About this Image

This image shows the radio emission from relativistic streams of high energy particles generated by the quasar. Astronomers believe that the jets are fueled by material accreting onto a super-massive black hole at the center of the host galaxy (not shown in this image). The high energy particles are confined to remarkably well collimated jets, and are shot into extragalactic space at speeds approaching the speed of light, where they eventually balloon into massive radio lobes. The overall linear size of the radio structure is 159 kpc, for a Hubble constant of 100 km/s/Mpc. There is a recessed hot spot complex in the West lobe, and periodic knot (shock?) structure in the jet.

Investigator(s):  Alan H. Bridle, David H. Hough, Colin J. Lonsdale, Jack O. Burns, and Robert A. Laing
