The Picture Gallery

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. Specific questions about any of the above radio galaxies can be addressed to gtaylor@nrao.edu.

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.
