Infinite efficiency of collisional Penrose process: Can over-spinning Kerr geometry be the source of ultra-high-energy cosmic rays and neutrinos ?
Mandar Patil, Tomohiro Harada, Ken-ichi Nakao +2
The origin of the ultra-high-energy particles we receive on the Earth from the outer space such as EeV cosmic rays and PeV neutrinos remains an enigma. All mechanisms known to us c…

Timescale for trans-Planckian collisions in Kerr spacetime
Mandar Patil, Pankaj S. Joshi, Ken-ichi Nakao +2
We make a critical comparison between ultra-high energy particle collisions around an extremal Kerr black hole and that around an over-spinning Kerr singularity, mainly focusing on…
