A team of astronomers from France and South Africa announced the first catalog of a new type of gamma-ray source, a dozen clouds of "relic" radiation from dead stars that reveal information about the energetic past of these celestial objects. These findings were presented on Feb. 5, 2007 at the first Gamma Ray Large-Area Space Telescope (GLAST) scientific Symposium meeting in Palo Alto, Calif., by Dr. Arache Djannati-Ataï, an astrophysicist from the Astroparticle...

New Haven, Conn. -- An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths; a complementary study of jet X-ray emission led by astronomers at the University of Southampton, reaches the same conclusion. Both studies involve the jet of the quasar 3C273,...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear.
