Jakob van den Eijnden

I am a Warwick Prize Fellow in the Astronomy and Astrophysics Group at the University of Warwick. My interests cover many aspects of observational high-energy astrophysics, ranging from black hole variability and accreting neutron stars to jet formation and particle acceleration at astrophysical shocks. My main focus is on radio, X-ray, and sub-mm observations with observatories such as MeerKAT, the VLA, and ATCA (radio); NuSTAR, NICER, XMM-Newton, Chandra, and Swift (X-rays).

My research interests are, for a large part, united in the study of massive stars: either in binary systems with a compact object, or isolated and travelling through interstellar space at high velocities. In the former case, mass transfer can take place from the massive star unto the black hole or neutron star. In those systems, I study the formation of jet outflows and the scaling between their power and the properties of the compact object. In the case of isolated massive stars, I work on the shock they power in the interstellar medium, where particles may be accelerated up to extreme energies.

The image below shows a radio observation highlighting a unique combination of these two processes: a massive star in a binary with a neutron star, also creating a shock in the ISM (published in 2022Link opens in a new window).
