How the Milky Way Got Its SpiralPittsburgh PA (SPX) Sep 21, 2011 The signature spiral arms of the Milky Way galaxy were likely formed by an epic collision between the Milky Way and the Sagittarius Dwarf galaxy, according to a University of Pittsburgh researcher and his collaborators, published in the prestigious British journal Nature. Supercomputer simulations by Christopher W. Purcell, postdoctoral research associate in the Department of Physics and Astronomy in Pitt's School of Arts and Sciences, and colleagues report their findings in a paper titled "The Sa ... read more |
