Stationary, Axisymmetric Neutron Stars with Meridional Circulation in General Relativity
Stationary Axisymmetric Neutron Stars Meridional Circulation General Relativity
2010/12/20
We present the first stationary, axisymmetric neutron star models with meridional circulation in general relativity. For that purpose, we developed GRNS, a new code based on a fixed point iteration.
Complementarity of Kinematics and Geometry in General Relativity Theory
Complementarity of Kinematics Geometry General Relativity Theory
2010/12/20
Relations between kinematics, geometry and law of reference frame motion are considered. We show, that kinematical tensors define geometry up to a space functiona arbitrariness when integrability cond...
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 DFT++ method implemented with projector augmented waves: Electronic structure of SrVO$_3$ and the Mott Transition in Ca$_{2-x}$Sr$_{x}$RuO$_4$
General DFT++ method implemented projector augmented waves Mott Transition
2010/11/24
The realistic description of correlated electron systems has taken an important step forward a few years ago as the combination of density functional methods and the dynamical mean-field theory was co...
Starburst radio galaxies: general properties, evolutionary histories and triggering
galaxies active – galaxies jets – galaxies starburst – galaxies:interactions
2010/11/12
In this paper we discuss the results of a programme of spectral synthesis modelling of
a sample of starburst radio galaxies in the context of scenarios for the triggering of the
activity and the evo...
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...
Criterion of unitary similarity for upper triangular matrices in general position
upper triangular matrices general position
2010/11/8
Each square complex matrix is unitarily similar to an upper triangular matrix with diagonal entries in any prescribed order. Let A and B be upper triangular n-by-n matrices that (i) are not similar to...
Finite size effects on the Poynting-Robertson effect: a fully general relativistic treatment
Poynting-Robertson general relativistic treatment
2010/12/21
Even since the first discovery of Poynting and Robertson, the radiation source has been treated
as merely a point. Even in a very few studies where the size of the source has been taken
into account...
Stability of general-relativistic accretion disks
Stability general-relativistic accretion disks
2010/12/21
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 ...
In this paper, local Tb theorems are studied both in the doubling and non-doubling situation. We prove a local Tb theorem for the class of upper doubling measures. With such general measures, scale i...
An effective approach to the problem of time: general features and examples

2010/12/20
The effective approach to quantum dynamics allows a reformulation of the Dirac quantization
procedure for constrained systems in terms of an infinite-dimensional constrained system of classical type....

General heavenly equation anti-self-dual gravity
2010/12/21
We show that the general heavenly equation, suggested recently by Doubrov and Ferapontov [1], governs anti-self-dual (ASD) gravity. We derive ASD Ricci-flat vacuum metric governed by the general heave...

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...
