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…
Searching for Ultra-fast Outflows in AGN using Variability Spectra
Z. Igo, M. L. Parker, G. A. Matzeu +8
We present a qualitative search for ultra-fast outflows (UFOs) in excess variance spectra of radio-quiet active galactic nuclei (AGN). We analyse 42 sources from the Tombesi et al.…
Evidence for a clumpy disc-wind in the star forming Seyfert\,2 galaxy MCG--03--58--007
G. A. Matzeu, V. Braito, J. N. Reeves +9
We report the results of a detailed analysis of a deep simultaneous \textit{XMM-Newton & NuSTAR} observation of the nearby () and bright ($L_{\rm bol}\sim3\…
A high velocity component to the complex absorption in IRAS 13349+2438
M. L. Parker, G. A. Matzeu, M. Guainazzi +4
We present an analysis of XMM-Newton spectra of the low-redshift quasar IRAS 13349+2438. The RGS spectrum shows a large number of absorption lines from two zones of warm absorption…
Finding AGN in Deep X-ray Flux States with Swift
Dirk Grupe, S. Komossa, Mason Bush +7
We report on our ongoing project of finding Active Galactic Nuclei (AGN) that go into deep X-ray flux states detected by Swift. Swift is performing an extensive study on the flux a…
