Measurement of Cosmic-ray Energy Spectrum with the TALE Detector in Hybrid Mode [PDF]

open access: yesEPJ Web of Conferences, 2023
The TA Low-energy Extension (TALE) experiment extends the energy range observed by the TA experiment to below 1016 eV. We aim to study the transition from galactic to extragalactic cosmic rays.

The Updated Version of the A.Ne.Mo.S. GLE Alert System: The Case of the Ground-Level Enhancement GLE73 on 28 October 2021

open access: yesUniverse, 2022
A ground-level enhancement (GLE) event is a sudden increase in cosmic ray intensity originated by solar sources and recorded by ground-based detectors. GLEs are invariably associated with large solar flares that can release and accelerate solar particles

TAx4 surface detectors data analysis [PDF]

open access: yesEPJ Web of Conferences, 2023
The TAx4 experiment aims to understand UHECR by expanding the observation area of the TA experiment by a factor of 4 and increasing the statistics of UHECR events with energy greater than 1019 eV.

Leading cluster approach to simulations of hadron collisions with GHOST generator [PDF]

open access: yesEPJ Web of Conferences, 2019
The model HDPM of CORSIKA has been updated and developed on the base of the recent measurements by ALICE, CMS, TOTEM, LHCb, LHCf... The new model, GHOST, involving a four-source production reproduces correctly the pseudo-rapidity distributions of charged

Estimation and reduction of the biases by the galactic magnetic field on the UHECR correlation studies [PDF]

open access: yesEPJ Web of Conferences, 2023
The correlation studies between ultrahigh-energy cosmic ray (UHECR) anisotropy and source candidates are keys to understand the origin of UHECRs.

Ground strains induced by the 2022 Hunga-Tonga volcanic eruption, observed by a 1500-m laser strainmeter at Kamioka, Japan

open access: yesEarth, Planets and Space, 2023
In this study, we detected the horizontal ground strains induced by the atmospheric Lamb wave emitted from the 2022 eruption of the Tonga–Hunga Ha’apai undersea volcano, at an underground observatory in Kamioka, Japan.

The origin of cosmic rays [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1999
It is generally regarded that the bulk of cosmic rays originate in the Galaxy and that those below the 'knee' (the rapid steepening in the energy spectrum) at a few PeV come from Galactic supernovae, the particles being accelerated by the shocks in the supernova remnants.

An interacting molecular cloud scenario for production of gamma-rays and neutrinos from MAGIC J1835-069, and MAGIC J1837-073

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Recently the MAGIC telescope observed three TeV gamma-ray extended sources in the galactic plane in the neighborhood of radio SNR G24.7+0.6. Among them, the PWN HESS J1837-069 was detected earlier by the HESS observatory during its first galactic plane ...

Is non-particle dark matter equation of state parameter evolving with time?

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Recently, the so-called Hubble Tension, i.e. the mismatch between the local and the cosmological measurements of the Hubble parameter, has been resolved when non-particle dark matter is considered which has a negative equation of state parameter ...
