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 ...
Periodicidades no fluxo de raios cósmicos e análise de choques interplanetários
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2010-01-08)
Muons and neutrons that reach the Earth surface with high energy constitute a particles’ group called secondary cosmic rays. In order to study the flux of this particles data from muons and neutrons stations are used. The ...
Radioresistance of adenine to cosmic rays
(2017)
The presence of nucleobases in carbonaceous meteorites on Earth is an indication of the existence of this class of molecules in outer space. However, space is permeated by ionizing radiation, which can have damaging effects ...
Evidence for cosmic ray modulation in temperature records from the South Atlantic Magnetic Anomaly region
(Copernicus PublicationsBerlin, 2013)
Possible direct or indirect climatic effects related to solar variability and El Niño–Southern Oscillation (ENSO) were investigated in the southern Brazil region by means of the annual mean temperatures from four weather ...
Um novo modelo climático simplificado: global resolved energy balance with galactic cosmic rays (GREB-GCR) theory
(Revista Brasileira de Geografia Física, 2020)
This work was based on the development of a climate model capable of simulating the effects of the Galactic Cosmic Rays theory (GCR) on the global climate system. This new model is being called the Global Resolved Energy ...
Radiolysis of cytosine at cryogenic temperatures by swift heavy ion bombardments
(2022)
We investigated the radiolysis effects on the cytosine in the solid phase irradiated by swift heavy ions as galactic cosmic ray analogues (GCRs). Infrared (IR) absorption spectroscopy was employed to monitor the physical ...
Superposed epoch study of ICME sub-structures near Earth and their effects on Galactic cosmic rays
(EDP Sciences, 2016-05)
Context. Interplanetary coronal mass ejections (ICMEs) are the interplanetary manifestations of solar eruptions. The overtaken solar wind forms a sheath of compressed plasma at the front of ICMEs. Magnetic clouds (MCs) are ...
Supernova Remnants interactiong with molecular clouds: X-ray and Gamma-ray signatures
(Springer, 2014-07)
The giant molecular clouds (MCs) found in the Milky Way and similar galaxies play a crucial role in the evolution of these systems. The supernova explosions that mark the death of massive stars in these regions often lead ...
On the influence of non-thermal pressure on the mass determination of galaxy clusters
(EDP SCIENCES S A, 2010)
Aims. Given that in most cases just thermal pressure is taken into account in the hydrostatic equilibrium equation to estimate galaxy cluster mass, the main purpose of this paper is to consider the contribution of all three ...
