JEM
EUSO Experiment: Scientific Objectives
Main Objectives:
- Astronomy and
astrophysics through particle channel with extreme energies > 1020
eV
- Identification
of sources by the high-statistics arrival direction analysis
- Measurement
of the energy spectra from individual sources to constrain acceleration or
emission mechanisms
Exploratory Objectives:
- Detection
of extreme energy gamma-rays
- Detection
of extreme energy neutrinos
- Study
of the Galactic magnetic field
- Verification
of the relativity and the quantum gravity effect in extreme energy
- Global
of nightglows, plasma discharges and lightning
Cosmic Ray UHE spectrum: esperimental results on the existence of the GKZ cut-off. In red data by Auger (2008).
GZK cut-off recently confirmed by Telescope Array
Can we find the origin of these UHE or EHE Cosmic Rays? A 10^20 eV proton is almost not deflected in the galactic and intergalactic magnetic field
(uG) so in principle we can try to trace it back to the source ...
Another important result by Auger in 2007: Observation of anisotropy in EHE (E>10^19 eV) CR arrival direction.
Can we start to imagine a particle astronomy?
