Explosions and bursts near black holes and neutron stars

Short-term explosive phenomena near black holes and neutron stars are often a signpost for extreme astrophysics. We investigate those explosions and the accompanying radiation and particles. We zoom in, amongst others, on Fast Radio Bursts, Gamma-ray Bursts, and X-ray transients. We also observe the steady emission from jets in the active nuclei of galaxies.

The supernova remnant Cassiopeia A (Cas A) as observed by the Chandra X-ray Observatory. Cas A is one
of the youngest supernova remnants, with an age of about 340 yr old. 
Different colors in this image correspond to differently freshly synthesised elements:
red is oxygen-rich gas, green silicon-rich, and blue is iron-rich. The small dot near the center is the neutron star
that was created during the supernova event.
The size of this remnant is about 5 arcminutes, corresponding to 5 parsec (15 light years).

Those jets are thought to be a major driver in halting massive galaxy growth. We work in close collaboration with GRavitation AstroParticle Physics Amsterdam (GRAPPA). In the coming decade, we want to combine gravitational-wave astronomy with observations of explosions and bursts. We want to know more about the nature of black-hole feedback into their environments, about Fast Radio Bursts and about new exotic objects that have not even been discovered yet.
