Until now, the biggest supermassive black holes — those with masses around 10 billion times that of our sun — have been found at the cores of very large galaxies in regions loaded with other large galaxies.

Binary black holes are expected to be common in large galaxies, since galaxies are thought to grow by merging with other galaxies, each of which would presumably bring a central black hole with it.

Observations of two galaxies made with the National Science Foundation - funded Atacama Large Millimeter / submillimeter Array (ALMA) radio telescope suggest that large galaxies formed faster than scientists had previously thought.

There is abundant evidence that supermassive black holes with a mass of millions or billions of Suns dwell at the centres of most medium - to - large galaxies.

For decades astronomers have used computer models to predict how these dwarf galaxies should orbit large galaxies.

Another experiment there, the South Pole Telescope, reported finding B - mode polarization last year, although the signal it saw was at a different angular scale across the sky and was clearly due to the known process of gravitational lensing (a warping of light caused by massive objects) of the CMB by large galaxies, rather than the primordial gravitational waves seen here.

Before LIGO's detections, astronomers only had definitive observations of two varieties of black holes: ones that form from stars that were thought to top out around 20 solar masses; and, at the cores of large galaxies, supermassive black holes of still - uncertain provenance containing millions or billions of times the mass of the sun.

But new observations by Herschel, a far infrared space observatory operated by the European Space Agency, show that massive elliptical galaxies can form from the merger of two large galaxies.

Herschel spotted two large galaxies — 11 billion light - years away — in close proximity to one another, both of them making new stars at a much higher rate than most galaxies from that cosmic period.

Whereas the «loudness» of each chirp has clearly conveyed each event's distance from us, LIGO's twin stations can at present only vaguely constrain their celestial sources, which may lie anywhere within huge swaths of the heavens containing thousands upon thousands of large galaxies.

Within the hearts of large galaxies lurk supermassive black holes weighing hundreds of millions or billions of solar masses.

The only way to make the quasars so bright, astronomers believe, is for supermassive black holes to devour gas at the hearts of large galaxies.

Most large galaxies we see have supermassive black holes at their centres.

Over billions of years, these mergers continued, eventually producing the large galaxies and clusters of galaxies we see in the Universe today.

Gigantic black holes are at home in the nuclei of large galaxies all around us.
