Cosmic Rays and how they are observed on the Sky

by Dr. Eduardo de la Fuente Acosta
(Instituto de Astronomia y Meteorologia,
Universidad de Guadalajara)


At the beginning of the 21st century, experiments in both the Northern and Southern hemispheres have observed a small but measurable energy- dependent sidereal anisotropy in the arrival direction distribution of galactic cosmic rays with a relative amplitude of $10^{-4} - 10^{-3}$. However, each one of these individual measurements is restricted by limited sky coverage.

The best way to address this issue, in order to understand the origin of this anisotropy, is doing a joint analysis on all angular scales using cosmic-ray data with ad-hoc instruments on both hemispheres overlapping field of view.

In this talk, I present an overview about this observed cosmic-ray anisotropy, including both a description of methods and actual efforts that can generate value information to understand this topic that provides important information on the propagation mechanisms of cosmic rays and on the identification of sources.

Coffee and tea will be served 20 minutes prior to the seminar.
Anyone interested is welcome to attend.
