So I've skimmed certain papers several years ago indicating that radio jets and other accretion-related emissions from black holes can be superluminal.
Is this true, or is this just the relative motion of particles in some medium other than vacuum that exceeds the speed of light?
I'm assuming that detecting these involves detecting cherenkov radiation?
Sorry if this seems somewhat newbish, I'm hoping someone with more expertise in the field can shed some light on this. Thanks
