First results from the microwave air yield beam experiment (MAYBE): Measurement of GHz radiation for ultra-high energy cosmic ray detection [PDF]

open access: diamondEPJ Web of Conferences, 2013
We present measurements of microwave emission from an electron-beam induced air plasma performed at the 3 MeV electron Van de Graaff facility of the Argonne National Laboratory. Results include the emission spectrum between 1 and 15 GHz, the polarization

Treasure Maps for Detections of Extreme Energy Cosmic Rays

open access: yesThe Astrophysical Journal, 2023
The origin of ultra-high-energy cosmic rays is a 60 yr old mystery. We show that with more events at the highest energies (above 150 EeV) it may be possible to limit the character of the sources and learn about the intervening magnetic fields. Individual

Radio detection in the multi-messenger context [PDF]

open access: yesEPJ 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

open access: yesThe 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

open access: yesThe 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.

Feasibility of Correlated Extensive Air Shower Detection with a Distributed Cosmic-Ray Network

open access: yesThe Astrophysical Journal, 2023
We explore the sensitivity offered by a global network of cosmic-ray detectors to a novel, unobserved phenomenon: widely separated simultaneous extended air showers.

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

open access: yesThe 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

A Catalog of the Highest-energy Cosmic Rays Recorded during Phase I of Operation of the Pierre Auger Observatory

open access: yesThe Astrophysical Journal Supplement Series, 2023
A catalog containing details of the highest-energy cosmic rays recorded through the detection of extensive air showers at the Pierre Auger Observatory is presented with the aim of opening the data to detailed examination.

Production of high-energy neutrinos in binary-neutron-star merger events [PDF]

open access: yesEPJ Web of Conferences, 2023
High-energy neutral astrophysical messengers, such as neutrinos and photons, can be produced by the interaction of ultra-high-energy cosmic rays (UHECRs) with radiation fields, either during extragalactic propagation or within source environments ...

Detection of ultra high energy cosmic rays and neutrinos with lunar orbital radio telescope

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Particle cascades induced by ultra-high-energy (UHE) cosmic rays and neutrinos impacting on the lunar regolith usually radiate Cherenkov radio emissions due to the presence of excess negative charge, which is known as Askaryan effect. Several experiments
