Broad iron L-line and X-ray reverberation in 1H0707-495
A detailed analysis of a long XMM-Newton observation of the Narrow Line Seyfert 1 galaxy 1H0707-495 is presented, including spectral fitting, spectral variability and timing studies. The two main features in the spectrum are the drop at ∼ 7 keVand a complex excess below 1 keV . These are well described by two broad, K and L, iron lines. Alternative models based on absorption, although they may ...
متن کاملAn accretion disc origin for the ‘X-ray broad line region’ in 1H0707-495
We use a 380 ks XMM-Newton high-resolution RGS spectrum to look for narrow spectral features from the nuclear environment of 1H0707-495. We do not find any evidence of a line-of-sight ionized wind (warm absorber). We do, however, detect broad emission lines, of width ∼5000 km s, consistent with O VIII Lyα, N VII Lyα, C VI Lyα and a Fe XIX/Fe XX/Ne IX Heα blend. Intriguingly, these lines have bo...
متن کاملX-ray iron line reverberation from black hole accretion disks
The relativistically broad X-ray iron line seen in many AGN spectra is thought to originate from the central regions of the putative black hole accretion disk. Both the line profile and strength will vary in response to rapid variability of the primary X-ray continuum source. The temporal response of the line contains information on the accretion disk structure, the X-ray source geometry, and t...
متن کاملIron Line Reverberation Mapping with Constellation-x
The broad X-ray iron line seen in the spectra of many AGN is thought to originate from the inner regions of the putative black hole accretion disk, and hence provides a rare probe of that central region. In principle, future high throughput X-ray spectrometers should be able to examine the temporal response of this fluorescent line to flares in the X-ray continuum source (which energizes this e...
متن کاملRelativistic iron K X-ray reverberation in NGC 4151
Recent X-ray observations have enabled the study of reverberation delays in active galactic nuclei (AGN) for the first time. All the detections so far are in sources with a strong soft excess, and the measured delay is between the hard (1–3 keV) direct continuum and the soft excess (0.5–1 keV), interpreted as the reflection continuum smeared by relativistic effects. There is however an inherent...
