The paper has now been accepted for publication in MNRAS. See the full press release or just head over to the simulation movie made by co-Author Dr. Matthew Liska.
The picture of our very own black hole is finally out. Glad to have played a small role in its interpretation in the BlackHoleCam and EventHorizonTelescope collaborations. See here for all the 10(!!) papers. But if you are in a hurry check out paper V which shows the large role of computational physics in today's discovery.
With numerical simulations of accreting compact objects, we study the transport of angular momentum and magnetic field, the ejection of relativistic jets and model horizon scale structure observed by the Event Horizon Telescope.
PWN are unique laboratories to investigate relativistic plasma. Among other things, they teach us about fluid instabilities, relativistic shocks, magnetic dissipation, particle acceleration and turbulent processes.
By modeling the non-thermal radiation emitted from astrophysical plasma, we extract important source parameters and understand particle energetization in a regime impossible to study in the laboratory.
The main tools of my research
Build upon the MPI-AMRVAC framework, the Black Hole Accretion Code solves the equations of general relativistic magnetohydrodynamics (GRMHD). Its modular design allows to simulate not only Einstein gravity, but also Black Holes in arbitrary metric theories of gravity and other compact objects. BHAC is the workhorse GRMHD-code for the blackholecam collaboration and provides source models for the Event Horizon Telescope Collaboration.
With a current focus on solar- and non-relativistic astrophysical applications, MPI-AMRVAC offers a wide range of advanced features for the solution of (quasi-) conservation laws. Adaptive grids can be employed in cartesian, cylindrical and (stretched) spherical geometries. The code has been modernized recently and the documentation is frequently updated.
