Descripción

In the aftermath of the cataclysmic explosion of massive stars, a vast zoology of source type is observed such as Supernova Remnants (SNRs), pulsar wind nebulae, pulsars and ‘zombie’ pulsars. Due to high velocity shock-waves combined with a high magnetic field or fast rotation in the case of pulsars, an efficient particle acceleration is achieved in those objects which are believed to be significant contributors to the pool of Galactic cosmic rays.
This seminar will start with a short introduction on particle acceleration and SNR physics, present the current scientific questions, and what we’ve learned from high-energy observations in the recent years.

On a more technical note, I will also present a new analysis method to fully exploit the multi-dimensional (X, Y, Energy) nature of X-ray data. This blind source separation method draws from the most advanced signal processing techniques to capture and disentangle the wealth of information contained in deep archival observations.
