Kinematic restrictions on particle collisions near extremal black holes: A unified picture
Filip Hejda, Jiří Bičák
In 2009, Banados, Silk and West (BSW) pointed out the possibility of having an unbounded limit of centre-of-mass collision energy for test particles in the field of an extremal Ker…

Extremal Black Holes in Strong Magnetic Fields: Near-Horizon Geometries and Meissner Effect
Filip Hejda, Jiří Bičák
For extremal black holes, one can construct simpler, limiting spacetimes that describe the geometry near degenerate horizons. Since these spacetimes are known to have enhanced symm…
