HTTP:: Double Nucleus Galaxies More Common than Thought
--------
Established astronomical knowledge had it that galaxies with two nuclei were very rare. Experts believed that small galaxies had one made up of a star cluster, whereas the more massive ones had a black hole at their cores. But a new study comes to prove that the double-nucleus galaxy is, in fact, not that rare of an occurrence. In the research, which analyzed 50 regular galaxies, 12 were found to have both a black hole and a star cluster at their cores. A paper detailing the finds appears in the latest issue of the scientific journal Monthly Notices of the Royal Astronomical Society, ScienceDaily reports. In charge of the new investigation were Swinburne University of Technology (SUT) Associate Professor Alister Graham and Dr. Lee Spitler. Much to their amazement, they discovered that it was not at all uncommon for regular galaxies to have a black hole at their cores, as well as a cluster containing up to ten million stars around them. The presence of such a significant n!
umber of double-nucleus galaxies increases the chance of some peculiar astronomical phenomena occurring, Graham reveals. One example consists of black holes beginning to consume nearby stars. “When stars get too close to massive black holes, the gravitational attraction is such that they can be devoured. When you’ve got ...
