Do jets precess… or even move at all?
C Nixon, A King - The Astrophysical Journal Letters, 2013 - iopscience.iop.org
Observations of accreting black holes often provoke suggestions that their jets precess. The
precession is usually supposed to result from a combination of the Lense–Thirring effect and …
