Observable acceleration of jets by a Kerr black hole
J. Gariel, N. O. Santos, Anzhong Wang
In the framework of a model based on the gravitational field of the Kerr black hole, we turn to investigate the kinematic behavior of extragalactic jets. We analytically calculate…
Kerr Geodesics Following the Axis of Symmetry
J. Gariel, N. O. Santos, Anzhong Wang
We present here the general expressions for the acceleration of massive test particles along the symmetry axis of the Kerr metric, and then study the main properties of this accele…
Unbound geodesics from the ergosphere and potential observability of debris from ultrahigh energy particle collisions
J. Gariel, N. O. Santos, J. Silk
Particle collisions in black hole ergoregions may result in extremely high center of mass energies that could probe new physics if escape to infinity were possible. Here we show th…
Unbound geodesics from the ergosphere and the M87 jet profile
J. Gariel, G. Marcilhacy, N. O. Santos
Assuming that the spin of the black hole, presumably located at the core of the active galactic nuclei Messier 87 (M87), takes the value which maximises the ergospheric volume…
Gravitational Model of High Energy Particles in a Collimated Jet
J. A. de Freitas Pacheco, J. Gariel, G. Marcilhacy +1
Observations suggest that relativistic particles play a fundamental role in the dynamics of jets emerging from active galactic nuclei as well as in their interaction with the intra…
Model of collimated jets with high energy particles
C. Barbachoux, J. Gariel, G. Marcilhacy +1
The increasing data set of precise observations of very energetic and collimated jets, with black hole (BH) as putative central engine, at different astrophysical scales and in var…
