The X-ray Disk/Wind Degeneracy in AGN
M. L. Parker, G. A. Matzeu, J. H. Matthews +4
Relativistic Fe K emission lines from accretion disks and from disk winds encode key information about black holes, and their accretion and feedback mechanisms. We show that these…
The nature of the extreme X-ray variability in the NLS1 1H 0707-495
M. L. Parker, W. N. Alston, L. Härer +11
We examine archival XMM-Newton data on the extremely variable narrow-line Seyfert 1 (NLS1) active galactic nucleus (AGN) 1H 0707-495. We construct fractional excess variance (Fvar)…
The X-ray emission of the Seyfert 2 galaxy MCG-01-24-12
R. Middei, G. A. Matzeu, S. Bianchi +7
We present a detailed X-ray spectral analysis of the nearby Seyfert 2 galaxy MCG-01-24-12 based on a multi-epoch data set. Data have been taken with different X-ray satellites, nam…
Modelling X-ray RMS spectra II: the ultra-fast outflow of PDS 456
L. Härer, M. L. Parker, A. Joyce +6
We present an improved model for excess variance spectra describing ultra-fast outflows and successfully apply it to the luminous (L ~ 10^47 erg/s) low-redshift (z = 0.184) quasar…
The flaring X-ray corona in the quasar PDS 456
James Reeves, Valentina Braito, Delphine Porquet +3
New Swift monitoring observations of the variable, radio-quiet quasar, PDS 456, are presented. A bright X-ray flare was captured in September 2018, the flux increasing by a factor…
The stratified disk wind of MCG-03-58-007
V. Braito, J. N. Reeves, P. Severgnini +6
Past Suzaku, XMM and NuSTAR observations of the nearby (z=0.0323) bright Seyfert 2 galaxy MCG-03-58-007 revealed the presence of two deep and blue-shifted Fe K-shell absorption lin…
