Seminario Dr. Emanuele Greco - The impact of magnetic turbulence on the non thermal X-ray radiation from Supernova Remnants
7 February 2024,16:30- Physical Seminar Series Announcement!
Supernova Remnants (SNRs), the diffuse leftover of Supernova explosions,
are characterised by bright non thermal radiation typically emitted in form
of synchrotron radiation. The mechanism usually invoked to explain the
observed emission is the Diffusive Shock Acceleration (DSA), according to
which electrons are accelerated up to TeV energies in the shock. In the DSA
framework a crucial role is played by magnetic turbulence, responsible for
the confinement of the electrons close to the shock front. In this talk, I
will go through the currently known features of X-ray synchrotron radiation
in SNRs and some of the open issues. I will focus especially on the
observational perspective, discussing recent results from the first X-ray
polarimeter telescope, IXPE, and other telescopes, the implications for the
magnetic turbulence in SNRs and future prospects.
Venue: Seminar Room, Department of Physics, Building 31 C, 4th Floor.
