An article published in “The Astrophysical Journal” reports a study on a dusty early galaxy known as MAMBO-9. A team of researchers led by Caitlin Casey of the University of Texas at Austin used the ALMA radio telescope to study this galaxy about 13 billion light years away and its star formation rate much higher than the Milky Way’s. The observations showed that actually they’re two galaxies during a merger. That’s all useful to understand the role of dusty galaxies like that one in the evolution of the universe.
