Jets in Extragalactic Radio Sources
Science, 1984Observations now require that there be a continuous supply of energy to the giant extragalactic radio sources. These observations also suggest that this energy input may be in the form of streams or jets of gas emanating from the centers of galaxies and quasi-stellar objects. Current data indicate that the large-scale jet structures are not moving with

Most radio sources are two-sided, but a minority appear onesided, 3C273 being the first-known and brightest example. There is no agreement1–4 on whether such sources are intrinsically one-sided, or are normal double sources, one half of which is hidden by Doppler effects.

The structure of the radio jets in 3C449
Nature, 1979High resolution observations of 3C449 show the presence of two highly collimated symmetric jets on each side of an unresolved core. The jets show considerable fine structure and polarisation. Measurements of the depolarisation suggest internal densities of ∼0.02 cm−3 and flow velocities of ≳1,000 km s−1.

The radio jet of the quasar 3C273
Nature, 1985Although 3C273 was was one of the first quasars to be identified1, the extended feature 3C273A, which can be detected at radio2,3, optical4,5 and X-ray wavelengths6, remains an enigma. The source is an extreme example of a one-sided radio source (3C273A has no detectable counter component2) and this fact, coupled with the presence of the optical ...
