A beast with four tailsCambridge UK (SPX) Dec 01, 2011 The Milky Way galaxy continues to devour its small neighbouring dwarf galaxies and the evidence is spread out across the sky. A team of astronomers led by Sergey Koposov and Vasily Belokurov of Cambridge University recently discovered two streams of stars in the Southern Galactic hemisphere that were torn off the Sagittarius dwarf galaxy. This discovery came from analysing data from the latest Sloan Digital Sky Survey (SDSS-III) and was announced in a paper that connects these new streams with two previously known streams in the Northern Galactic hemisphere. "We have long known that when small dwarf galaxies fall into bigger galaxies, elongated streams, or tails, of stars are pulled out of the dwarf by the enormous tidal field," said Sergey Koposov. ... read more |
