Highest energy neutrino in ICECUBE (hundred TeV or PeVs) suggested since five years the birth of a Neutrino Astronomy. However the possible pollution by atmospheric neutrino signals, in particular prompt charmed ones, might offuscate the ability to discover the main astrophysical UHE neutrino sources. Indeed up to now no AGN or GRB or galactic sharp signal have detected. A possible guaranteed, ... More

The equation of state (EoS) of nuclear matter is one of the key issues in understanding the internal structure of neutron stars (NS), the remnants of massive stellar collapses. They populate the plane of our Galaxy, isolated or in binary systems, and play a crucial role in the indirect (Hulse & Taylor 1975) and direct (Abbott et al. 2017a) testing of the existence of gravitational waves (GWs). Th ... More

Ultra-high energy cosmic rays are observed through the giant air showers they produce in the atmosphere. With the construction and operation of the new generation of cosmic-ray experiments—the Pierre Auger Observatory in the Southern hemisphere and the Telescope Array in the Northern one—the study of these particles, the most energetic ever detected, has experienced a jump in statistics as we ...

The electromagnetic counterpart of the binary neutron star merger GW170817 has been monitored from early to very late times at all wavelengths. In this talk, we discuss the temporal evolution of the associated afterglow emission in the X-rays and radio bands. These observations seem finally to support a flattening/decaying behaviour, favouring the "structured jet" interpretation for the origin of ... More

I will review the AMS-02 data and the measurements performed in the first 7-years of data taking. I will then discuss the perspectives of the AMS-02 cosmic ray data in the landscape of the current puzzling scenario of the astroparticle physics.

Despite much effort in the past, only very recently the first true multi-messenger measurements have been made. Gamma ray emission has been seen from a gravitational wave merger event and a gamma transient has been seen in coincidence with a high-energy neutrino event. Thus, the excitement and expectations are high, even though the journal papers are just written. Both events are transients of ra ... More

It has been known since the ‘50s that the lattice structure may strongly influence the electromagnetic processes in oriented crystals. In particular, if a beam of electrons or photons is aligned with the crystalline axes or planes, the probability of bremsstrahlung or pair production, respectively, are strongly enhanced. This results in a shortening of the radiation length, X0, and thereby of th ... More

We present the results of the observations of the Sun in its quiescent state with Fermi-LAT in almost 10 years on orbit. The high energy gamma-ray emission from the Sun is due to the interactions of cosmic ray (CR) protons and electrons with matter and photons in the solar environment. Such interactions lead to two component gamma-ray emission: a disk-like emission due to the nuclear interactions ... More
