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 کاملThe X-ray Properties of the Nearby Star-forming Galaxy Ic 342: the Xmm-newton View
We present results on the X-ray properties of IC 342 using a 10 ks XMM-Newton observation. Thirty-five sources are detected coincident with the disk of IC 342 (more than tripling the number known), of which ≈ 31 are likely to be intrinsic to IC 342. This point-source population exhibits a diverse range of spectral properties and has an X-ray luminosity function slope and infrared luminosity com...
متن کاملAn XMM–Newton view of the young open cluster NGC 6231 – II. The OB star population
In this second paper of the series, we pursue the analysis of the 180-ks XMM–Newton campaign towards the young open cluster NGC 6231 and we focus on its rich OB star population. We present a literature-based census of the OB stars in the field of view with more than one hundred objects, among which 30 per cent can be associated with an X-ray source. All the O-type stars are detected in the X-ra...
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...
