Neutral and charged matter in equilibrium with black holes
Neutral charged matter equilibrium black holes
2011/10/14
We study the conditions of a possible static equilibrium between spherically symmetric, electrically charged or neutral black holes and ambient matter. The following kinds of matter are considered: (1...
The charged dust solution of Ruban -- matching to Reissner--Nordström and shell crossings
shell crossings even half cycle oscillation minimal size
2011/10/14
The maximally extended Reissner--Nordstr\"om (RN) manifold with $e^2 < m^2$ begs for attaching a material source to it that would preserve the infinite chain of asymptotically flat regions and evolve ...
Dark Matter and Charged Exotic Dust
Dark matter charged dust isothermal Lane-Emden equation
2011/10/18
The density profiles of dark matter halos are often modeled by an approximate solution to the isothermal Lane-Emden equation with suitable boundary conditions at the origin. It is shown here that such...

The interior structure black holes
2011/1/13
This paper extends to the case of charged rotating black holes the conformally stationary, axisymmetric, separable solutions presented for uncharged rotating black holes in a companion paper. In the p...
Anisotropic Inflation from Charged Scalar Fields
Anisotropic Inflation Charged Scalar Fields
2011/1/11
We consider models of inflation with $U(1)$ gauge fields and charged scalar fields including symmetry breaking potential, chaotic inflation and hybrid inflation. We show that there exist attractor sol...
The Relation Between Charged Particles and Muons With Threshold Energy 1 GeV in Extensive Air Showers Registered at the Yakutsk EAS Array
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
Characteristics of the muon component in EAS are analyzed together with their fluctuations. The aim of this analysis -- a comparison of experimental data with computational results obtained within fra...
Gravitational Charged Perfect Fluid Collapse in Friedmann Universe Models
Electric field Gravitational collapse Cosmological constant Friedmann models
2010/3/18
This paper is devoted to study the gravitational charged perfect fluid collapse in the Friedmann universe models with cosmological constant. For this purpose, we assume that the electromagnetic field ...
Production of tidal-charged black holes at the Large Hadron Collider
Tidal-charged black hole Large Hadron Collider
2010/3/18
Tidal-charged black hole solutions localized on a three-brane in the five-dimensional gravity scenario of Randall and Sundrum have been known for some time. The solutions have been used to study the d...

Response of a Balloon-Borne Omnidirectional Detector to the Atmospheric Secondary Charged Cosmic Radiation at a place of 11.5 GV Geomagnetic Cut-Off。
ESTIMATION OF ELECTRON-IMPACT LINE WIDTHS FOR SINGLY-, DOUBLY- AND TRIPLY-CHARGED VANADIUM IONS
ELECTRON-IMPACT LINE DOUBLY- SINGLY- TRIPLY-CHARGED VANADIUM IONS
2009/3/26
In this paper we present the electron-impact widths for 28 transitions
of singly-, doubly-, and triply- ionized vanadium estimated by using the
modified semiempirical method. The electron-impact wid...
