Wed, 29 Dec 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111221 An international team of astronomers led by Masami Ouchi at the University of Tokyo has discovered a vigorous, star-forming galaxy that existed about 750 million years after the Big Bang. This galaxy, named GN-108036, was a remarkable source of star formation at the so-called "cosmic dawn", a very early time in cosmic history; it was generating an exceptionally large amount of stars in the calm, dark cosmos.

Located within the borders of the constellation Pegasus, Stephan's Quintet consists of a visual grouping of five galaxies, four of which form an actual compact group of galaxies; one additional galaxy appears in images of the group but is much closer than the others. Refinements in observations of the quintet are revealing more about its members. A comparison of images compiled by using a suite of specialized filters with Subaru's Prime Focus Camera have shown different types of star-formation activity between the closer galaxy NGC7320 and the more distant galaxies in Stephan's Quintet. They show the quintet in 3-D.

The researchers concluded that another asteroid about 20-50 meters in size impacted Scheila from behind on December 3, 2010 and accounted for its unusual brightness and form. Wed, 19 Oct 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111011 An international team of astronomers has discovered over two-dozen new free-floating brown dwarfs that reside in two young star clusters. One brown dwarf is a lightweight youngster only about six times heftier than Jupiter. Tue, 11 Oct 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#111005 A research team of astronomers, mainly from Ehime University and Kyoto University in Japan, has successfully detected a carbon emission line (CIVλ1549) in the most distant radio galaxy known so far in the early universe. Using the Faint Object Camera and Spectrograph (FOCAS) on the Subaru Telescope, the team observed the radio galaxy TN J0924-2201, which is 12.5 billion light years away, and was able to measure its chemical composition for the first time.

Mon, 3 Oct 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#110805 A research team of astronomers from the University of Tokyo and the National Astronomical Society of Japan (NAOJ) has identified the location of red star-forming galaxies around a galaxy cluster situated four billion light years away from Earth. A panoramic observation with the Subaru Telescope yielded the result. Scientists surmise that such "red-burning galaxies" are in a transitional phase from a young generation of galaxies to an older one; they may demonstrate the dramatic evolution of galaxies in the environment surrounding the cluster. Fri, 5 Aug 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#110706 A research team at NAOJ has begun scientific observations with Subaru Telescope's Laser Guide Star Adaptive Optics (LGSAO) system. The LGSAO uses a powerful laser to illuminate the sodium layer of the atmosphere and create an artificial guide star that shines in the upper atmosphere. Wed, 6 Jul 2011 09:00:00 -1000 Science Results http://www.naoj.org/Pressrelease/index_2011.html#110603 A team of researchers from four Japanese universities (Kobe, Saitama, Osaka, and Tokyo) has been able to delineate the intricate structure of the circumbinary disk that surrounds a young binary star system from the observation with the Subaru Telescope and the Hubble Space Telescope. By using different wavelengths to examine the system's internal structure, they succeeded in demonstrating a distinct color difference between its northern and southern portions.
