Examination of Xmax anisotropy for the next generation Ultra-high energy cosmic rays observations [PDF]

open access: yesEPJ Web of Conferences, 2023
The estimation of mass composition ultra-high energy cosmic rays is essential to understand their origin and generation mechanism. Recent experiments are expected to discover anisotropy of mass composition in ultra-high energy cosmic rays.

Ultra High Energy Cosmic Ray Source Models: Successes, Challenges and General Predictions [PDF]

open access: yesEPJ Web of Conferences, 2023
Understanding the acceleration of Ultra High Energy Cosmic Rays is one of the great challenges of contemporary astrophysics. In this short review, we summarize the general observational constraints on their composition, spectrum and isotropy which ...

Search for the large-scale cosmic-ray anisotropies using the TA and TALE surface detector arrays [PDF]

open access: yesEPJ Web of Conferences, 2023
Origins of ultra-high-energy cosmic rays (UHECRs) are still largely unknown. In particular, the “2nd knee” around 1017 eV could be related to a transition of origins from the galactic to extra-galactic sources.

Towards extracting cosmic magnetic field structures from cosmic-ray arrival directions

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We present a novel method to search for structures of coherently aligned patterns in ultra-high energy cosmic-ray arrival directions simultaneously across the entire sky.

ATLAS and ultra high energy cosmic ray physics

open access: yesEPJ Web of Conferences, 2017
After a brief introduction to extended air shower cosmic ray physics the current and future deployment of forward detectors at ATLAS is discussed along with the various aspects of the current and future ATLAS programs to explore hadronic physics.

Search for ultra high energy cosmic ray sources

open access: yesEPJ Web of Conferences, 2017
Earlier we suggested a new method to search for sources and anisotropy of the arrival directions of ultra high energy particles. Here using this method we analyzed the data of the Yakutsk EAS array and found that particle fluxes with energies E < 4.1019 ...

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.

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

Cosmic-Ray Database Update: Ultra-High Energy, Ultra-Heavy, and Antinuclei Cosmic-Ray Data (CRDB v4.0)

open access: yesUniverse, 2020
We present an update on CRDB, the cosmic-ray database for charged species. CRDB is based on MySQL, queried and sorted by jquery and table-sorter libraries, and displayed via PHP web pages through the AJAX protocol. We review the modifications made on the
