XMM-Newton observations of the Lockman Hole IV: spectra of the brightest AGN
S. Mateos, X. Barcons, F. J. Carrera +5
This paper presents the results of a detailed X-ray spectral analysis of a sample of 123 X-ray sources (46 being type-1 AGN and 28 type-2 AGN) detected with XMM-Newton in the Lockm…
Probing the precession of the inner accretion disk in Cygnus X-1
Diego F. Torres, Gustavo E. Romero, Xavier Barcons +1
We show that changes in the orientation of the inner accretion disk of Cygnus X-1 affect the shape of the broad Fe K emission line emitted from this object, in such a way that e…
Tentative detection of warm intervening gas towards PKS 0548-322 with XMM-Newton
X. Barcons, F. B. S. Paerels, F. J. Carrera +2
We present the results of a long (~93 ksec) XMM-Newton observation of the bright BL-Lac object PKS 0548-322 (z=0.069). Our Reflection Grating Spectrometer (RGS) spectrum shows a si…
