Particle acceleration to extreme energies in cosmic sources

Paris, September 13th - 16th, 2016

The physics of particle acceleration in powerful relativistic astrophysical objects, such as gamma-ray bursts, blazars, pulsar winds etc. represents one of the cornerstones of modern theoretical multi-messenger astroparticle physics and high energy astrophysics. While non-thermal spectra are routinely observed over a wide range of frequencies, in a variety of astrophysical objects, only very few sources seem capable of accelerating particles to energies well in excess of a PeV (1015 eV). However, no such source has been clearly identified so far on observational grounds...

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.

Participation is upon invitation only.
