Strong variability of the coronal line region in NGC 5548
Hermine Landt, Martin J. Ward, Katrien C. Steenbrugge +1
We present the second extensive study of the coronal line variability in an active galaxy. Our data set for the well-studied Seyfert galaxy NGC 5548 consists of five epochs of quas…
Anatomy of the AGN in NGC 5548: V. A clear view of the X-ray narrow emission lines
M. Whewell, G. Branduardi-Raymont, J. S. Kaastra +15
Context. Our consortium performed an extensive multi-wavelength campaign of the nearby Seyfert 1 galaxy NGC 5548 in 2013-14. The source appeared unusually heavily absorbed in the s…
Anatomy of the AGN in NGC 5548 IV. The short-term variability of the outflows
L. Di Gesu, E. Costantini, J. Ebrero +16
During an extensive multiwavelength campaign that we performed in 2013-14 the prototypical Seyfert 1 galaxy NGC 5548 has been found in an unusual condition of heavy and persistent…
The broad-line region and dust torus size of the Seyfert 1 galaxy PGC50427
F. Pozo Nuñez, M. Ramolla, C. Westhues +10
We present the results of a three years monitoring campaigns of the type-1 active galactic nucleus (AGN) PGC50427. Through the use of Photometric Reverberation Mapping…
Anatomy of the AGN in NGC 5548: III. The high-energy view with NuSTAR and INTEGRAL
F. Ursini, R. Boissay, P. -O. Petrucci +15
We describe the analysis of the seven broad-band X-ray continuum observations of the archetypal Seyfert 1 galaxy NGC 5548 that were obtained with XMM-Newton or Chandra, simultaneou…
Variability of the coronal line region in NGC 4151
Hermine Landt, Martin J. Ward, Katrien C. Steenbrugge +1
We present the first extensive study of the coronal line variability in an active galaxy. Our data set for the nearby source NGC 4151 consists of six epochs of quasi-simultaneous o…
