The Air Microwave Yield (AMY) experiment to measure the GHz emission from air shower plasmas

EPJ Web of Conferences, 2013
The AMY experiment aims to measure the Microwave Bremsstrahlung Radiation (MBR) emitted by air-showers secondary electrons accelerating in collisions with neutral molecules of the atmosphere. The measurements are performed at the Beam Test Facility (BTF)

Ultra-high-energy cosmic ray and neutrino physics using the Moon

, 2010
The intriguing mystery of ultra-high energy (UHE) cosmic particles is the nature of their sources. In this presentation we indicate how these UHE particles, in order to uncover their sources, can be detected using radio observations of the Moon.

The attenuation of atmospheric Cerenkov photons [PDF]

, 2002
Whilst the atmosphere places a limit on the successful applications of many branches of astronomy, it becomes an invaluable tool for the detection of very high energy γ-rays. This thesis is concerned with reducing the systematic uncertainties inherent to

Perspective of monochromatic gamma-ray line detection with the High Energy cosmic-Radiation Detection (HERD) facility onboard China's space station

, 2016
HERD is the High Energy cosmic-Radiation Detection instrument proposed to operate onboard China's space station in the 2020s. It is designed to detect energetic cosmic ray nuclei, leptons and photons with a high energy resolution (similar to 1% for ...

Ultrahigh-energy Cosmic Rays from Neutrino-emitting Tidal Disruption Events

The Astrophysical Journal
We revisit ultrahigh-energy cosmic-ray (UHECR) production in tidal disruption events (TDEs) in light of recent evidence of neutrino-TDE associations.

On the Potential Cosmogenic Origin of the Ultra-high-energy Event KM3-230213A

The Astrophysical Journal Letters
On 2023 February 13, the KM3NeT/ARCA telescope observed a track-like event compatible with a ultra-high-energy muon with an estimated energy of 120 PeV, produced by a neutrino with an even higher energy, making it the most energetic neutrino event ever ...

The Observational Signatures of Cosmic Strings

, 2009
Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification models and in theories with extended additional dimensions.
