Description

The evidence for supernova remnants as the main sources for Galactic cosmic rays has accumulated over the past decades. However, the physics of the acceleration mechanism is still unclear. In particular, there is a lack of empirical data to test current shock acceleration models. RCW 86 is an excellent source to test these models, as the shock velocities of the remnant vary by an order of magnitude and parts of the remnant have shown to be efficient accelerators. I will present our study of this remnant, thereby focusing on differences of the electron and proton temperatures behind the shock fronts and on measuring proper motions of various parts remnant. I will discuss these results in the context of cosmic-ray acceleration models.
