High Energy Cosmic Rays - 1
- Valerio Verzi (Istituto Nazionale di Fisica Nucleare)
In this talk, I will discuss how local insteller environment may affect the oberved properties of cosmic rays in general and small scale anisotropy in particular. It is shown that a generalization of the Compton Getting effect can give rise to small scale anisotropy with a turbulent spectrum of scattering centers.
The High-Energy Particle Detector (HEPD-01) onboard the China Seismo-Electromagnetic Satellite (CSES-01) - launched in February 2018 - is a light and compact payload suitable for measuring electrons (3-100 MeV), protons (30-300 MeV), and light nuclei (up to a few hundreds MeV/n). The very good capabilities in particle detection and separation, the high energy resolution, a wide angular...
Measuring the energy spectrum of cosmic electrons+positrons in the energy range 50 GeV - few TeV can provide evidence of the existence of local sources of either an astrophysical or exotic nature (such as dark matter). Several results have been reported in the last years and there are significant differences among some of them, particularly at higher energies where uncertainties are more...
I will present a new model of the coherent Galactic magnetic field outside of the thin disk. The model was fitted to the most recent catalog of extragalactic Faraday rotation measures (RM) and synchrotron polarization data (Stokes Q and U). The model is based on several phenomenological components of the GMF -- the spiral arms, the toroidal halo, the X-shaped field and the compressed field of...
The current generation of Charged Cosmic Ray (CCR) experiments in operation in space (e.g. AMS-02, DAMPE, CALET) is providing novel information and is measuring unexpected features that are challenging the phenomenological community to revisit the paradigms behind the established theories of cosmic-ray origin, acceleration and propagation, and to formulate comprehensive models able to...
The Large High-Altitude Air Shower Observatory (LHAASO) is a hybrid detector experiment that includes a one-square-kilometer array of scintillator detectors and muon detectors, a 78,000-square-meter water Cherenkov detector array, and 18 wide-field-of-view Cherenkov telescopes. The multi-parameter observation of showers allows LHAASO to measure the single-element energy spectrum with high...
To uncover the sources of ultra-high-energy cosmic rays, three main observables are measured at the Pierre Auger Observatory - the cosmic-ray energies, the depths of maximum air shower development, and the arrival directions. At energy E>8 EeV, the arrival directions exhibit a dipolar structure pointing away from the center of our Galaxy indicating an extragalactic origin of cosmic rays at...
