Anatomy of the AGN in NGC 5548 VIII. XMM-Newton's EPIC detailed view of an unexpected variable multilayer absorber
M. Cappi, B. De Marco, G. Ponti +21
In 2013 we conducted a large multi-wavelength campaign on the archetypical Seyfert 1 galaxy NGC 5548. Unexpectedly, this usually unobscured source appeared strongly absorbed in the…
Multiwavelength studies of the Seyfert 1 galaxy NGC7469. I - Far UV observations with FUSE
G. A. Kriss, A. Blustin, G. Branduardi-Raymont +3
We obtained far-ultraviolet spectra of the Seyfert 1 galaxy NGC 7469 using the FUSE on 1999 December 6. Our spectra cover the wavelength range 990-1187 A with a resolution of 0.05…
XMM - Newton observations of Markarian 421
W. Brinkmann, S. Sembay, R. G. Griffiths +6
The BL Lac object Mrk 421 was observed on May 25, 2000 during the XMM - Newton CAL/PV phase. The high throughput of the X-ray telescopes and the spectral capabilities of the instru…
Soft X-ray emission lines from a relativistic accretion disk in MCG -6-30-15 and Mrk 766
G. Branduardi-Raymont, M. Sako, S. M. Kahn +3
XMM-Newton Reflection Grating Spectrometer (RGS) spectra of the Narrow Line Seyfert 1 galaxies MCG -6-30-15 and Mrk 766 are physically and spectroscopically inconsistent with stand…
