We present a family of dynamic rotating cylindrically symmetric Ricci-flat gravitational fields whose geodesic motions have the structure of gravitomagnetic jets. These correspond to helical motions of free test particles up and down parallel to the axis of cylindrical symmetry and are reminiscent of the motion of test charges in a magnetic field. The speed of a test particle in a gravitomagnetic jet asymptotically approaches the speed of light. Moreover, numerical evidence suggests that jets are attractors. The possible implications of our results for the role of gravitomagnetism in the formation of astrophysical jets are briefly discussed.

  1. Cosmic Jets in General Relativity

    gr-qc 2025-06 conditional novelty 6.0 of 10

    Free particles and scalar waves in Kasner and plane-wave spacetimes asymptotically align into jets that move at nearly the speed of light relative to fiducial observers.

  2. Elliptically Polarized Plane Gravitational Waves

    gr-qc 2025-01 accept novelty 6.0 of 10

    Exact elliptically polarized plane gravitational wave solutions exhibit a cosmic jet effect: generic timelike and null geodesics asymptotically align with the propagation direction at speed c.
