretical foundation for gravitational wave and multi-messenger astronomy. While Cartesian-coordinate…
Addition of tabulated equation of state and neutrino leakage support to IllinoisGRMHD
Leonardo R. Werneck, Zachariah B. Etienne, Ariadna Murguia-Berthier +11
We have added support for realistic, microphysical, finite-temperature equations of state (EOS) and neutrino physics via a leakage scheme to IllinoisGRMHD, an open-source GRMHD cod…
Next-generation HPC models for future rotorcraft applications
Nicoletta Sanguini, Tommaso Benacchio, Daniele Malacrida +4
Rotorcraft technologies pose great scientific and industrial challenges for numerical computing. As available computational resources approach the exascale, finer scales and theref…
Handing off the outcome of binary neutron star mergers for accurate and long-term post-merger simulations
Federico G. Lopez Armengol, Zachariah B. Etienne, Scott C. Noble +20
We perform binary neutron star (BNS) merger simulations in full dynamical general relativity with IllinoisGRMHD, on a Cartesian grid with adaptive-mesh refinement. After the remnan…
Implementing a new recovery scheme for primitive variables in the general relativistic magnetohydrodynamic code Spritz
Jay V. Kalinani, Riccardo Ciolfi, Wolfgang Kastaun +3
General relativistic magnetohydrodynamic (GRMHD) simulations represent a fundamental tool to probe various underlying mechanisms at play during binary neutron star (BNS) and neutro…
HARM3D+NUC: A new method for simulating the post-merger phase of binary neutron star mergers with GRMHD, tabulated EOS and neutrino leakage
Ariadna Murguia-Berthier, Scott C. Noble, Luke F. Roberts +25
The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component p…

Federico Cipolletta, Jay Vijay Kalinani, Edoardo Giangrandi +4
We here present a new version of the publicly available general relativistic magnetohydrodynamic (GRMHD) code , which now includes an approximate neutrino leakage…
Numerical relativity in spherical coordinates: A new dynamical spacetime and general relativistic MHD evolution framework for the Einstein Toolkit
Vassilios Mewes, Yosef Zlochower, Manuela Campanelli +4
We present SphericalNR, a new framework for the publicly available Einstein Toolkit that numerically solves the Einstein field equations coupled to the equations of general relativ…
Spritz: a new fully general-relativistic magnetohydrodynamic code
Federico Cipolletta, Jay Vijay Kalinani, Bruno Giacomazzo +1
The new era of multimessenger astrophysics requires the capability of studying different aspects of the evolution of compact objects. In particular, the merger of neutron star bina…

Federico Cipolletta, Christian Cherubini, Simonetta Filippi +2
We compute the binding energy and angular momentum of a test-particle at the last stable circular orbit (LSO) on the equatorial plane around a general relativistic, rotating neutro…
Effects of Orthogonal Rotating Electric Fields on Electrospinning Process
Marco Lauricella, Federico Cipolletta, Giuseppe Pontrelli +2
Electrospinning is a nanotechnology process whereby an external electric field is used to accelerate and stretch a charged polymer jet, so as to produce fibers with nanoscale diame…

Federico Cipolletta, Christian Cherubini, Simonetta Filippi +2
We construct equilibrium configurations of uniformly rotating neutron stars for selected relativistic mean-field nuclear matter equations of state (EOS). We compute in particular t…
Collapse of spherical charged anisotropic fluid spacetimes
F. Cipolletta, R. Giambò
A class of spherical collapsing exact solutions with electromagnetic charge is derived. This class of solutions -- in general anisotropic -- contains however as a particular case t…
