A Gravitational Mechanism for the Acceleration of Ultrarelativistic Particles
(arXiv, 200503)Imagine a swarm of free particles near a point P outside a gravitating mass M and a free reference particle at P that is on a radial escape trajectory away from M. Relative to this reference particle and in a Fermi normal ... 
Gravitomagnetic Accelerators
(arXiv, 201005)We study a simple class of timedependent rotating Ricciflat cylindrically symmetric spacetime manifolds whose geodesics admit gravitomagnetic jets. The helical paths of free test particles in these jets up and down ... 
Gravitomagnetic Jets
(arXiv, 201008)We present a family of dynamic rotating cylindrically symmetric Ricciflat gravitational fields whose geodesic motions have the structure of gravitomagnetic jets. These correspond to helical motions of free test particles ... 
Ultrarelativistic motion: inertial and tidal effects in Fermi coordinates
(Institute of Physics, 200412)Fermi coordinates are the natural generalization of inertial Cartesian coordinates to accelerated systems and gravitational fields. We study themotion of ultrarelativistic particles and light rays in Fermi coordinates ...
