Radio detection in the multi-messenger context [PDF]

EPJ Web of Conferences, 2019
The present work discusses the development of the radio technique for detection of ultra-high energy air-showers induced by cosmic radiation, and the prospects of its application in the future multi-messenger activities, particularly for detection of ...

Constraints on the Hosts of UHECR Accelerators

The Astrophysical Journal Letters, 2023
Interactions of ultra-high-energy cosmic rays (UHECRs) in the surroundings of their accelerators can naturally explain the observed spectrum and composition of UHECRs, including the abundance of protons below the ankle.

Acceleration and Spectral Redistribution of Cosmic Rays in Radio-jet Shear Flows

The Astrophysical Journal, 2023
A steady-state, semi-analytical model of energetic particle acceleration in radio-jet shear flows due to cosmic-ray viscosity obtained by Webb et al. is generalized to take into account more general cosmic-ray boundary spectra.

A new limit on the Ultra-High-Energy Cosmic-Ray flux with the Westerbork Synthesis Radio Telescope [PDF]

, 2010
A particle cascade (shower) in a dielectric, for example as initiated by an ultra-high energy cosmic ray, will have an excess of electrons which will emit coherent \v{C}erenkov radiation, known as the Askaryan effect.

Effects of the Galactic Magnetic Field on the UHECR Correlation Studies with Starburst Galaxies

The Astrophysical Journal, 2023
We estimate the biases caused by the coherent deflection of cosmic rays due to the Galactic magnetic field (GMF) in maximum likelihood analyses for searches of ultrahigh-energy cosmic-ray sources in the literature. We simulate mock event data sets with a

Cosmic rays in early star-forming galaxies and their effects on the interstellar medium [PDF]

, 2017
Galaxies at high redshifts with strong star formation are sources of high-energy cosmic rays. These cosmic rays interact with the baryon and radiation fields of the galactic environment via photo-pair, photo-pion and proton-proton processes to produce ...

ABOUT EXPANSION OF TERRESTRIAL RADIOPHYSICAL METHODS FOR DETECTION OF ULTRA-HIGH-ENERGY COSMIC RAY

Odessa Astronomical Publications, 2013
Low arrival density of the ultra-high- energy cosmic rays is one of the main obstacles of their experimental research. Overcoming this problem was based on the increase in the sensitive area of terrestrial facilities.
