The Large Magellanic Cloud as a source of the highest energy cosmic rays
Roger Clay, Tadeusz Wibig
The Pierre Auger Observatory has published properties of the 100 highest-energy cosmic ray events (to energies above 100 EeV) which it recorded over a 17 year period. We have exami…
Advancing the Landscape of Multimessenger Science in the Next Decade
Kristi Engel, Tiffany Lewis, Marco Stein Muzio +91
The last decade has brought about a profound transformation in multimessenger science. Ten years ago, facilities had been built or were under construction that would eventually dis…
Connections: the relationships between Neolithic and Bronze Age Megalithic Astronomy in Britain
Gail Higginbottom, Roger Clay
It has already been empirically verified that for many Bronze Age monuments erected in Scotland between 1400-900 BC, there was a concerted effort on behalf of the builders to align…
Origins of Megalithic Astronomy in Britain
Gail Higginbottom, Roger Clay
By c. 3000 BC, in the late Neolithic, there had been a significant change in the way people materialized their cosmology across Scotland with the introduction of free-standing ston…
Exploring the High-Energy Cosmic Ray Spectrum with a Toy Model of Cosmic Ray Diffusion
Roger Clay, Roland M. Crocker
We introduce a static toy model of the cosmic ray (CR) universe in which cosmic ray propagation is taken to be diffusive and cosmic ray sources are distributed randomly with a dens…
The 2025 June 01 Forbush Decrease measured over a range of primary cosmic ray energies
Roger Clay
The 2025 June 01 Forbush Decrease in the terrestrial ground-level flux of cosmic ray secondaries was recorded by many cosmic ray systems. This was the deepest such decrease, from t…
