Low-redshift absorption in the Seyfert galaxy PG 1211+143 -- a distant inflow maintaining off-plane accretion or the gravitational redshift of matter orbiting the SMBH?
Ken Pounds, Kim Page
The detection of a high velocity (~ 0.3c) inflow of highly ionized matter during an extended XMM-Newton observation of the luminous Seyfert galaxy PG 1211+143 in 2014 provided the…
Observing the launch of an Eddington wind in the luminous Seyfert galaxy PG1211+143
Ken Pounds, Kim Page
The luminous narrow line Seyfert galaxy PG1211+143 was the first non-BAL AGN to reveal a powerful ionized wind, based on early observations with ESA's XMM-Newton X-ray Observatory.…
Are ultrafast inflows in AGN truly rare -- or just much harder to see?
Ken Pounds
Short-term variability and multiple velocity components in the powerful highly ionized wind of the archetypal UFO PG 1211+143 are indicative of inner disc instabilities or short-li…
Possible evidence for shock-cooling in the accretion flow of the luminous Seyfert galaxy PG1211+143
Ken Pounds, Andrew Lobban
Short-term variability and multiple velocity components in the powerful highly ionized wind of the archetypal UFO PG1211+143 are indicative of inner disc instabilities or short-liv…
An ultra-fast inflow in the luminous Seyfert PG1211+143
Ken Pounds, Chris Nixon, Andrew Lobban +1
Blueshifted absorption lines in the X-ray spectra of AGN show that ultra-fast outflows with typical velocities are a common feature of these luminous objects. Such po…
X-ray time lags in PG 1211+143
Andrew Lobban, Simon Vaughan, Ken Pounds +1
We investigate the X-ray time lags of a recent ~630ks XMM-Newton observation of PG 1211+143. We find well-correlated variations across the XMM-Newton EPIC bandpass, with the first…
