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…
A Full Characterisation of the Supermassive Black Hole in IRAS 09149-6206
D. J. Walton, W. N. Alston, P. Kosec +11
We present new broadband X-ray observations of the type-I Seyfert galaxy IRAS 09149-6206, taken in 2018 with -, and . The source is highly complex, sho…
Detection of a possible multiphase ultra-fast outflow in IRAS 13349+2438 with NuSTAR and XMM-Newton
M. L. Parker, G. A. Matzeu, W. N. Alston +6
We present joint NuSTAR and XMM-Newton observations of the bright, variable quasar IRAS 13349+2438. This combined dataset shows two clear iron absorption lines at 8 and 9 keV, whic…
The first broadband X-ray view of the narrow line Seyfert 1 Ton S180
G. A. Matzeu, E. Nardini, M. L. Parker +15
We present joint \textit{XMM-Newton} and \textit{NuSTAR} observations of the `bare' narrow line Seyfert 1 Ton S180 (), carried out in 2016 and providing the first hard X-r…
Characterising continuum variability in the radio-loud narrow-line Seyfert 1 galaxy IRAS 17020+4544
A. G. Gonzalez, L. C. Gallo, P. Kosec +4
We present results of temporal and spectral analyses on four XMM-Newton EPIC pn observations of IRAS 17020+4544, a narrow-line Seyfert 1 galaxy with evidence of a radio jet. Analys…
Blueshifted absorption lines from X-ray reflection in IRAS 13224-3809
A. C. Fabian, C. S. Reynolds, J. Jiang +17
We explore a disc origin for the highly-blueshifted, variable absorption lines seen in the X-ray spectrum of the Narrow Line Seyfert 1 galaxy IRAS13224-3809. The blueshift correspo…
