The detection by the KM3NeT experiment of a neutrino with a record-breaking energy of 220 PeV represents a major milestone in neutrino astrophysics. I will review the broader implications of this observation in a full-sky context, including its combination with data from other experiments, searches for the potential source of this event and population studies of similar astrophysical objects,...

In this report, we would like to present some interesting recent results and developments in ground-based gamma-ray and cosmic-ray astrophysics, using the MAGIC IACT and some other well-known detectors as examples. Measuring Cherenkov light from air showers has become a standard, highly sensitive method for investigating sources in the energy range from a few tens of GeV to 100 TeV. The...

Very-high-energy (VHE) gamma rays provide a unique window on the most extreme astrophysical environments and are a key probe of potential multi‑messenger sources. To fully exploit this potential, the Cherenkov Telescope Array Observatory (CTAO) is being built as the next‑generation facility for VHE gamma‑ray astronomy, offering an order‑of‑magnitude improvement in sensitivity, a wide energy...

40. UHECR anisotropy and search for their sources

Mikhail Kuznetsov (INR RAS)

Ultra-high energy cosmic rays (UHECR) are charged particles, with energies greater than 1 EeV that are reaching the Earth from space. The origin of UHECR and their nature remain unknown. In this talk I will discuss the studies of distribution of UHECR arrival directions over the sky in search for their sources, that are expected to be extragalactic. I will also discuss the method of estimation...
