The XMM - Newton view of NGC 6251
We report on the nuclear X-ray properties of the radio galaxy NGC 6251 observed with XMM-Newton. NGC 6251 is a well-known radio galaxy with intermediate FRI/II radio properties. It is optically classified as a Seyfert 2 and hosts a supermassive black hole with mass ∼ 6 × 10 8 M⊙. The 0.4–10 keV EPIC pn continuum is best fitted by two thermal components (kT ∼ 0.5 and 1.4 keV, respectively), plus...
متن کاملArakelian 564: An XMM-Newton view
We report on two XMM-Newton observations of the bright narrow-line Seyfert 1 galaxy Ark 564 taken one year apart (2000 June and 2001 June). The 0.6–10 keV continuum is well described by a soft blackbody component (kT ≈ 140–150 eV) plus a steep power law (Γ ≈ 2.50–2.55). No significant spectral changes are observed between the two observations, although the X-ray flux in the second observation i...
متن کاملThe XMM–Newton view of Mrk 3 and IXO 30
We present the analysis of the XMM-Newton EPIC pn spectrum of the Seyfert 2 galaxy, Mrk 3. We confirm that the source is dominated by a pure Compton reflection component and an iron Kα line, both produced as reflection from a Compton-thick torus, likely responsible also for the large column density (1.36 −0.04 × 10 24 cm) which is pierced by the primary powerlaw only at high energies. A low inc...
متن کاملDisentangling the Complex Broadband X-ray Spectrum of IRAS13197-1627 with NuSTAR, XMM-Newton and Suzaku
We present results from a coordinated XMM-Newton+NuSTAR observation of the type 1.8 Seyfert galaxy IRAS 13197-1627. This is a highly complex source, with strong contributions from relativistic reflection from the inner accretion disk, neutral absorption and further reprocessing by more distant material, and ionised absorption from an outflow. We undertake a detailed spectral analysis combining ...
متن کاملTHE RHYTHM OF FAIRALL 9. I. OBSERVING THE SPECTRAL VARIABILITY WITH XMM-NEWTON AND NuSTAR
We present a multi-epoch X-ray spectral analysis of the Seyfert1 galaxy Fairall9. Our analysis shows that Fairall9 displays unique spectral variability in that its ratio residuals to a simple absorbed power law in the 0.5–10 keV band remain constant with time in spite of large variations in flux. This behavior implies an unchanging source geometry and the same emission processes continuously...
