Detecting Ultra High Energy Cosmic Rays (UHECRs) enables us to measure the proton-air
inelastic cross section σ inel p–air at energies that we are unable to access with particle …

The source of UHECRs still remains a mystery over a century after the first cosmic rays were
observed by Hess in 1912. The flux of cosmic rays above the knee,⪆ 1015 eV, displays …

Among the analysis strategies used in IceCube, searches for neutrinoinduced particle
showers, so called cascades, provide good energy resolution and a relative low …

The problem of cosmic ray mass composition is considered in the context of its current state
and prospects for achieving progress in the nearest future due to improving data quality of …

由于大型宇宙线探测器Pierre Auger, Telescope Array 等的观测, 极高能宇宙线(能量大于10^
18eV 的宇宙线) 的研究取得了很大进展, 包括探测到高能能谱变陡, 与河外天体源的可能相关性 …

Since the discovery of cosmic rays in the early 20th century, physicists have strived to gain a
deeper understanding of the properties behind the universe's most energetic particles …

The" Lomonosov" satellite, with the TUS instrument on board, was launched on April 28,
2016 on solar-synchronized orbit with altitude about 500 km. The main goal of TUS space …

Ultra high energy cosmic rays (UHECRs) are particles, likely protons and/or nuclei, with
energies up to eV that are observed through the giant air showers they produce in the …

Ultra-high energy cosmic ray (UHECR) sources are still unknown, though the lack of any
strong anisotropy largely rules out galactic origin for energies above 1019. 0 eV. The …

This work is about Tunka-Rex, a radio detector for air showers in Siberia. After calibrating
the detector and developing a reconstruction method for air shower events, three results are …
