On Anisotropy of Ultra-High Energy Cosmic-Rays

TL;DR

This paper investigates the anisotropy of ultra-high energy cosmic rays by introducing a correlation statistic with large-scale structure and discusses comparisons with recent statistical methods.

Contribution

It presents a new statistical measure for analyzing the correlation between UHECRs and large-scale structure, and compares it with existing methods.

Findings

Proposed a correlation statistic for UHECR anisotropy analysis

Compared new statistic with improved KS statistics

Summarized implications for cosmic-ray anisotropy studies

Abstract

We briefly summarize our study on anisotropy of Ultra-High Energy Cosmic-Rays (UHECRs), in which we define a statistics that measures the correlation between UHECRs and Large Scale Structure (LSS). We also comment here on recently published paper by Koers and Tinyakov that compared our statistics to improved KS statistics.
