Weak Turbulence Cascading Effects in the Acceleration and Heating of Ions in the Solar Wind
(2014-02-01)
We study the wave¨Cparticle interaction and the evolution of electromagnetic waves propagating through a solarwind-
like plasma composed of cold electrons, isotropic protons, and a small portion of drifting anisotropic ...
CENTAURUS A: THE EXTRAGALACTIC SOURCE OF COSMIC RAYS WITH ENERGIES ABOVE THE KNEE
(IOP PUBLISHING LTDBRISTOL, 2012)
The origin of cosmic rays at all energies is still uncertain. In this paper, we present and explore an astrophysical scenario to produce cosmic rays with energy ranging from below 10(15) to 3 x 10(20) eV. We show here that ...
Latest results from the KASCADE-Grande experiment
(Elsevier BVAmsterdam, 2014-04)
The KASCADE-Grande experiment operated at KIT from January 2004 to November 2012, measuring EAS generated by primary cosmic rays in the 1016–1018 eV energy range. The experiment detected, for each single event, with a high ...
Active galactic nuclei: sources for ultra high energy cosmic rays
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst, in the radio galaxy Cen A which is pushed up in energy by the shock of a relativistic jet. ...
Luminescent properties of hybrid materials prepared by the polymeric precursor method
(2013-07-22)
Rare earth complexes (RE) can be incorporated in silica matrixes, originating organic/inorganic hybrid materials with good thermal stability and high rare earth emission lines. In this work, the hybrid material was obtained ...

Quantum dynamics of scalar particles in the space–time of a cosmic string in the context of gravity's rainbow
(2020-10-01)
We analyze the dynamics of scalar particles in gravity's rainbow considering the space–time of a cosmic string in this modified gravity. Thus, we solve the Klein–Gordon equation for two types of potential in which two ...
Observation of a muon excess following a gamma-ray burst event detected at the International Space Station

Low energy X-ray grating interferometry at the Brazilian Synchrotron
(2017-06-15)
Grating based X-ray differential phase contrast imaging has found a large variety of applications in the last decade. Different types of samples call for different imaging energies, and efforts have been made to establish ...
