I'm happy to announce that our paper led by NOVA VIA Postdoc Hector Olivares was just featured on science alert.
In the study, we conducted GRMHD simulations of accretion onto condensations of light bosons called
See the MNRAS paper for all the details!
Update: for a nice summary, see the following YouTube video by Anton Petrov.
With great please I can finally announce the release of BHAC v1.0 under the GPL3 license! You can find usage instructions and updated documentation at our new website bhac.science.
I'm really looking forward to the science coming out of the public code!
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.
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.
