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...
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 investigate homogeneous and isotropic cosmological solutions supported by the SU(2) gauge field governed Born-Infeld lagrangian. In framework of Friedmann-Robertson-Walker cosmology, with or without constant $\lambda$, we derive dynamical systems that give rather complete description space solutions. For $\lambda=0$ effective equation state $\ve(p)$ is shown to interpolate between $p=-\ve/3$ in regime strong $p=\ve/3$ for weak field. Correspondingly, Universe starts zero acceleration...

Context . Observations of meteors in the Earth’s atmosphere offer a unique tool for determining flux meteoroids that are too small to be detected by direct telescopic observations. Although these objects routinely observed from ground-based facilities, such as meteor and fireball networks, space-based instruments come with notable advantages have potential achieve broad uniform exposure. Aims In this paper, we describe first observations events Mini-EUSO, very wide field-of-view telescope...
Fluorescence telescopes are among the key instruments used for studying ultra-high energy cosmic rays in all modern experiments. We use model data a small ground-based telescope EUSO-TA to try some methods of machine learning and neural networks recognizing tracks extensive air showers its reconstruction arrival directions primary particles. also comment on opportunities this approach other fluorescence outline possible ways improving performance suggested methods.
The interior structure of the static spherically symmetric black holes in SU(2) Einstein-Yang-Mills theory is investigated both analytically and numerically. It shown that violation no-hair conjecture this has a nontrivial manifestation also inside event horizon. Although Schwarzschild Reissner-Nordstr\"om-type interiors still may be realized for certain discrete horizon radii, generic solution exhibits an infinitely oscillating behavior near singularity. No inner horizons are formed...
