Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
Estimation of compact binary coalescense rates short gamma-ray redshift measurements
2010/12/21
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...
Inflation of Bianchi type-$\Rmnum{7}_0$ Universe with Dirac Field in Einstein-Cartan theory
Einstein-Cartan theory Bianchi type-V II0 inflation Dirac field
2010/12/21
We discuss the Bianchi type-V II0 cosmology with Dirac field in Einstein-Cartan the-ory. We obtain the equations of Dirac field and gravitational field in Einstein-Cartan theory. We find a Bianchi typ...
Modified general relativity as a model for quantum gravitational collapse
Modified general relativity model quantum gravitational collapse
2010/12/20
We study a class of Hamiltonian deformations of the massless Einstein-Klein-Gordon system in spherical symmetry for which the Dirac constraint algebra closes. The system may be regarded as providing e...

The phase boundary for the chiral transition in (2+1)-flavor QCD at small values of the chemical potential
phase boundary for the chiral transition (2+1)-flavor QCD small values
2011/1/14
We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light
quark chemical potential. We show that for small values of the chemical potential the curvature

Modeling Gravitational Recoil Using Numerical Relativity
Gravitational Recoil Numerical Relativity
2010/12/20
We review the developments in modeling gravitational recoil from merging black-hole binaries and introduce a new set of 20 simulations to test our previously proposed empirical formula for the recoil....

2011/1/6
We make a frequentist analysis of the parameter space of minimal supergravity (mSUGRA), in which, as well as the gaugino and scalar soft supersymmetry-breaking parameters being universal.
Dynamical effects of General Relativity on the satellite-to-satellite range and range-rate in the GRACE mission
Dynamical effects of General Relativity satellite-to-satellite range range-rate GRACE mission
2010/12/20
In this Letter, by reconstructing the Om diagnostic and the deceleration parameter q from
the latest Union2 Type Ia supernova sample with and without the systematic error along with
the baryon acous...
Relativistic Beaming in AdS/CFT
Relativistic AdS/CFT
2010/12/21
We propose a mechanism of `beaming' the backreaction of a relativistic source in the bulk of AdS towards the boundary. Using this beaming mechanism to estimate the energy distribution from
radiation ...

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 equati...
Scalar-isoscalar states, gravitational form factors, and dimension-2 condensates in a large-Nc Regge approach
s meson scalar-isoscalar states large-Nc Regge models pion and nucleon gravitational form factors
2011/1/10
Scalar-isoscalar states (JPC = 0++) are analyzed within the large-Nc Regge approach. We find that the lightest f0(600) scalar-isoscalar state fits very well into the pattern of the radial Regge trajec...

Collective flow long-range correlations relativistic heavy ion collisions
2011/1/7
Making use of recently released data on dihadron correlations by the STAR collaboration, I analyze the long-range (“ridge-like”) part of these data and show that the dependence on both transverse mome...

2010/12/20
In our Prague paper [1], we predicted that the Cooper pairs will respond to a gravitational (GR) wave di erently from the ions of the ionic lattice of a superconductor (SC), because there exists a glo...
