Abstract: A follow - up X-ray study was made of the west lobe of the radio galaxy Fornax A, (NGC 1316) based on new ASCA observations made in 1997 for 98 ks, and incorporating the previous observation in 1994 for 39 ks.

But about seven per cent of radio galaxies produce more irregular «winged», or X-shaped, jets.

«We knew we could connect these two things, the lack of radio galaxies and the cold spot,» Brown says.

It took observations of radio galaxies, temperature, and a bit of conjecture.

The near - to mid-IR spectral energy distribution of the radio galaxy suggests the existence of a reddened, E (B - V) = 0.4 (+ / --RRB- 0.1 $, evolved stellar population of age > ~ 1.8 Gyr and mass 5 (+ / --RRB- 2 x 1e11 Msun.

Around the core of the radio galaxy NGC 4261 is a ring of dust and gas about 400 light years in diameter and the jets emerge perpendicular to the plane of the dust / gas ring.

Gas escaping along the magnetic field would produce the beams of electrons and gas seen in the jets to make the radio lobes of radio galaxies.
