Little Galaxies Have Black Holes Too
From the American Astronomical Society Meeting in Seattle: A team represented by Victor Debattista from University of Washington has found a supermassive Black Hole at the centre of a dwarf galaxy. The galaxy VCC128 is 54 million light-years away in our Virgo Cluster, and has only 1% of our galaxy's mass. The team found the Black Hole by sifting through archival Hubble Space Telescope data. Their poster was presented Sunday, for these days even big discoveries are presented as posters.
The news in year 007 gets better and better. We saw just last week that, as predicted, globulars contain Black Holes. Dwarf galaxies are thought to develop from globular clusters. This supermassive Black Hole has a mass between 1 million and 50 million solar masses. In the right photo it is orbited by a ring of stars. "It had been speculated that dwarf galaxies like this could not make black holes," Debattista said. Perhaps the Black Hole was there before the galaxy.
