An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate. Their findings are published in December's first issue of the journal Astronomy and Astrophysics. http://www.physorg.com/news179690529.html Space & Earth Thu, 10 Dec 2009 18:40:01 EST news179690529 (PhysOrg.com) -- Astronomers at the University of Bonn have clarified the connection between black holes at the centre of galaxy clusters and surrounding gas, which serves them as "food". The scientists have produced a ground-breaking study of what could be called "cosmic feeding". It has now been published in the prestigious scientific journal Astronomy and Astrophysics. http://www.physorg.com/news171293489.html Space & Earth Fri, 04 Sep 2009 14:33:18 EST news171293489 (PhysOrg.com) -- The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. By analyzing the spectrum of light emitted in the GRB afterglow, the researchers are gleaning insights into an active stellar nursery in a galaxy so far away it appears as it was 10 billion years ago. http://www.physorg.com/news150478619.html Space & Earth Tue, 06 Jan 2009 15:36:59 EST news150478619
