For the first time, the simulations showed that such tilted disks lead to
precessing jets that periodically change their direction in the sky.
An important reason
precessing jets were not discovered earlier is that 3 - D simulations of the region surrounding a rapidly spinning black hole require an enormous amount of computational power.
Not exact matches
K3 - 35, seen as a radio image (top left), also has
precessing gas
jets.
