I am an associate professor, working in the field of high energy astrophysics. I am located at the Astronomical Institute Anton Pannekoek at the University of Amsterdam and I am a member of GRAPPA.

My research focusses on cosmic ray acceleration by supernova remnants, but I am also interested, and have published on, other aspects of supernova remnants, and on isolated neutron stars, magnetars, pulsar wind nebulae, clusters of galaxies and AGN.

I am a member of the H.E.S.S. consortium and involved in the future Cherenkov observatory CTA.

The many sides of RCW 86: a type Ia supernova remnant evolving in its progenitor's wind bubble

Sjors Broersen and collaborators published a paper on the X-ray emission of the peculiar supernova remnant RCW 86, the probably remnant of a supernova seen in AD 185.

The study contains high resolution X-ray spectroscopy as well as a study of hydrodynamics of this remnant evolving in a wind blown bubble.

The main conclusions are:

  1. -RCW 86 is confirmed as a remnant in a wind cavity

  2. -The iron emission indicates an iron content consistent with a Type Ia supernova origin

  3. -Type Ia origin means a scenario with a white dwarf with an accretion wind

  4. -Shock velocities changed/are changing dramatically over a period of 100 yr

  5. -The ejecta plasma is very hot (>10^9K)

The study will be published in MNRAS and can be found here: http://arxiv.org/abs/1404.5434
