Measurement of Cosmic Ray antiproton/proton flux ratio at TeV energies with ARGO-YBJ
Extensive Air Showers Cosmic Rays Moon shadow antiproton ARGO-YBJ
2011/10/10
Cosmic ray antiprotons provide an important probe for the study of cosmic-ray propagation in the interstellar space and to investigate the existence of Galactic dark matter. The ARGO-YBJ experiment, l...
Comparison of Energies Between Eruptive Phenomena and Magnetic Field in AR 10930
Energies Eruptive Phenomena Magnetic Field
2011/1/11
We present a study comparing the energy carried away by a coronal mass ejection (CME) and the radiative energy loss in associated flare plasma, with the decrease in magnetic free energy during a relea...
A comparative study of the neutrino-nucleon cross section at ultra high energies
comparative study neutrino-nucleon cross section
2010/11/16
The high energy neutrino cross section is a crucial ingredient in the calculation of the event rate in high energy neutrino telescopes. Currently there are several approaches which predict different b...
A recent progress in the study of $\gamma$-ray jets is reviewed, with a focus on some theoretical interpretations of the VHE emission from M87, and possibly other misaligned blazars; the connection be...
Masses and envelope binding energies of primary stars at the onset of a common envelope
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We present basic properties of primary stars that initiate a common envelope (CE) in a binary, while on the giant branch. We use the population-synthesis code described in Politano et al. (2010) and f...
