Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to accurately observe ultra-high-energy cosmic rays (UHECRs) and neutrinos from space with sensitivity over the full celestial sky. POEMMA will air fluorescence produced by extensive showers (EASs) UHECRs potentially UHE above 20 EeV. Additionally, has ability Cherenkov signal upward-moving EASs induced Earth-interacting tau PeV. spacecraft are quickly re-orientate follow up transient neutrino sources obtain...
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) mission is being designed to establish charged particle astronomy with ultra-high energy cosmic rays (UHECRs) and observe cosmogenic tau neutrinos (CTNs). study of UHECRs CTNs from space will yield orders-of-magnitude increase in statistics observed at the highest energies observation flux for a range UHECR models. These observations should solve long-standing puzzle origin particles ever observed, providing new window onto most...
K-EUSO (KLYPVE-EUSO) is a planned orbital mission aimed at studying ultra-high energy cosmic rays (UHECRs) by detecting fluorescence and Cherenkov light emitted extensive air showers in the nocturnal atmosphere of Earth ultraviolet (UV) range. The observatory being developed within JEM-EUSO collaboration to be deployed on International Space Station after 2025 operated for least two years. telescope, consisting ∼105 independent pixels, will allow spatial resolution ∼0.6 km ground, and, from...
We examine the behavior of spherical silica particles trapped at an air–nematic liquid crystal interface. When a strong normal anchoring is imposed, beads spontaneously form various structures depending on their area density and nematic thickness. Using optical tweezers, we determine pair potential explain formation these patterns. The energy profile discussed in terms capillary elastic interactions. Finally, detail mechanisms that control hexagonal lattice analyze role gravity for curved interfaces.
Fission times of uraniumlike nuclei with excitation energies up to about 250 MeV have been inferred from blocking effects in a single crystal. They are found longer by at least 1 order magnitude than the ones obtained other techniques, hint for very broad fission time distributions.
EUSO-SPB2 is a second generation Extreme Universe Space Observatory (EUSO) on Super-Pressure Balloon (SPB). This document describes the physics capabilities, proposed technical design of instruments, and simulation analysis software.
Abstract Mini-EUSO is part of the JEM-EUSO program and operates on board International Space Station (ISS). It a UV-telescope with single-photon counting capability looking at nighttime downwards to Earth through nadir-facing UV-transparent window. As pre-flight tests, engineering model, telescope 1/9 original focal surface lens 2.5 cm diameter, has been built tested. Tests model have made in laboratory open-sky conditions. Laboratory tests performed TurLab facility, located Physics...
Abstract The EUSO@TurLab project aims at performing experiments to reproduce Earth UV emissions as seen from a low orbit by the planned missions of JEM-EUSO program. It makes use TurLab facility, which is laboratory, equipped with 5 m diameter and 1 depth rotating tank, located Physics Department University Turin.
