Transition Radiation from the Neutrino-Photon Interaction in Matter
Transition Radiation the Neutrino-Photon Interaction Matter
2012/2/23
We show that, because of their effective electromagnetic interaction in matter, transition radiation is emitted whenever neutrinos goes across the boundary between two media with different indices of ...
Shower Center of Gravity and Hadronic Interaction Characteristics
Shower Center Gravity Hadronic Interaction Characteristics
2012/2/23
Equations for the center of gravity of the shower originated by high energy proton in the atmosphere are written and, within certain simplifications, solved for the case of logarithmically decreasing ...
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
2011/10/20
We report a spectroscopic analysis of an EIT wave event that occurred in active region 11081 on 2010 June 12 and was associated with an M2.0 class flare. The wave propagated near circularly. The south...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
We study the change in cosmic-ray pressure, the change in cosmic-ray density, and the level of cosmic-ray induced heating via Alfven-wave damping when cosmic rays move from a hot ionized plasma to a c...
The Stellar Archeology of the M33 Disk: Recent Star-Forming History and Constraints on the Timing of an Interaction with M31
galaxies evolution — galaxies spiral — galaxies
2011/8/24
Images recorded with MegaCam are used to investigate the recent star-forming history (SFH) of the Local Group Sc galaxy M33. The properties of the stellar disk change near R = 8 kpc. Within this radiu...
The Interaction of High-Speed Turbulence with Flames: Turbulent Flame Speed
Turbulent premixed combustion, Turbulence, Flamelet, Turbulent flame speed, Hydrogen-air combustion
2011/9/14
Direct numerical simulations of the interaction of a premixed flame with driven, subsonic, homogeneous, isotropic,Kolmogorov-type turbulence in an unconfined system are used to study the mechanisms de...
The Interaction of High-Speed Turbulence with Flames: Global Properties and Internal Flame Structure
Turbulent premixed combustion, Turbulence, Flamelet, Flame structure, Hydrogen
2011/9/14
We study the dynamics and properties of a turbulent flame, formed in the presence of subsonic, high-speed, homogeneous,isotropic Kolmogorov-type turbulence in an unconfined system. Direct numerical si...
On the interaction of a thin, supersonic shell with a molecular cloud
supersonic shell with molecular cloud
2011/1/10
Molecular clouds (MCs) are stellar nurseries, however, formation of stars within MCs depends on the ambient physical conditions. MCs, over a free-fall time are exposed to numerous dynamical phenomena,...
Gamma-rays from SS~433 and its interaction with the W50 nebula
Gamma-rays observations — binaries general — X-rays binaries — stars
2010/11/12
We investigate the production of gamma-rays in the inner regions of SS 433 and in its interaction between its jets and the W50 nebula. We estimate the VHE emission that can be generated within the jet...
Tails of the Unexpected: The Interaction of an Isothermal Shell with a Cloud
hydrodynamics – ISM bubbles – planetary nebulae general – planetary nebulae individual NGC 7293
2010/11/15
A new mechanism for the formation of cometary tails behind dense clouds or globules is discussed. Numerical hydrodynamical models show that when a dense shell of swept-up matter overruns a cloud, mate...
Numerical simulation of the interaction between solar granules and small-scale magnetic fields
Numerical simulation interaction between solar granules small-scale magnetic fields
2010/11/12
We have carried out numerical simulation based on the equations of radiation magnetohydrodynamics to study the interaction of solar granules and small-scale magnetic fields in photospheric regions wit...
On the alpha formalism for the common envelope interaction
the alpha formalism the common envelope interaction
2011/1/10
The {\alpha}-formalism is a common way to parametrize the common envelope interaction between a giant star and a more compact companion. The {\alpha} parameter describes the fraction of orbital energy...

High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/5
We present the first three-dimensional simulations of the evolution of a microquasar jet inside the binary-star system. The aim is to study the interaction of these jets with the stellar wind from a m...
