Modelling X-ray RMS spectra II: the ultra-fast outflow of PDS 456
L. Härer, M. L. Parker, A. Joyce +6
We present an improved model for excess variance spectra describing ultra-fast outflows and successfully apply it to the luminous (L ~ 10^47 erg/s) low-redshift (z = 0.184) quasar…

Detection of a variable ultra-fast outflow in the Narrow Line Seyfert 1 galaxy PG 1448+273
P. Kosec, A. Zoghbi, D. J. Walton +4
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…

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.…
