Largest Quasar Outflow Observed

  Virginia Tech physicists have discovered a quasar with the most energetic outflow ever seen, a finding that may answer questions about how the mass of a galaxy is linked to its central supermassive black hole mass and why there are so few large galaxies in the Universe. This artist’s impression shows the material ejected [continue reading]

Quasars Unveil New Era in the Expansion History of the Universe

  BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the Universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on [continue reading]
