The nature of the soft-excess and spectral variability in the Seyfert 1 galaxy Zw 229.015
S. Tripathi, S. G. H. Waddell, L. C. Gallo +2
We have carried out a systematic analysis of the nearby (z=0.0279) active galaxy Zw 229.015 using multi-epoch, multi-instrument and deep pointed observations with XMM-Newton, Suzak…
The 1.5 Ms Observing Campaign on IRAS 13224-3809: X-ray Spectral Analysis I
J. Jiang, M. L. Parker, A. C. Fabian +16
We present a detailed spectral analysis of the recent 1.5\,Ms XMM-Newton observing campaign on the narrow line Seyfert 1 galaxy IRAS~132243809, taken simultaneously with 500\,ks…
Is there a UV/X-ray connection in IRAS 13224-3809?
D. J. K. Buisson, A. M. Lohfink, W. N. Alston +16
We present results from the optical, ultraviolet and X-ray monitoring of the NLS1 galaxy IRAS 13224-3809 taken with Swift and XMM-Newton during 2016. IRAS 13224-3809 is the most va…
Accretion disk reverberation with Hubble Space Telescope observations of NGC 4593: evidence for diffuse continuum lags
Edward M. Cackett, Chia-Ying Chiang, Ian McHardy +4
The Seyfert 1 galaxy NGC 4593 was monitored spectroscopically with the Hubble Space Telescope as part of a reverberation mapping campaign that also included Swift, Kepler and groun…
X-ray Lags in PDS 456 Revealed by Suzaku Observations
Chia-Ying Chiang, E. M. Cackett, A. Zoghbi +5
X-ray reverberation lags from the vicinity of supermassive black holes have been detected in almost 30 AGN. The soft lag, which is the time delay between the hard and soft X-ray li…
The response of relativistic outflowing gas to the inner accretion disk of a black hole
Michael L. Parker, Ciro Pinto, Andrew C. Fabian +21
Active galactic nucleus (AGN) feedback is the process by which supermassive black holes in the centres of galaxies may moderate the growth of their hosts. Gas outflows from superma…
