General Relativistic Magnetohydrodynamic Bondi--Hoyle Accretion
General Relativistic Magnetohydrodynamic Bondi--Hoyle Accretion
2010/11/15
In this paper we present a fully relativistic study of axisymmetric magnetohydrodynamic Bondi{
Hoyle accretion onto a moving Kerr black hole. The equations of general relativistic magnetohydrodynamic...
Stability of general-relativistic accretion disks
Stability general-relativistic accretion disks
2010/11/15
Self-gravitating relativistic disks around black holes can form as transient structures in a number of astrophysical scenarios such as binary neutron star and black hole-neutron star coalescences, as ...
Dynamical effects of General Relativity on the satellite-to-satellite range and range-rate in the GRACE mission
Experimental studies of gravity Experimental tests of gravitational theories
2010/11/16
We numerically investigate the impact of the General Theory of Relativity (GTR) on the
satellite-to-satellite range ρ and range-rate ρ˙ of the twin GRACE A/B spacecrafts through their dynamical equat...
Complementarity of Weak Lensing and Peculiar Velocity Measurements in Testing General Relativity
Complementarity of Weak Lensing Peculiar Velocity Measurements General Relativity
2010/11/12
We explore the complementarity of weak lensing and galaxy peculiar velocity measurements to
better constrain modifications to General Relativity. We find no evidence for deviations from GR on cosmolo...
General Relativistic Magnetohydrodynamic and Monte Carlo Modeling of Sagittarius A*
accretion disc black hole Galactic Center magnetohydrodynamics
2010/11/11
We present results of models of the physical space and parameters of the accretion disk of Sagittarius A*, as well as simulations of its emergent spectrum.This begins with HARM, a 2D general relativis...
We present an introduction to mass and angular momentum in General Relativity. After briefly reviewing energy-momentum for matter fields, first in the flat Minkowski case (Special Relativity) and then...
Spacetime Brout-Englert-Higgs effect in General Relativity interacting with p-brane matter
Brout-Englert-Higgs p-brane matter
2010/3/19
We review the manifestation of the Brout-Englert-Higgs effect in general relativity interacting with point-like and extended objects (p-branes including string for p=1 and membrane for p=2), which man...
