The XMM - Newton view of the broad - line radio galaxy 3 C 120
We present the results of a 127 ks XMM-Newton observation of the broad-line radio galaxy 3C 120 performed simultaneously with RXTE. The data have yielded the highest quality 0.6– 10 keV spectrum of a radio-loud active galaxy ever produced. The time-averaged spectrum is Seyfert-like, with a reflection amplitude R ∼ 0.5, and a neutral Fe Kα line with equivalent width ∼ 53 eV. The line is slightly...
متن کاملNustar Reveals the Comptonizing Corona of the Broad-line Radio Galaxy
Broad-line radio galaxies (BLRGs) are active galactic nuclei that produce powerful, large-scale radio jets, but appear as Seyfert 1 galaxies in their optical spectra. In the X-ray band, BLRGs also appear like Seyfert galaxies, but with flatter spectra and weaker reflection features. One explanation for these properties is that the X-ray continuum is diluted by emission from the jet. Here, we pr...
متن کاملLoud Quasar Lobe Dominated Radio Loud Quasar Radio Galaxy Broad
In this second paper, in a series of two, we determine the properties of the stellar torus that we showed in the first paper to result as a product of two merging black holes. If the surrounding stellar cluster is as massive as the binary black hole, the torque acting on the stars ejects a fraction which extracts the binary’s angular momentum. After the black holes coalesced on scales of ∼ 10 y...
متن کاملDiscovery of an Obscured Broad-Line Region in the High-Redshift Radio Galaxy MRC 2025-218.
This Letter presents infrared spectra taken with the newly commissioned near-infrared spectrometer (NIRSPEC) on the Keck II telescope of the high-redshift radio galaxy MRC 2025-218 (z=2.63). These observations represent the deepest infrared spectra of a radio galaxy to date and have allowed for the detection of Hbeta, [O iii] lambdalambda4959, 5007, [O i] lambda6300, Halpha, [N ii] lambdalambda...
متن کاملX - ray spectroscopy of the broad line radio galaxy 3 C 111
We present an ASCA observation of the broad line radio galaxy 3C 111. The Xray spectrum is well described by a model consisting of a photoelectrically-absorbed power-law form. The inferred absorbing column density is significantly greater than expected on the basis of 21-cm measurements of Galactic H i. Whilst this may be due intrinsic absorption from a circumnuclear torus or highly warped accr...
