چکیده

We use the energy-momentum complexes of Landau and Lifshitz and Papapetrou to obtain the energy distribution in Melvin’s magnetic universe. For this space-time we find that these definitions of energy give the same and convincing results. The energy distribution obtained here is the same as we obtained earlier for the same space-time using the energy-momentum complex of Einstein. These results uphold the usefulness of the energy-momentum complexes. Typeset using REVTEX ∗E-mail: [email protected]

Energy Associated with Schwarzchild Black Hole in a Magnetic Universe

In this paper we obtain the energy distribution associated with the Ernst spacetime (geometry describing Schwarzschild black hole in Melvin’s magnetic universe) in Einstein’s prescription. The first term is the rest-mass energy of the Schwarzschild black hole, the second term is the special relativistic value for the energy of the uniform magnetic field and the remaining terms in the expression...

Cosmic strings in axionic-dilatonic gravity

We first consider local cosmic strings in dilaton-axion gravity and show that they are singular solutions. Then we take a supermassive Higgs limit and present expressions for the fields at far distances from the core by applying a Pecci-Quinn and a duality transformation to the dilatonic Melvin’s magnetic universe.

Ultra - high energy cosmic rays : are they isotropic ?

From the analysis of AGASA data above 4 × 10 eV, we show that the ultra-high energy cosmic rays flux is neither purely isotropic, nor reflects the expected anisotropy from a pure source distribution that maps large scale structure in the local universe. The arrival distribution seems to be the result of a mixture of fluxes (e.g., dark matter halo plus large scale structure) or the superposition...
