Synchroton radiation extends into the radio wave spectrum. Therefore galaxies formed through this mechanism should be able to emit radio waves.
Radio wave emissions however are an exclusive property of elliptical galaxies.

On synchrotron radiation (Section 4.1, page 123) he says:

Essentially three types of spectra are found. Names such as cyclotron emission and magnetobremsstrahlung are used to describe the emission from nonrelativistic and mildly relativistic electron energies, whereas the name synchrotron radiation is traditionally reserved for highly relativistic electrons because it was first observed in 1948 in electron synchrotons

So, it would seem from this that not all plasmas exhibit synchroton radiation .. only 'highly relativistic electron emissions' ? (I'm not using his arguments to defend rather, I'm questioning what he's said here).
Seems to be another dissection of Plasma types ..
