… papers on energy-extraction processes near a Kerr blackhole immersed in a magnetic field.
A convenient formalism for discussing energy extraction by the Penrose process is presented…

… In this section we show that some of the crucial properties of the collisional Penrose process
… the range of possible energies for a fragment in the Penrose process resulting from the …

… ergosphere and energy extraction by the Penrose process in a … efficiency of the energy
extraction process greatly. Especially for … of the energy extraction by using the Penrose process. …

… We discuss also particle decay for static black holes, when the Penrose process is impossible.
Because of the absence of the ergoregion in the static case, scenarios of decay for static …

… We consider the electric Penrose process with a test particle dynamics in Sect. 3. We study
the geometrically thin Novikov–Thorne model for the accretion disk around the black hole in …

… Penrose process, the black hole spin energy is extracted causally due to the negative energy
at infinity (or just called "energy") of a particle caused by fission (Penrose 1969). Takahashi …

… For such an extraction, the existence of negative energies and … the Penrose process [6]
or its collisional analogue [7]. If the energy gain is unbounded, this is called the super-Penrose …

… a superradiant manner via an enhanced Penrose process. In particular, we find that the
regions from which energy and angular momentum can be extracted contain the axis of rotation …

… Penrose process was suggested by Penrose' in 1969 as a possible way of extracting rotational
