Q&A: Galaxies, Galaxy Clusters, AGN, and Quasars
Can you tell me where I could find pictures of quasars. I am
looking for one that is not strait. The pictures all show a
strait beam a million light years long. They show very little
drift. If a beam a million light years long took a million years
to form it should swirl and drift ? If they took seconds to form
they would look strait? When the beam extends outward from the
center of the galaxy do they pass through layers that match up
with other quasars in other galaxies?
We are assuming that you are referring to the jets that are
observed in connection with quasars, and active galactic
nuclei. These jets tend to be fairly straight as long as the
pressure in the jet is greater than that of the surrounding
gas. Then they twist and break up into fuzzy blobs.
In addition to the X-ray jets on our web site, you can view a
large collection of radio jets at:
Whether the jets match up with other quasars is
controversial, but most astrophysicists believe that such
matches are very likely coincidental.
