Understanding Giant Radio Galaxy J1420-0545: Large-Scale Morphology, Environment, and Energetics
Understanding Giant Radio Galaxy J1420-0545: Large-Scale Morphology, Environment, and Energetics
2011/10/18
In this paper we consider the possibility that the structure of the largest radio galaxy J1420-0545 is formed by a restarted rather than a primary jet activity. This hypothesis is motivated by the unu...
Chemical properties in the most distant radio galaxy
galaxies: active – galaxies: nuclei – quasars: emission lines – quasars: general
2011/10/21
We present a deep optical spectrum of TN J0924-2201, the most distant radio galaxy at z = 5.19, obtained with FOCAS on the Subaru Telescope. We successfully detect, for the first time, the CIV1549 emi...
The inverse-Compton ghost HDF 130 and the giant radio galaxy 6C 0905+3955: matching an analytic model for double radio source evolution
galaxies: individual: RGJ123617/HDF130, 6C0905+3955 – galaxies: evolution – galaxies: jets – radio continuum: galaxies – X-rays: galaxies.
2011/9/28
We present new GMRT observations of HDF 130, an inverse-Compton (IC) ghost of a giant radio source that is no longer being powered by jets. We compare the properties of HDF 130 with the new and import...
Chandra high resolution spectroscopy of the circumnuclear matter in the Broad Line Radio Galaxy 3C445
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/29
We present evidence for X-ray line emitting and absorbing gas in the nucleus of the Broad-Line Radio Galaxy (BLRG), 3C 445. A 200ks Chandra LETG observation of 3C 445 reveals the presence of several h...
The Spitzer High Redshift Radio Galaxy Survey
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/27
We present results from a comprehensive imaging survey of 70 radio galaxies at redshifts 1 all three cameras onboard the Spitzer Space Telescope. The resulting spectral energy distribution...
