Discovery of multiple Lorentzian components in the X-ray timing properties of the Narrow Line Seyfert 1 Ark 564
I. M. McHardy, P. Arevalo, P. Uttley +4
We present a power spectral analysis of a 100 ksec XMM-Newton observation of the narrow line Seyfert 1 galaxy Ark~564. When combined with earlier RXTE and ASCA observations, these…

Timing evidence in determining the accretion state of the Seyfert galaxy NGC 3783
D. P. Summons, P. Arevalo, I. M. McHardy +2
Previous observations with the Rossi X-ray Timing Explorer (RXTE) have suggested that the power spectral density (PSD) of NGC 3783 flattens to a slope near zero at low frequencies,…
