Discovery of Hot Oxygen Gas Streaming Away from Distant Galaxies: Witnessing the Final Stage of Galaxy Buildup
December 10, 2013
An international team of astronomers has used the Subaru Prime Focus Camera to make the first discovery of the large physical extent of energetic oxygen-gas outflows driven by a super-massive black hole and star formation. The team found 12 galaxies, 9 billion light years from Earth, that are expelling hot oxygen gas extending up to 250,000 light years beyond the galaxies' areas. These distant galaxies are probably in their final phase of growth, with star formation being quenched by the expulsion of gas needed to produce new stars...
Marching to the Beat: Subaru's FMOS Reveals the Well-Orchestrated Growth of Massive Galaxies in the Early Universe
December 5, 2013
Using the Fiber-Multi-Object Spectrograph (FMOS) mounted on the Subaru Telescope, a team of astronomers participating in the Cosmological Evolution Survey (COSMOS) has found that galaxies, over nine billion years ago, provided a nurturing environment for the birth of new stars at remarkable, orderly rates. Even at these early times, there are signs of maturation...
