Neutrino current in a gravitational plane wave collision background
Donato Bini, Christian Cherubini, Gianluca Cruciani +1
The behaviour of a massless Dirac field on a general spacetime background representing two colliding gravitational plane waves is discussed in the Newman-Penrose formalism. The geo…
Second Order Scalar Invariants of the Riemann Tensor: Applications to Black Hole Spacetimes
C. Cherubini, D. Bini, S. Capozziello +1
We discuss the Kretschmann, Chern-Pontryagin and Euler invariants among the second order scalar invariants of the Riemann tensor in any spacetime in the Newman-Penrose formalism an…
Massless field perturbations and gravitomagnetism in the Kerr-Taub-NUT spacetime
Donato Bini, Christian Cherubini, Robert T. Jantzen +1
A single master equation is given describing spin test fields that are gauge- and tetrad-invariant perturbations of the Kerr-Taub-NUT spacetime representing a source with m…
Gravitomagnetism in the Kerr-Newman-Taub-NUT spacetime
Donato Bini, Christian Cherubini, Robert T. Jantzen +1
We study the motion of test particles and electromagnetic waves in the Kerr-Newman-Taub-NUT spacetime in order to elucidate some of the effects associated with the gravitomagnetic…
