A deep X-ray view of the bare AGN Ark 120. II. Evidence for Fe K emission transients
E. Nardini, D. Porquet, J. N. Reeves +3
We report on the results from a large observational campaign on the bare Seyfert galaxy Ark 120, jointly carried out in 2014 with XMM-Newton, Chandra, and NuSTAR. The fortunate lin…
Testing relativistic reflection and resolving outflows in PG 1211+143 with XMM-Newton and NuSTAR
Andrew Lobban, Ken Pounds, Simon Vaughan +1
We analyze the broad-band X-ray spectrum (0.3-50 keV) of the luminous Seyfert 1 / quasar PG 1211+143 - the archetypal source for high-velocity X-ray outflows - using near-simultane…
Exploring accretion disc physics and black hole growth with regular monitoring of ultrafast AGN winds
Ken Pounds, Andrew Lobban, Chris Nixon
15 years of XMM-Newton observations have established that ultra-fast, highly ionized winds are common in radio-quiet AGN. A simple theory of Eddington-limited accretion correctly p…
A deep X-ray view of the bare AGN Ark 120. I. Revealing the Soft X-ray Line Emission
James Reeves, Delphine Porquet, Valentina Braito +3
The Seyfert 1 galaxy, Ark 120, is a prototype example of the so-called class of bare nucleus AGN, whereby there is no known evidence for the presence of ionized gas along the direc…
Detection of a second high velocity component in the highly ionized wind from PG 1211+143
Ken Pounds, Andrew Lobban, James Reeves +1
An extended XMM-Newton observation of the luminous narrow line Seyfert galaxy PG 1211+143 in 2014 has revealed a more complex highly ionized, high velocity outflow. The detection o…
