Propagation in the atmosphere of ultrahigh-energy charmed hadrons
Propagation the atmosphere ultrahigh-energy charmed hadrons
2011/1/13
Charmed mesons may be produced when a primary cosmic ray or the leading hadron in an air shower collide with an atmospheric nucleon. At energies \ge 10^8 GeV their decay length becomes larger than 10 ...
A possible approach to three-dimensional cosmic-ray propagation in the Galaxy IV. Electrons and electron-induced gamma-rays
three-dimensional cosmic-ray propagation the Galaxy IV. Electrons
2011/1/11
Based on the diffusion-halo model for cosmic-ray (CR) propagation, including stochastic reacceleration due to collisions with hydromagnetic turbulence, we study the behavior of the electron component ...
The propagation of thermonuclear flame in presupernovae Ia is considered. Front parameters are obtained, some speculations on front stability are presented.
Constraints on cosmic-ray propagation models from a global Bayesian analysis
astroparticle physics—diffusion—methods statistical—cosmic rays—ISM general—Galaxy: general
2010/11/9
Research in many areas of modern physics such as, e.g., indirect searches for dark matter and particle acceleration in SNR shocks, rely heavily on studies of cosmic rays (CRs) and associated diffuse e...
How to use molecular clouds to study the propagation of cosmic rays in the Galaxy
cosmic rays:origin and propagation gamma rays molecular clouds
2010/11/12
Observations of molecular clouds in the gamma ray domain provide us with a tool to study the distribution of cosmic rays in the Galaxy. This is because cosmic rays can penetrate molecular clouds, unde...
Propagation of the burst of radiation in expanding and recombining Universe: Thomson scattering
radiation expanding recombining Universe
2011/1/10
Within the framework of a flat cosmological model a propagation of an instantaneous burst of nonpolarized isotropic radiation is considered from the moment of its beginning at some initial redshift z0...
Cosmic ray propagation time scales: lessons from radioactive nuclei and positron data
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Phenomenology (hep-ph)
2011/1/4
We take a fresh look at high energy radioactive nuclei data reported in the 90's and at the positron data recently reported by PAMELA. Our aim is to study the model independent implications of these d...
(Ultra-)High Energy Muon Neutrino Propagation through the Earth and Induced Muon Energy Distribution near the One Cubic Kilometer Detector
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Experiment (hep-ex)
2010/12/28
We calculate high and (ultra-)high energy upward-going muon neutrino propagation through the Earth and the induced muon energy distribution near the one cubic kilometer detector using the Monte Carlo ...
Propagation of an Earth-directed coronal mass ejection in three dimensions
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP) Plasma Physics (physics.plasm-ph) Space Physics (physics.space-ph)
2010/12/23
Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood. Whil...
Numerical versus analytical accuracy of the formulas for light propagation
Numerical versus analytical light propagation
2010/3/19
Numerical integration of the differential equations of light propagation in the Schwarzschild metric shows that in some situations relevant for practical observations the well-known post-Newtonian sol...
This paper reviews recent progress in the research on the
initiation and propagation of CMEs. In the initiation part, several trigger
mechanisms are discussed; in the propagation part, the observati...
