Title: Survey of Energetic Particles Viewed by Parker Solar Probe

Abstract:
Since 2018, Parker Solar Probe has been sampling a largely unexplored regime near the sun, achieving a record-setting closest approach of 3.83 million miles (< 9 solar radii) from the solar surface on Dec. 24, 2024. During this time, the Integrated Science Investigation of the Sun (ISOIS) instrument suite has returned measurements of spatial and energy distributions of solar energetic particles in the transition from Solar Cycle 24 to 25 along its highly-elliptical orbit comprised of now 24 approaches to the sun. Here we survey key findings from the ISOIS energetic particle observations such as the radial and spectral evolution of cosmic rays, characteristics of widespread solar energetic particle events, multi-spacecraft perspectives of large-CMEs and stream interaction regions, and interactions with various types of plasma and magnetic structures, emphasizing new insights gained about particle transport and acceleration near the sun.
