Slides presented during the lecture
Description
The Auger experiment (PAO), a ground-based hybrid experiment: goals.
The detection techniques of Auger: the surface detector (SD) and the fluorescence detector (FD).
Reconstruction of the energy and of the direction of the primary cosmic ray with the SD.
Reconstruction of the energy and of the mass of the primary cosmic ray with the FD.
The cosmic ray flux above 2.5 EeV measured by Auger.
The hypotheses about the energy spectrum suppression above 50 EeV: a source or a propagation effect?
Future perspectives for the Auger experiment: Auger Prime.
Neutral cosmic rays: photons.
The GeV and the TeV astronomy.
Production mechanisms of photons.
The multi-wavelength flux density of the Crab Nebula.
The three different kinds of gamma-ray experiments.
The Fermi satellite: the science program and the two on-board instruments (LAT and GBM).
The gamma-ray full-sky map reconstructed with Fermi and DAMPE.
The Fermi source catalog, the detection of GRB 090510, the gamma-ray counterpart of the gravitational wave detected on August 17, 2017 (an example of multimessenger astronomy).
