Phantom Crossing with Quintom Models
L. W. K. Goh, A. N. Taylor
We develop a two-scalar field quintom model, which utilises both a quintessence-like and a phantom-like scalar field, enabling a smooth and stable transition across the phan…

Cosmic ray transport and acceleration with magnetic mirroring
A. R. Bell, J. H. Matthews, A. M. Taylor +1
We analyse the transport of cosmic rays (CR) in magnetic fields that are structured on scales greater than the CR Larmor radius. We solve the Vlasov-Fokker-Planck (VFP) equation fo…
