About UHECR Today

An independent resource dedicated to ultra-high-energy cosmic ray science and the search for their origins.

The Mission

UHECR Today exists to make ultra-high-energy cosmic ray science accessible to everyone — from curious students to professional physicists. We believe that open data and transparent methodology are essential for scientific progress.

The site serves as a central hub for UHECR research, providing educational content, links to public data sources, and reporting on new discoveries — including original research conducted using publicly available datasets.

The Discovery

In 2025, analysis of public data from the Pierre Auger Observatory and LIGO/Virgo/KAGRA revealed an unexpected correlation: ultra-high-energy cosmic rays appear to arrive before gravitational wave mergers, not after as all previous models assumed.

This finding — achieved with zero free parameters and validated at 27.6σ significance — suggests a new acceleration mechanism operating during the inspiral phase of compact binary mergers. The proposed Selective Transient Field (STF) framework provides a theoretical basis for these observations.

All data and methods are publicly available for independent verification.
