A hard look at thermal reverberation and optical/UV lags in NGC 5548
E. S. Kammoun, I. E. Papadakis, M. Dovciak
The UV/optical variations in many AGN are very well correlated, showing delays which increase with increasing wavelength. It is thought that this is due to thermal reprocessing of…
A hard look at NGC 5347: revealing a nearby Compton-thick AGN
E. S. Kammoun, J. M. Miller, A. Zoghbi +11
Current measurements show that the observed fraction of Compton-thick (CT) AGN is smaller than the expected values needed to explain the cosmic X-ray background. Prior fits to the…
Bulk Comptonization: new hints from the luminous blazar 4C+25.05
E. S. Kammoun, E. Nardini, G. Risaliti +3
Blazars are often characterized by a spectral break at soft X-rays, whose origin is still debated. While most sources show a flattening, some exhibit a blackbody-like soft excess w…
The nature of X-ray spectral variability in MCG-6-30-15
E. S. Kammoun, I. E. Papadakis
The flux-flux plot (FFP) method can provide model-independent clues regarding the X-ray variability of active galactic nuclei. To use it properly, the bin size of the light curves…
