We present a new numerical code that solves the general relativistic magneto-hydrodynamical (GRMHD) equations coupled to the Einstein equations for the evolution of a dynamical spacetime within a conformally-flat approximation. This code has been developed with the main objective of studying astrophysical scenarios in which both, high magnetic fields and strong gravitational fields appear, such as the magneto-rotational collapse of stellar cores, the collapsar model of GRBs, and the evolution…

The Fully Constrained Formulation (FCF) of General Relativity is a novel framework introduced as an alternative to the hyperbolic formulations traditionally used in numerical relativity. The FCF
Gravitational Wave Signatures of Magnetohydrodynamically Driven Core-collapse Supernova Explosions
By performing a series of two-dimensional, special relativistic magnetohydrodynamic (MHD) simulations, we study signatures of gravitational waves (GWs) in the MHD-driven core-collapse supernovae. In

Three Dimensional Magneto Hydrodynamical Simulations of Gravitational Collapse of a 15Msun Star
We introduce our newly developed two different, three dimensional magneto hydrodynamical codes in detail. One of our codes is written in the Newtonian limit (NMHD) and the other is in the fully

Relativistic numerical model for close neutron-star binaries.
The evidence that general relativistic effects may cause the stars to individually collapse into black holes prior to merging and the strong fields cause the last stable orbit to occur at a larger separation distance and lower frequency than previously estimated is discussed.
