http://www.propulsionpolymers.com/radioastronomy/galactic_plane.pngThere's lumpiness due both to receiving system instability, and the fact that the galactic background radiation is not uniformly distributed in intensity. Around 16:20 or so, there's some interference from the Sun, since it transited only 2 beam-widths above where I was pointing. I annotated it with TGIF.
The quasi-discrete source at the galactic center is driven by a postulated black hole. The physics are complicated, but part of the emission is thermal, due to heating of the surrounding gas and dust by gamma and x-rays coming out of
the event horizon around the black hole as matter falls into it.
