The recent release of a Nature paper on twelve Galactic sources, and the detection of photons up to 1.4 PeV revealed the enormous physics potential of LHAASO.
In this contribution, we will briefly illustrate the LHASSO Observatory and its potential and latest published results.
Blazars are potential candidates of cosmic-ray acceleration up to ultrahigh energies (𝐸 > 1 EeV). For an efficient cosmic-ray injection from blazars, 𝑝𝛾 collisions with the extragalactic background light (EBL) and cosmic microwave background (CMB) can produce neutrino spectrum with peaks near PeV and EeV energies, respectively. We analyze the contribution of these neutrinos to the diffuse...
The Telescope Array (TA) is an ultra-high energy cosmic ray detector, the largest in the Northern Hemisphere, sensitive to cosmic rays with energies from 1 PeV to above 100 EeV. The main detector is a hybrid detector consisting of an array of 507 surface detectors covering 700 km$^2$ overlooked by three fluorescence telescope detector stations. The energy range has been extended at the low end...
CTA (Cherenkov Telescope Array) is the next generation ground-based
observatory for gamma-ray astronomy at very-high energies. Once
completed, CTA will outperform present-day facilities by an order of
magnitude in sensitivity, and significantly enlarge the accessible energy
range and survey capabilities. Deployed in the CTA north site, on the
island of La Palma (Spain), LST-1 is the...
Starburst galaxies (SBGs) and more in general starforming galaxies represent a class of galaxies with a high star formation rate (up to 100 Mo/year). Despite their low luminosity, they can be considered as guaranteed “factories” of high energy neutrinos, being “reservoirs” of accelerated cosmic rays and hosting a high density target gas in the central region. The estimation of their point-like...
We report the observation of new properties of primary cosmic-ray neon (Ne), magnesium (Mg), silicon (Si) and iron (Fe) nuclei measured in the rigidity range from 2 GV to 3 TV by the Alpha Magnetic Spectrometer on the International Space Station. The properties of the light primary cosmic-ray helium (He), carbon (C) and oxygen (O) nuclei will be also discussed, showing that Ne, Mg, Si and...
