The origin of jets emitted from black holes is not well understood; however, there are two possible energy sources: the accretion disk or the rotating black hole. Magnetohydrodynamic simulations show a well-defined jet that extracts energy from a black hole. If plasma near the black hole is threaded by large-scale magnetic flux, it will rotate with respect to asymptotic infinity, creating large magnetic stresses. These stresses are released as a relativistic jet at the expense of black hole… 
Black Hole Accretion
TLDR
Numerical simulations imply that the relativistic jets often seen from accreting black holes may be powered in part by the spin of the hole, as well as for both rotating holes and event horizons.
Simulation of Plasmoid Creation near a Rotating Black Hole
Relativistic jet phenomena are most often observed in the vicinity of black holes, where the surrounding plasma accretion plays an important role in the formation of these jets. The presence of a
Launching and Quenching of Black Hole Relativistic Jets at Low Accretion Rate
Relativistic jets are launched from black hole (BH) X-ray binaries and active galactic nuclei when the disk accretion rate is below a certain limit (i.e., when the ratio of the accretion rate to the
The Efficiency of Using Accretion Power of Kerr Black Holes
The efficiency of a rapidly spinning Kerr black hole to turn accretion power into observable power can attain 32 percent for the photon emission from the disk, as is well known, following the work of
Alignment of Magnetized Accretion Disks and Relativistic Jets with Spinning Black Holes
TLDR
The authors' simulations reveal a “magneto-spin alignment” mechanism that causes magnetized disks and jets to align with the BH spin near BHs and to reorient with the outer disk farther away, which has implications for the evolution of BH mass and spin, BH feedback on host galaxies, and resolved BH images.
Buoyancy and the Penrose process produce jets from rotating black holes
The exact mechanism by which astrophysical jets are formed is still unknown. It is believed that the necessary elements consist of a rotating (Kerr) black hole and a magnetized accreting plasma. We
Magnetically Driven Jets in the Kerr Metric
We compute a series of three-dimensional general relativistic magnetohydrodynamic simulations of accretion flows in the Kerr metric and investigate the properties of the resulting unbound outflows.

This article reports on three-dimensional (3-D) MHD simulations of non-rotating and rapidly rotating black holes and the adjacent black hole accretion disk magnetospheres. A particular emphasis is
String Mechanism for Relativistic Jet Formation
Here we present our latest studies of relativistic jet formation in the vicinity of a rotating black hole where the reconnection process has been taken into account. In order to simplify the problem,

We present a novel, relativistic accretion model for accretion onto a Schwarzschild black hole. This consists of a purely hydrodynamical mechanism in which, by breaking spherical symmetry, a radially
