Giving visibility to BVI (Blind and visually impaired) researchers is fundamental to provide valuable references and encourage young people with a disability to begin a STEM career. In this contribution I describe the objectives, methodologies and activities carried out in the framework of the outreach project "Astroaccesible", aimed at the teaching of astronomy in an inclusive way (i.e....
Neutrinos are most easily detected via their charged current scattering off nucleons. The final state will then contain electromagnetically charged particles, and is subject to QED radiative corrections. Naively power counting suggests that these effects are small, being only relevant for precision observables. In this talk I will explain why this is not the case, and how final state radiation...
Interactions of high-energy protons and nuclei in the Galaxy contribute to the gamma-ray and neutrino signals from the sky in the TeV-PeV energy range. I will review recent results on the search of neutrinos from the Milky Way in this energy range with IceCube and ANTARES telescopes, including recently reported evidence for the overall diffuse emission from the interstellar medium and...
Tau neutrinos are the least known of the active neutrinos. As such, by studying them even far from the precision regime, we stand to gain new insight into their properties and their sources. Doing so endows us with novel probes of fundamental physics and astrophysics that are particularly valuable at high, barely trodden energies. Because tau neutrinos are hard to make and detect, they remain...
The IceCube Neutrino Observatory consists of a cubic kilometer of clear, Antarctic ice instrumented with light-detecting optical modules. These modules detect light produced by charged by-products of neutrino interactions, allowing IceCube to study neutrinos with energies between a few GeV and several PeV. This enables a broad science program, including studies of fundamental neutrino physics;...
The KM3NeT collaboration is building two underwater neutrino detectors in the
Mediterranean: the ARCA (Astroparticle Research with Cosmics in the Abyss) and
ORCA (Oscillation Research with Cosmics in the Abyss) detectors.
ARCA is located off the Sicilian coast of Capo Passero and aims to detect and
identify astrophysical neutrino sources. The ORCA detector, located off the French
coast of...
The detection capabilities of Cherenkov telescopes for observing signals generated by upward-moving extensive air showers (EASs), caused by earth-skimming neutrinos and high-energy cosmic rays, will be examined. We will delve into two detection frameworks: sub-orbital instruments (such as balloon-borne) and low Earth orbit satellites, with a particular emphasis on the Terzina instrument aboard...
With the detection of a diffuse extragalactic neutrino flux and the first compelling evidence for associated sources, IceCube has opened up a new era for high-energy neutrino astronomy. Leveraging on these exciting discoveries made by IceCube, several proposals are under way across the globe to either upgrade existing detectors or build new ones. To definitively unveil the origin of high...
Ultra-High-Energy Neutrinos are expected to be produced both by point-like sources and by the interaction of Ultra-High-Energy Cosmic Rays (UHECRs) with background photons. The Pierre Auger Observatory has the potential to detect such neutrinos with its Surface Detector (SD) array. Its capability to distinguish between cosmic ray and neutrino-induced showers is particularly high for inclined...
Ultra-high-energy (UHE) cosmic neutrinos, with energies above 100 PeV, are
unparalleled probes of the most energetic astrophysical sources and weak interactions at energies beyond the reach of accelerators. GRAND is an envisioned observatory of UHE particles -neutrinos, cosmic rays, and gamma rays - consisting of 200,000 radio antennas deployed in sub-arrays at different locations worldwide....
