Anisotropy and chemical composition of ultra-high energy cosmic rays using arrival directions measured by the Pierre Auger Observatory
(Institute of Physics - IOPBristol, 2011-06)
The Pierre Auger Collaboration has reported evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > Eth = 5.5 × 1019 eV. These show a correlation with the distribution of ...
Radio detection of cosmic ray air showers with lopes
(Academiei RomaneBucharest, 2012)
Cosmic ray air showers are high energetic particles coming from the Universe toward the
Earth every second. It is well known that they generate electromagnetic waves in the Earth
atmosphere detectable on the ground. LOPES ...
Upper limits on the total cosmic-ray luminosity of individual sources
(Iop Publishing, 2014-07)
In this paper, upper limits on the total luminosity of ultra-high-energy cosmic-rays (UHECR) (E > 10^18 eV) are determined for five individual sources. The upper limit on the integral flux of GeV-TeV gamma-rays is used to ...
An upper limit on the cosmic-ray luminosity of individual sources from gamma-ray observations
(Iop Publishing, 2013-12)
Different types of extragalactic objects are known to produce TeV gamma-rays. Some of these objects are the most probable candidates to accelerate cosmic rays up to 1020 eV. It is very well known that gamma-rays can be ...
KASCADE-Grande measurements of energy spectra for elemental groups of cosmic rays
(Elsevier BVAmsterdam, 2013-07)
The KASCADE-Grande air shower experiment [1] consists of, among others, a large scintillator array for measurements of charged particles, Nch, and of an array of shielded scintillation counters used for muon counting, Nµ. ...
A scenario for the Galactic cosmic rays between the knee and the second-knee
(IOP Publishing, 2019-03-07)
We perform a fit to measurements of the cosmic ray spectrum in the energy range between 10 15 eV and 10 18 eV using data from the TALE, Tunka and Auger experiments. We also fit the data on the depth of shower maximum, X ...
Short-period variation of cosmic-ray intensity and ozone density observed in the stratosphere
(1993-01-01)
The energy deposition by slowing-down of energetic ionizing particles in the atmosphere enhances the production of constituent concentration which perturbs and eventually destroys the ozone (OZ) layer. Near the Brazilian ...
