I am an associate professor, working in the field of high energy astrophysics. I work at the Anton Pannekoek Institute at the University of Amsterdam, I am a member of GRAPPA, a center of excellence on Astroparticle Physics, and affiliated with SRON Netherlands Institute of Space Research.

My current research focusses on the question of how efficiently cosmic rays are accelerated by supernova remnant shocks,  but I am also interested in, 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 active as both an observational (radio, X-rays and γ-rays), and theoretical researcher.

My scientific achievements include: providing first evidence for magnetic field amplification near super-nova remnant shocks; the first detection of 68 keV and 78 keV line emission from radio-active titanium; the discovery of the Si-rich X-ray jets in Cas A; showing that magnetars magnetic fields are not caused by rapid initial rotation. My research has been supported by several grants, among others a NASA Chandra Fellowship (2000) and NWO Vidi fellowship (2006).

Currently I am a member of the H.E.S.S. collaboration operating the ground-based H.E.S.S. Imaging Cherenkov Telescope in Namibia, the CTA Consortium, building the future Cherenkov Telescope Array, and I am member of the Galactic Science Working Group of the LOFAR Surveys Key Science Program. I am also in the ESA science definition team for the pre-selected M4 mission, XIPE, an X-ray polarisation mission.

The birth of multi-messenger astrophysics

October 16, 2017

Taken from the H.E.S.S. page: https://www.mpi-hd.mpg.de/hfm/HESS/

On August 17, 2017, the gravitational wave interferometers Advanced Ligo and Advanced Virgo recorded a signal from the merger of a binary neutron star system, a type of signal that had never been seen before. Complementing this exciting discovery, a large variety of electromagnetic
observations were able to record signals from the same event. They range from the detection of a gamma-ray burst about 2 seconds after the gravitational wave event, over near-infrared, optical and UV emission from decay of radioactive nuclei created in the resulting kilonova to X-ray and radio emissions detected several days and weeks after the event. This first and extremely successful observation campaign is marking the beginning of truly multi-messenger astrophysics.

The H.E.S.S. target selection identified regions of high probability to find a counterpart of the gravitational wave event. The first of these regions contained the counterpart SSS17a that has been identified in the optical domain several hours after our observations. We can therefore present the first data obtained by a ground-based pointing instrument on this object. A subsequent monitoring campaign with the H.E.S.S. telescopes extended over several days, covering timescales from 0.22 to 5.2 days and energy ranges between 270 GeV to 8.55 TeV. No significant gamma-ray emission has been found. The derived upper limits on the very-high-energy gamma-ray flux for the first time constrain non-thermal, high-energy emission following the merger of a confirmed binary neutron star system.
