Hyperbolicity of scalar-tensor theories of gravity
Marcelo Salgado, David Martinez-del Rio, Miguel Alcubierre +1
Two first order strongly hyperbolic formulations of scalar-tensor theories of gravity (STT) allowing nonminimal couplings (Jordan frame) are presented along the lines of the 3+1 de…
Multipole expansions for energy and momenta carried by gravitational waves
Milton Ruiz, Miguel Alcubierre, Dario Nunez +1
We present expressions for the energy, linear momentum and angular momentum carried away from an isolated system by gravitational radiation based on spin-weighted spherical harmoni…
Regularization of spherical and axisymmetric evolution codes in numerical relativity
Milton Ruiz, Miguel Alcubierre, Dario Nunez
Several interesting astrophysical phenomena are symmetric with respect to the rotation axis, like the head-on collision of compact bodies, the collapse and/or accretion of fields w…
Testing excision techniques for dynamical 3D black hole evolutions
Miguel Alcubierre, Bernd Bruegmann, Peter Diener +4
We perform both distorted black hole evolutions and binary black hole head on collisions and compare the results of using a full grid to results obtained by excising the black hole…
Constraint and gauge shocks in one-dimensional numerical relativity
Bernd Reimann, Miguel Alcubierre, José A. González +1
We study how different types of blow-ups can occur in systems of hyperbolic evolution equations of the type found in general relativity. In particular, we discuss two independent c…
On a debate about cosmic censor violation
Miguel Alcubierre, Jose A. Gonzalez, Marcelo Salgado +1
We review the arguments and counter arguments about the recent proposal for generic censorship violation. In particular the argument made in gr-qc/0405050 against our proposal for…
