The following links & excerpts of the two sets of paired galaxies travelling on their space voyage together show these also to be consistent with our theories. Another factor supporting our theory that the central astrophysical object is not a ‘black hole’ is the direct correlation in the majority of cases of the determined ‘mass of the black hole’ to the mass of the galaxy and in particular the central part or bulge. It would be highly improbable for black holes forming in the usual way to coalesce together to form massive structures randomly that correlate with the mass of their galaxy. sciencedaily/releases/2012/09/120906092527.htm Elliptical & Spiral pair of galaxies touring universe together ‘Odd Galaxy Couple on Space Voyage’ Arp 116 is composed of a giant elliptical galaxy known as Messier 60 (or M60) and a much smaller spiral galaxy, NGC 4647. M60 is the third brightest galaxy in the Virgo cluster of galaxies, a collection of more than 1,300 galaxies. M60 has a diameter of 120,000 light-years and a mass of about one trillion times that of the Sun. A huge black hole of 4.5 billion solar masses lies at its center, one of the most massive black holes ever found. The faint bluish spiral galaxy NGC 4647 is about two-thirds of M60 in size and much lower in mass -- roughly the size of our galaxy, the Milky Way. We also now know that super massive black holes are inexorably linked to the galaxies that encircle them. For example, the size of a super massive black hole appears to have a direct correlation to the galaxy where it exists. Almost a decade ago, researchers calculated that the mass of a super massive black hole appeared to have a constant relation to the mass of the central part of its galaxy, known as its bulge (think of the yolk in a fried egg). This 1 to 700 relationship supports the notion that the evolution and structure of a galaxy is closely tied to the scale of its black hole. sciencedaily/releases/2013/07/130702100927.htm Inseparable Galactic Twins Both are spiral galaxies, and are presented to our eyes face-on, so we are able to appreciate their distinctive shapes. On the left of the image, spiral galaxy PGC 9074 shows a bright bulge and two spiral arms tightly wound around the nucleus, features which have led scientists to classify it as a type Sa galaxy. Close by, PGC 9071 -- a type Sb galaxy -- although very similar and almost the same size as its neighbor, has a fainter bulge and a slightly different structure to its arms: their coils are further apart. The spiral arms of both objects clearly show dark patches of dust obscuring the light of the stars lying behind, mixed with bright blue clusters of hot, recently-formed stars. Older, cooler stars can be found in the glowing, compact yellowish bulge towards the center of the galaxy. The whole structure of each galaxy is surrounded by a much fainter round halo of old stars, some residing in globular clusters.
