"SuGAR 2018: Searching for the sources of galactic and extra galactic cosmic rays"

Brussels, 23 - 26 January 2018 (ULB - Campus Plaine - Solvay Room)

The goal of the workshop is to provide an updated overview of the long-standing enigma of the origin of galactic and extragalactic cosmic rays.

The SuGAR workshop will offer an opportunity to bring together leading experts exploring the physics of cosmic rays both from the experimental and theoretical point of view. The latest experimental results from gamma-ray (CTA, HAWC), neutrino astronomy (IceCube, KM3NeT), cosmic ray (Pierre Auger Observatory, Telescope Array, AMS-II, Lofar) and gravitational waves (LIGO, Virgo) experiments will be presented, as well as the latest developments in phenomenological interpretations and theoretical models. The interplay between subjects proposed in this workshop reflects the multi-messenger observational approach followed by the cosmic ray physics community. This workshop represents an excellent platform for discussion and exchange among researchers working in the wide field of astroparticle physics. The format of the workshop will allocate time for open discussions that will allow the participants to explore and discuss the experimental results and consequences of different theoretical models on the origin of cosmic rays and their acceleration and transport in the interstellar medium.

SuGAR 2018 is the third edition of a series of successful workshops, the latest of which took place in Geneva in January 2015.

Planned sessions include:
Galactic and extragalactic cosmic rays: spectrum / composition / anisotropy
Modeling: particle acceleration and propagation
Neutrino astronomy: highlights and future developments

Gamma-ray astronomy: highlights and future developments

Gravitational waves: highlights and future developments
