Animation of Galaxy Merger SDSS J1254+0846

This movie of a numerical simulation shows a galaxy merger similar to SDSS J1254+0846 over a time span of 3.6 billion years (Gyr). At 2.33 Gyr the two model galaxies and their quasars resemble the image observed with the Magellan telescope. Credit: T.J. Cox/Carnegie Institution
