... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... One characteristic of the ATCA dishes is that they are big by 3-mm standards. Indeed van Hoerner (1967) has considered the limits to the size of an antenna before various effects become significant. ... As the ATCA dishes are twice this, it is not surprise that the ATCA antenna gain and primary beam response varies as a result of thermal distortions. ... A gain/elevation correction will solve this - to first order at least. ... This might be an important effect for widefield imaging and mosaicing. ...
