Context. A population of unidentified gamma-ray sources is forming a structure resembling a halo around the Galactic center. These sources are highly variable, and hence they should be associated with compact objects. Microquasars are objects undergoing accretion with relativistic jets; if such an object has a low-mass, evolved, donor star, it might be found in the Galactic halo. If these low-m...
We have measured the barometer coefficient of cosmic ray neutron production at sea level and find the value —9,25% ± 0,20/cmHg. We have shown that there is no diurnal variation of neutron production of amplitude greater than about 0,4 %. The effects of the large solar flare of November 19th, 1949 on cosmic ray neutrons were much greater than on ionising cosmic rays at sea level; the maximum fac...
The data presented in this article are related to the production of 1:1 Caffeine:Glutaric Acid cocrystals as part of the research article entitled "Green production of cocrystals using a new solvent-free approach by spray congealing" (Duarte et al., 2016) [1]. More specifically, here we present the thermal analysis and the X-ray powder diffraction data for pure Glutaric Acid, used as a raw mate...
Energetic particle production in supernova remnants (SNRs) through diffusive shock acceleration has long been suggested as a mechanism by which the bulk of cosmic rays with energies less than ∼ 10 eV are formed. If highly efficient, this process can have a significant effect on the X-ray emission from SNRs as well as their dynamical evolution. Here we investigate the expected modification to th...
