Scientists ditch approximations,begin modeling universe with Einstein’s full theory of General Relativity
Scientists ditch approximations modeling universe Einstein’s full theory General Relativity
2016/7/4
Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of...
The Jet in the Galactic Center: An Ideal Laboratory for Magnetohydrodynamics and General Relativity
the Galactic Center An Ideal Laboratory Magnetohydrodynamics
2011/1/11
In this paper we review and discuss some of the intriguing properties of the Galactic Center supermassive black hole candidate Sgr A*. Of all possible black hole sources, the event horizon of Sgr A*, ...
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...
Probing modifications of General Relativity using current cosmological observations
General Relativity integrated Sachs-Wolfe weak lensing
2010/3/9
We test General Relativity (GR) using current cosmological data: the cosmic microwave background (CMB) from WMAP5 (Komatsu et al. 2009), the integrated Sachs-Wolfe (ISW) effect from the cross-correla...
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...
The Robertson-Walker Metric in a Pseudo-Complex General Relativity
Walker metric energy-momentum
2010/3/18
We investigate the consequences of the pseudo-complex General Relativity within a pseudo-complexified Roberston-Walker metric. A contribution to the energy-momentum tensor arises, which corresponds to...
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...
