What Kinds of Objects Are Capable of Creating Jets?

The galaxy is rotating, ye yathat right hand rule, you're going to see material blasting up out of the centre of the galaxy and also down out of the centres. What kinds of objects are capable of generating these jets? At the most pathetic level, we have very young stars called ttory stars. For dead stars, you have neutron stars and bigger. And when i say an bigger i mean like all black holes all the way up to supermassive black holes are capable of having gents. So you can have a full fledged galaxy that has the exact same, not entirely well understood physics as that neutron star.
