Establishing a consistent local interstellar magnetic field direction using IBEX low-energy neutral atoms and galactic cosmic rays at ten orders of magnitude higher energy levels has wide-ranging implications for the structure of our heliosphere and is an important measurement to be making in tandem with the Voyager 1 spacecraft, which is in the process of passing beyond our heliosphere.
Two forms of radiation pose potential health risks to astronauts: a chronic low dose of galactic cosmic rays (GCRs) and the possibility of short-term exposures to the solar energetic particles (SEPs) associated with solar flares and coronal mass ejections.
Topics include the relation between magnetic energy and helicity, the hydrodynamics of colliding circumstellar bubbles, the stability of cosmic ray precursors, supernova remnants as the source of galactic cosmic rays, and polarimeters for HARPS and X-shooter.
Topics of the 22 invited talks include high-energy neutrino astronomy, the origin of galactic cosmic rays, the highest-energy cosmic rays, cosmic rays and gamma radiation from clusters of galaxies, gamma-ray blazars, non-thermal x-ray emission from supernova remnants, gamma-ray line astronomy, and neutrino telescopes.
