[59.02] Jet and Counterjet in the Seyfert Galaxy 3C 120

A. Sadun, S. Snaith (Agnes Scott Coll.)

We report on the unusual morphology of the 15th magnitude Seyfert galaxy 3C 120. This galaxy is quite active, varying in brightness in the visible as well as in the X-ray wavelengths, and in fact is categorized as an active galactic nucleus (AGN). It also shows extended structure in both wavelength regimes.

We have taken optical images in V, R, and I waveband filters to improve upon previous work done photographically. These images were taken with a CCD camera at Lowell Observatory's 42-inch telescope. Our images show both a jet and a (smaller) counterjet associated with this galaxy. We have used special image enhancement techniques to bring out these jets, and we measure their sizes, brightnesses, and colors.
