Lead, Platinum, and Other Heavy Elements in the Primary Cosmic
From an analysis of ?8~ days of exposure of the Heavy Nuclei Experiment on the HEAO 3 spacecraft, we have selected 322 nuclei with reasonable charge resolution, E ;;::::: 1.3 Ge V n1 and Z ;;::::: 50. These data show a defined ~b~ndance peak in the "platinum" (74 ~ Z ~ 80) region, a small abundance of" lead" (81 ~ Z ~ 83), and a sigmfica~t num~,e~ o~ "_secondary" nuclei in the ~2 ~ Z ~ 73 range...
متن کاملThe Extragalactic Neutrino Background Radiations From Blazars and Cosmic Rays
Blazar emission of gamma rays and cosmic ray production of gamma rays in gas-rich clusters have been proposed recently as alternative sources of the high energy extragalactic diffuse gamma ray background radiation. We show that these sources also produce a very different high energy extragalactic diffuse neutrino background radiation. This neutrino background may be detected by the new generati...
متن کاملHeavy precipitation episodes and cosmic rays variation
In this paper an attempt is made to investigate the possible temporal correlation between heavy precipitation episodes and cosmic rays’ activity, on various time scales. Cosmic rays measurements are sparse and cover less extended periods than those of precipitation. Precipitation is largely influenced by local climatic and even physiographic conditions, while cosmic rays’ distribution is far mo...
متن کاملGeomagnetic Field Eect over Azimuth Anisotropy of Cosmic Rays via Study of Primary Particles
Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...
متن کاملParallel radiations in the primary clades of birds.
Knowledge of avian phylogeny is prerequisite to understanding the circumstances and timing of the diversification of birds and the evolution of morphological, behavioral, and life-history traits. Recent molecular datasets have helped to elucidate the three most basal clades in the tree of living birds, but relationships among neoavian orders (the vast majority of birds) remain frustratingly vex...
