Tracing a Disk Wind in NGC 3516
T. J. Turner, J. N. Reeves, S. B. Kraemer +1
X-ray spectra of AGN often contain signatures indicative of absorption in multiple layers of gas whose ionization-state and covering fraction may vary with time. It has been unclea…
An absorption origin for the X-ray spectral variability of MCG-6-30-15
L. Miller, T. J. Turner, J. N. Reeves
The Seyfert I galaxy MCG-6-30-15 shows one of the best examples of a broad "red wing" of emission in its X-ray spectrum at energies 2 < E < 6.4 keV, commonly interpreted as being c…
The Variable X-ray Spectrum of Markarian 766 - II. Time-Resolved Spectroscopy
T. J. Turner, L. Miller, J. N. Reeves +1
CONTEXT: The variable X-ray spectra of AGN systematically show steep power-law high states and hard-spectrum low states. The hard low state has previously been found to be a compon…
The variable X-ray spectrum of Markarian 766 - I. Principal components analysis
L. Miller, T. J. Turner, J. N. Reeves +3
Aims: We analyse a long XMM-Newton spectrum of the narrow-line Seyfert 1 galaxy Mrk 766, using the marked spectral variability on timescales >20ks to separate components in the X-r…
A Massive X-Ray Outflow from the Quasar PDS 456
James Reeves, Paul O'Brien, Martin Ward
We report on XMM-Newton spectroscopic observations of the luminous, radio-quiet quasar PDS 456. The hard X-ray spectrum of PDS 456 shows a deep absorption trough (constituting 50%…
