Particle acceleration to extreme energies in cosmic sources

Paris, September 13th - 16th, 2016

What are and where are the PeVatrons, sources of high energy cosmic rays and neutrinos? What is the main acceleration process at work in these sources?

This workshop, funded by the Programme National Hautes Énergies (PNHE), the Institut Lagrange de Paris (ILP) and the Institut d'Astrophysique de Paris (IAP), will address these questions. Gathering some well-known experts in this field of research, at the crossroads between the high energy, astroparticle and astro-plasma communities, it will cover the latest theoretical developments in understanding acceleration (including shocks, reconnection, turbulence etc.) as well as the phenomenology of particle acceleration in astrophysical sources.
