Pictured here are VLA images of 8 radio galaxies at centimeter
wavelengths. The big radio galaxy on the left is Hydra A. Continuing
clockwise are PKS1246-410, 4C26.42, 3C129, PKS0745-191, 3C129.1, 3C84
and 3C295. All of these radio galaxies live in relatively rich
clusters of galaxies which partly explains the wide range of
morphologies. In fact, all of them are associated with a central
dominant elliptical galaxy except for 3C129 which is associated with a
more ordinary elliptical galaxy at the periphery of the cluster. The
angular resolution of these images is typically about 0.5", and the
sources range from 5 -- 100" in overall angular extent, or about
10-100 kpc in physical size.
The published images and information about them can be found in
papers listed at http://www.aoc.nrao.edu/~gtaylor/publist.html.

Pictured here are VLBA images of 4 Compact Symmetric Objects (CSOs)
at centimeter
wavelengths.
Based on measurements of the
expansion of the sources, the radio emission we are seeing is thought
to
be recent activity, about 1000 years old. So these are baby radio
galaxies. Some of them might grow up to look something like Cygnus A.
The long skinny source in the upper left is 1358+624; at center is
0402+379, at right is 0710+439 and at the bottom is 4C31.04.
All of these radio galaxies live in large elliptical galaxies.
The angular resolution of these images is typically about 1 mas, and the
sources range from 10 -- 100 mas in overall angular extent, or about
10 - 100 pc in physical size.
The published images and information about them can be found in
papers listed at http://www.aoc.nrao.edu/~gtaylor/publist.html.
