«We were really concentrating on studying the dust in the filaments with SPIRE, and out pops these two bright emission lines exactly where we see the dust shining,» says Dr Gomez. (sciencedaily.com)
This technique, however, normally prevents astronomers from seeing the actual light emitted by the galaxy, which is overwhelmed by the much brighter emission from the background quasar. (sciencedaily.com)
Many distant galaxies have supermassive black holes at their cores, and those black holes power «central engines» that produce bright emission. (public.nrao.edu)
