Abstract: Extragalactic jets are very prowerful (probably the most in the universe) objects. They are clearly visible in radio wavelengths, but for some peculiar and famous of them, an optical counterpart is visible. The jets are supposed to be produced by extremely powerful central engines (black holes). It is very interesting to see a galaxy with a jet which is larger than the galaxy itself ! An image processing would allow us to see more clearly the jet. We propose to image three extragalactic jets, in B, R and I bands. The jets to image are 2C273, M84, and M87. (We've seen that m87 is already proposed in P5).

Comments by OPC

General Comments: An interesting project making use of the imaging capabilities available for Astronomy On-Line.

Visibility:The objects are visible at the end of the night.

Special Comments: Unfortunately, the moon is nearly full now, and the sky background will be bright, especially for the images in B; the faint jets will probably be diluted in the background brightness.

Expected time consumption (including overhead): About 2 hours.

Proposed facility:OHP, Wendelstein, IAC 80, or the Dutch telescope at La Silla.
