Techniques to study cosmic ray anisotropies
These lectures review some of the techniques used to analyse the arrival direction distribution of Cosmic Rays, and some relevant results on the field.
متن کاملNumerical Likelihood Analysis of Cosmic Ray Anisotropies
A numerical likelihood approach to the determination of cosmic ray anisotropies is presented which offers many advantages over other approaches. It allows a wide range of statistically meaningful hypotheses to be compared even when full sky coverage is unavailable, can be readily extended in order to include measurement errors, and makes maximum unbiased use of all available information.
متن کاملPhysics with Cosmic Neutrinos, Pev to Zev
Neutrinos offer a particularly promising eye on the extreme Universe. Neutrinos are not attenuated by intervening radiation fields such as the Cosmic Microwave Background, and so they are messengers from the very distant and very young phase of the universe. Also, neutrinos are not deflected by cosmic magnetic fields, and so they should point to their sources. In addition, there are particle ph...
متن کاملHidden Cosmic-Ray Accelerators as an Origin of TeV-PeV Cosmic Neutrinos.
The latest IceCube data suggest that the all-flavor cosmic neutrino flux may be as large as 10^{-7} GeV cm^{-2} s^{-1} sr^{-1} around 30 TeV. We show that, if sources of the TeV-PeV neutrinos are transparent to γ rays with respect to two-photon annihilation, strong tensions with the isotropic diffuse γ-ray background measured by Fermi are unavoidable, independently of the production mechanism....
متن کاملSearches for cosmic ray anisotropies at ultra - high energies
We report the different analyses of the arrival directions of ultra-high energy cosmic rays detected at the Pierre Auger Observatory. In the range of energy considered there, two kinds of anisotropies are expected to be observed : point sources at the highest energies and large-scale pattern at lower energies. We report the update of the correlation with Active Galactic Nuclei. Then, from the a...
