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…
Spontaneous creation of circularly polarized photons in chiral astrophysical systems
Adrian del Rio, Nicolas Sanchis-Gual, Vassilios Mewes +3
This work establishes a relation between chiral anomalies in curved spacetimes and the radiative content of the gravitational field. In particular, we show that a flux of circularl…
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…
Numerical relativity in spherical coordinates with the Einstein Toolkit
Vassilios Mewes, Yosef Zlochower, Manuela Campanelli +3
Numerical relativity codes that do not make assumptions on spatial symmetries most commonly adopt Cartesian coordinates. While these coordinates have many attractive features, sphe…
Quasistationary solutions of self-gravitating scalar fields around collapsing stars
Nicolas Sanchis-Gual, Juan Carlos Degollado, Pedro J. Montero +2
Recent work has shown that scalar fields around black holes can form long-lived, quasistationary configurations surviving for cosmological timescales. With this requirement, scalar…
Numerical relativity simulations of thick accretion disks around tilted Kerr black holes
Vassilios Mewes, José A. Font, Filippo Galeazzi +2
In this work we present 3D numerical relativity simulations of thick accretion disks around tilted Kerr BH. We investigate the evolution of three different initial disk models with…
Measuring the black hole spin direction in 3D Cartesian numerical relativity simulations
Vassilios Mewes, José A. Font, Pedro J. Montero
We show that the so-called flat-space rotational Killing vector method for measuring the Cartesian components of a black hole spin can be derived from the surface integral of Weinb…
