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 IRAS 13224−3809. The blueshift corresponds to a velocity of ∼0.25c. Such features in other active galactic nuclei are often interpreted as ultrafast outflows. The velocity is of course present in the orbital motions of the inner disc. The absorption lines in IRAS 13224−3809 are best seen when the flux is low and the reflection component of the disc is… Expand

Detection of a variable ultrafast outflow in the narrow-line Seyfert 1 galaxy PG 1448+273
Relativistically blueshifted absorption features of highly ionised ions, the so-called ultra-fast outflows (UFOs), have been detected in the X-ray spectra of a number of accreting supermassive blackExpand
Detection of a possible multiphase ultra-fast outflow in IRAS 13349+2438 with NuSTAR and XMM–Newton
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, which are most likelyExpand
The awakening beast in the Seyfert 1 Galaxy KUG 1141+371 – I
KUG 1141+371 is a Seyfert 1 galaxy that shows a simultaneous flux increase in the optical and UV bands in the past decade. For instance, the latest Swift observation in 2019 shows that the UVW2Expand
Maximum observable blueshift from circular equatorial Kerr orbiters
The region of spacetime near the event horizon of a black hole can be viewed as a deep potential well at large gravitational redshift relative to distant observers. However, matter orbiting in thisExpand


The origin of blueshifted absorption features in the X-ray spectrum of PG 1211+143: outflow or disc.
In some radio-quiet active galaxies (AGN), high-energy absorption features in the x-ray spectra have been interpreted as Ultrafast Outflows (UFOs) -- highly ionised material (e.g. Fe XXV and Fe XXVI)Expand
Resolved atomic lines reveal outflows in two ultraluminous X-ray sources
It is concluded that the compact object in each source is surrounded by powerful winds with an outflow velocity of about 0.2 times that of light, as predicted by models of accreting supermassive black holes and hyper-accreting stellar-mass black holes. Expand
The 1.5 Ms observing campaign on IRAS 13224-3809 - I. X-ray spectral analysis
We present a detailed spectral analysis of the recent 1.5 Ms XMM–Newton observing campaign on the narrow-line Seyfert 1 galaxy IRAS 13224−3809, taken simultaneously with 500 ks of NuSTAR data. TheExpand
It is proposed that the iron K-shell absorption in PDS 456 is associated with a thick, possibly clumpy outflow, covering about 20% of 4π steradian solid angle, which is likely launched from the inner accretion disk, within 15-100 gravitational radii of the black hole. Expand
How the effects of resonant absorption on black hole reflection spectra can mimic high-velocity outflows
Narrow absorption lines seen in the 2–10 keV spectra of active galaxies and Galactic black holes are normally attributed to iron in high-velocity outflows or inflows. We consider the possibility thatExpand
X-Ray Iron Line Reverberation from Black Hole Accretion Disks
The relativistically broad X-ray iron line seen in many active galactic nucleus (AGN) spectra is thought to originate from the central regions of the putative black hole accretion disk. Both the lineExpand

Unification of X-ray winds in Seyfert galaxies: from ultra-fast outflows to warm absorbers
The existence of ionized X-ray absorbing layers of gas along the line of sight to the nuclei of Seyfert galaxies is a well established observational fact. This material is systematically outflowingExpand

Context. Blue-shifted Fe K absorption lines have been detected in recent years between 7 and 10 keV in the X-ray spectra of several radio-quiet AGNs. The derived blue-shifted velocities of the linesExpand
