The nature of the broadband X-ray variability in the dwarf Seyfert galaxy NGC 4395
E. S. Kammoun, E. Nardini, A. Zoghbi +14
We present a flux-resolved X-ray analysis of the dwarf Seyfert 1.8 galaxy NGC 4395, based on three archival and one archival observations. The source is known…
A NICER Look at Strong X-ray Obscuration in the Seyfert-2 Galaxy NGC 4388
J. M. Miller, E. Kammoun, R. M. Ludlam +4
We present an analysis of the time-averaged spectrum of the Seyfert-2 active galaxy NGC 4388, obtained by NICER. The intrinsic strength of the reflection spectrum in NGC 4388, the…
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…
Steep X-ray reflection emissivity profiles in AGN as the result of radially-structured disc ionisation
E. S. Kammoun, V. Domcek, J. Svoboda +2
X-ray observations suggest high compactness of coronae in active galactic nuclei as well as in X-ray binaries. The compactness of the source implies a strong radial dependence in t…
