Astrophysical jets research

Astrophysical jets are physical conduits along which mass, momentum, energy and magnetic flux are channeled from stellar, galactic and extragalactic objects to the outer medium.
Fast, axially collimated outflows, or 'jets', are ubiquitous in astrophysics.
They flow from most classes of compact objects that spin and/or accrete matter from their surroundings.
We also now realize that jets play an important feedback role in the evolution of their host systems.
The jet was first discovered in 1918 by H.
Curtis, who described it as a "curious straight ray" extending from the galactic nucleus.
Jets are associated with black holes with very different masses.
