Giant Elliptical Galaxies seen forming in the early Universe
Dusty Galaxies From Early Universe In Throes Of Intense Burst Of Star
Formation "For many years it has been thought that these giant elliptical galaxies formed most of their stars at very early times in the Universe, within the first billion years after the Big Bang. However, very few examples of these very distant and very bright dusty sources have been found in submillimetre surveys, until the LESS collaboration completed their survey of a Full Moon-sized patch of sky in the southern hemisphere constellation of Fornax. Their survey is the largest and deepest of its kind in submillimetre radiation and reveals over a hundred galaxies that are forming stars at a prodigious rate. Working with their new map, the team identified one of the submillimetre sources as being associated with a star forming galaxy which is seen just 1 billion years after the Big Bang. This remarkable galaxy shows the signatures of both intense star formation and obscured black hole growth when the Universe was only 10 percent of its current age. Dr. Coppin and the LESS team suggest that there could be far more submillimetre galaxies lurking at these early times than had previously been thought. Dr Coppin comments, “The discovery of a larger number of such active galaxies at such an early time would be at odds with current galaxy formation models”." http://www.sciencedaily.com/releases...0422085832.htm |

Is this a new instrument that has come online? David A. Smith |

I don't know how new it is, but it should be relatively new. New enough that I think they blew it up in the Quantum of Solace James Bond movie. :-) Yousuf Khan |
