Shock properties for solar energetic particle events with signatures of inverse velocity arrival
A. Kouloumvakos, D. Lario, G. M. Mason +20
We present a detailed investigation of the shock properties associated with solar energetic particle (SEP) events that exhibit a concave (``nose-like'') shape in their energy spect…

Parker Solar Probe observations of solar energetic particle (SEP) events with inverse velocity arrival (IVA) features
Zigong Xu, C. M. S. Cohen, R. A. Leske +21
In SEP events, velocity dispersion (VD) is characterized by the earlier arrival of faster, higher-energy particles relative to slower ones, assuming negligible acceleration time an…

Energy-dependent SEP Fe/O abundances during the May 2024 superstorm
G. D. Muro, C. M. S. Cohen, Z. Xu +16
During mid-May 2024, active region (AR) 13664 produced a series of M- and X-class flares along with several coronal mass ejections (CMEs) that resulted in exceptionally strong auro…
