An article published in the journal “Science” describes a study of the galaxy W2246-0526, the brightest known. A team of researchers used the ALMA radio telescope to examine it by uncovering streams of materials as they are stripped from three smaller galaxies orbiting it. In one case a “tidal tail” is generated, a large stram of materials that connects W2246-0526 with one of its satellites. According to an article published in “The Astrophysical Journal” the supermassive black hole at its center has a mass that’s about 4 billion times the Sun’s.
