Thunderstorm Charge Distribution Determination Using Cosmic Rays Induced Air Showers and Lightning Imaging at LOFAR

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The LOw Frequency ARray (LOFAR) radio telescope possesses the unique capability to measure ultra‐high energy cosmic rays as well as image lightning discharges. This study presents a comparison between the inferred thunderstorm charge structures derived from cosmic‐ray measurements and from lightning flashes.

Results from the Telescope Array and review of HiRes

open access: yesEPJ Web of Conferences, 2013
A new measurement of the cosmic ray spectrum using the Telescope Array surface arrays is presented. Results on the composition of ultra-high energy cosmic rays from air-fluorescence measurements of shower maximum distributions are presented.

Correlation between the UHECRs measured by the Pierre Auger Observatory and Telescope Array and neutrino candidate events from IceCube

open access: yesEPJ Web of Conferences, 2016
We present the results of three searches for correlations between ultra-high energy cosmic ray events measured by Telescope Array and the Pierre Auger Observatory and high-energy neutrino candidate events from IceCube.

Observation of ultra-high energy cosmic rays with the Telescope Array experiment

open access: yesEPJ Web of Conferences, 2018
The origin of ultra-high energy cosmic rays (UHECRs) has been a longstanding mystery. The Telescope Array (TA) is the largest experiment in the northern hemisphere observing UHECR in Utah, USA. It aims to reveal the origin of UHECR by studying the energy

Ultra high energy cosmic ray neutrinos

open access: yesPhysics Letters B, 1983
Abstract Neutrinos, produced by the collisions of ultra high energy cosmic rays and the 3 K background radiation, require careful treatment of the evolving cosmic ray spectrum. The resulting neutrino differential energy spectrum is flat up to energies of order 10 19 eV, thus most events are expected at this energy.

Has telescope array discovered electroweak monopole?

open access: yesPhysics Letters B
We propose the ultra high energy cosmic ray recently detected by Telescope Array to be the electroweak monopole, and present theoretical arguments which support this.

A Detectable Ultra-high-energy Cosmic-Ray Outburst from GRB 221009A

open access: yesThe Astrophysical Journal
Gamma-ray bursts (GRBs) have been proposed as one of the promising sources of ultra-high-energy cosmic rays (UHECRs), but observational evidence is still lacking.

Neutrinos from Gamma Ray Bursts in the IceCube and ARA Era

open access: yesEPJ Web of Conferences, 2016
In this review I discuss the ultra-high energy neutrinos (UHEN) originated from Cosmic-Rays propogation (GZK neutrinos) and from Gamma Ray Bursts (GRBs), and discuss their detectability in kilometers scale detectors like ARA and IceCube.
