A Study on anisotropy of cosmic ray distribution with a small array of water-cherenkov detectors [PDF]
, 2007 The study of the anisotropy of the arrival directions is an essential tool to investigate the origin and propagation of cosmic rays primaries. A simple way of recording many cosmic rays is to record coincidences between a number of detectors.

Receiving vectors of muon telescope of cosmic ray station Novosibirsk
Solar-Terrestrial Physics, 2016 The method of receiving vectors allows us to determine cosmic ray anisotropy at every moment of time. Also, the method makes it possible to study fast anisotropy fluctuations related to the interplanetary medium dynamics.

Air Shower Detection by Arrays of Radio Antennas [PDF]
EPJ Web of Conferences, 2019 Antenna arrays are beginning to make important contributions to high energy astroparticle physics supported by recent progress in the radio technique for air showers. This article provides an update to my more extensive review published in Prog.

On the disintegration of cosmic ray nuclei by solar photons [PDF]
, 1999 We discuss in detail the possibility of observing pairs of simultaneous parallel air showers produced by the fragments of cosmic ray nuclei which disintegrated in collisions with solar photons. We consider scenarios with different cosmic ray compositions,

Molecular Clouds as Cosmic-Ray Barometers [PDF]
, 2010 The advent of high sensitivity, high resolution gamma-ray detectors, together with a knowledge of the distribution of the atomic hydrogen and especially of the molecular hydrogen in the Galaxy on sub-degree scales creates a unique opportunity to explore ...

Boosted dark matter quarrying at surface neutrino detectors
Journal of High Energy Physics, 2018 We propose the idea of “Earth Shielding” to reject cosmic-ray backgrounds, in the search for boosted dark matter at surface neutrino detectors, resulting in the enhancement of the signal-to-background ratio.

High energy cosmic-rays: puzzles, models, and giga-ton neutrino telescopes
, 2003 The existence of cosmic rays of energies exceeding 10^20 eV is one of the mysteries of high energy astrophysics. The spectrum and the high energy to which it extends rule out almost all suggested source models.

The HiSPARC-UK Cosmic Ray Detector [PDF]
Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2018 The international HiSPARC project is a collaboration between schools and academic institutions across Europe in real scientific research, and won the European Physical Society HEP outreach prize in 2007. It was born more than a decade ago in the Netherlands, with ongoing participation of over 100 schools.

Determining the fraction of cosmic-ray protons at ultrahigh energies with cosmogenic neutrinos [PDF]
Physical Review D, 2019 Cosmogenic neutrinos are produced when ultra-high-energy cosmic rays (UHECRs) interact with cosmological photon fields. Limits on the diffuse flux of these neutrinos can be used to constrain the fraction of protons arriving at Earth with energies $E_{p} \
