Upper limits on the total cosmic-ray luminosity of individual sources
(Institute of Physics - IOPBristol, 2014-07)
In this paper, upper limits on the total luminosity of ultra-high-energy cosmic-rays (UHECR) E > '10 IND. 18'eV) are determined for five individual sources. The upper limit on the integral flux of GeV-TeV gamma-rays is ...
The shape of the extragalactic cosmic ray spectrum from galaxy clusters
(IOP Publishing, 2016-08-05)
We study the diffusive escape of cosmic rays from a central source inside a galaxy cluster to obtain the suppression in the outgoing flux appearing when the confinement times get comparable or larger than the age of the ...
Analysis of atmospheric pressure and temperature effects on cosmic ray measurements
(American Geophysical Union, 2013-04-30)
In this paper, we analyze atmospheric pressure and temperature effects on the records of the cosmic ray detector CARPET. This detector has monitored secondary cosmic ray intensity since 2006 at Complejo Astronómico El ...
An upper limit on the cosmic-ray luminosity of individual sources from gamma-ray observations
(Institute of Physics - IOPBristol, 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 '10 POT.20' eV. It is very well known that gamma-rays can ...
Large-scale cosmic ray fluctuations inferred from the ground-based neutron and ionizing component observations and their relevance to cosmic ray anisotropyLarge-scale cosmic ray fluctuations inferred from the ground-based neutron and ionizing component observations and their relevance to cosmic ray anisotropy

On the relation between the astrophysical neutrino fluxes and the cosmic ray fluxes
(IOP Publishing, 2021-08)
Some generalizations of the relation between high-energy astrophysical neutrino and cosmic ray fluxes are obtained, taking into account present results on the cosmic ray spectrum and composition as well as a more realistic ...
A faraway quasar in the direction of the highest energy Auger event
(IOP PUBLISHING LTD, 2010)
The highest energy cosmic ray event reported by the Auger Observatory has an energy of 148 EeV. It does not correlate with any nearby (z<0.024) object capable of originating such a high energy event. Intrigued by the fact ...
