As in computing, naming things is hard. The redshifting things are mostly molecular gas clouds which we would expect would orbit in a Keplerian fashion given the overall distribution of luminous matter and occluding/extinguishing dust visible in galaxies. Astrophysicists love hydrogen gas clouds because they ionize easily from background emitters (stars, quasars) producing very sharp spectral lines, and you can pick up their changes by…</p><p><a href="https://hackerpaper.kaipfister.de/p/astro-ph_9701131/">Paper and discussion history</a>.
