Dear Colleague,
This is a reminder that the registration and abstract submission are
open for the E1.16 session entitled “Origin of Cosmic Rays” at the 43rd
COSPAR Scientific Assembly to be held in Sydney, Australia, 15-22 August
2020.
Scope
———
Cosmic rays (CRs) are the only pieces of matter available to us that come from large Galactic and extragalactic distances. Nowadays they are complemented by the samples of solid interstellar grains returned to Earth by spacecraft. The spectra of CR species, composition, and direction at the highest energies provide invaluable information about their origin and propagation history. The bulk of Galactic CRs is associated with the most energetic events such as supernova explosions, but some fraction may also come from pulsars and interstellar shocks, and perhaps from more exotic and less studied processes. The origin of extragalactic CRs is still a mystery with speculations ranging from nuclei of active galaxies to gamma-ray bursts and primordial shocks.
Last decade was generous on discoveries in astrophysics of CRs, thanks to new experimental techniques and technological breakthroughs integrated into the instruments launched to the top of the atmosphere and into space. Among them PAMELA, Fermi-LAT, AMS-02, CALET, DAMPE, NUCLEON, and ISS-CREAM. Ground-based gamma-ray telescopes, such as H.E.S.S., MAGIC, and VERITAS, and water Cherenkov detector HAWC, proved to be able to probe CR fluxes in distant locations. Besides, we witnessed the birth of gravitational wave astronomy (LIGO and Virgo) and the first astrophysical neutrinos detected by IceCube. Meanwhile, instruments designed and built using the technology of 1970s, Voyager 1, 2 spacecraft, are also continuing to surprise us by beaming unique information from interstellar space. Orbiting near the L1 Lagrange point since 1997, ACE/CRIS is benefiting from the long exposure time dicovering rare clues to the origin of the local Galaxy (e.g., the
detection of a handful of Fe60 nuclei) yet providing information on variations of CRs during several solar cycles. Spectacular recent discoveries in multi-messenger astrophysics and new measurements of spectra of CR species and their isotopic composition will be discussed during this event. Direct measurements of gamma-ray emission from a number of particle accelerators and from interstellar space, new CR results at very-high and ultra-high energies, as well as new controversies and alternative theoretical models will also be highlighted.
This session encourages presentations of new experimental approaches and theoretical analyses directed towards answering questions related to the origins of cosmic messengers.
