Centrifugal instability of compressible flows and the hydrodynamic stability of accretion disks
Serguei S. Komissarov, Konstantinos N. Gourgouliatos
A recent analysis of the centrifugal instability in the case of pressure-supported compressible relativistic rotation, with application to astrophysical jets, yielded a generalisat…
Parametric instability of Alfvén wave packets
S. S Komissarov
Parametric instability of Alfvén wave packets with monochromatic carrier wave in low- plasma is studied using one-dimensional magnetohydrodynamic simulations. The results show s…
A splitting method for numerical relativistic magnetohydrodynamics
Serguei Komissarov, David Phillips
We describe a novel splitting approach to numerical relativistic magnetohydrodynamics (RMHD) designed to expand its applicability to the domain of ultra-high magnetisation (high-$σ…
An operator-splitting numerical scheme for relativistic magnetohydrodynamics
David Phillips, Serguei Komissarov
We describe a novel operator-splitting approach to numerical relativistic magnetohydrodynamics designed to expand its applicability to the domain of ultra-high magnetisation. In th…
Electrically-charged black holes and the Blandford-Znajek mechanism
Serguei S. Komissarov
Recently, it was claimed that accretion of electric charge by a black hole rotating in an aligned external magnetic field results in a "dead" vacuum magnetosphere, where the electr…
Magnetic inhibition of the recollimation instability in relativistic jets
Jin Matsumoto, Serguei S. Komissarov, Konstantinos N. Gourgouliatos
In this paper, we describe the results of three-dimensional relativistic magnetohydrodynamic simulations aimed at probing the role of regular magnetic field on the development of t…
