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

Universe, 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

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

TAx4 surface detectors data analysis [PDF]
EPJ 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.

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

European 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 ...

Investigating an angular correlation between nearby starburst galaxies and UHECRs with the Telescope Array experiment [PDF]
EPJ Web of Conferences, 2019 The arrival directions of cosmic rays detected by the Pierre Auger Observatory (Auger) with energies above 39 EeV were recently reported to correlate with the positions of 23 nearby starburst galaxies (SBGs): in their best-fit model, 9.7% of the cosmic ...
