well that’s why we filter the data. that’s how i made the radio images, you find what looks like it should be something and you add filters until the noise is at a consistent level with the background. this is usually done with Fourier transforms and it is fairly reliable, and we also usually check in multiple different spectra if possible if something isn’t visible on optical. That’s why a lot of composite images of nebulae and stuff are different wavelengths overlayed. we usually get a decent idea of if it is what we think it is. my research is focusing on finding low mass supermassive black holes though which have pretty significant radio signatures that we r looking for and things like that do things that couldn’t really be caused by anything else per GR
