(PhysOrg.com) -- The nucleus of an active galaxy, an AGN, contains a massive black hole that is vigorously accreting material. In the process it typically ejects jets of particles and radiates brightly at many wavelengths, in particular at X-ray wavelengths. http://www.physorg.com/news177337799.html Space & Earth Fri, 13 Nov 2009 12:30:51 EST news177337799 An international team of astronomers has used the world's biggest radio telescope to look deep into the brightest galaxies that NASA's Fermi Gamma-ray Space Telescope can see. The study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. http://www.physorg.com/news159639919.html Space & Earth Wed, 22 Apr 2009 17:25:56 EST news159639919 (PhysOrg.com) -- An ongoing X-ray survey undertaken by NASA's Swift spacecraft is revealing differences between nearby active galaxies and those located about halfway across the universe. Understanding these differences will help clarify the relationship between a galaxy and its central black hole. http://www.physorg.com/news150482218.html Space & Earth Tue, 06 Jan 2009 16:36:58 EST news150482218
