Scaled laboratory experiments explain the kink behavior of the Crab Nebula jet

Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The remarkable discovery by the Chandra X-Ray Observatory that the Crab nebula’s jet periodically changes direction provides a challenge to our understanding of astrophysical jet dynamics. To study the physics of this jet in the laboratory for the first time, we used high-power lasers to create a plasma jet that could be directly compared with the Crab nebula jet through well-defined physical scaling laws. Here we show that such a jet generates its own embedded toroidal magnetic fields; as it moves, plasma instabilities result in multiple deflections of the propagation direction, mimicking the kink behavior that has been observed in the Crab jet. The experiment is modeled with 3-dimensional numerical simulations that show exactly how instability develops and causes the kinks and resultant changes of direction in the jet. We expect that ' .
