XMM-Newton observation of the NLS1 Galaxy Ark 564: I. Spectral analysis of the time-average spectrum

I. E. Papadakis, W. Brinkmann, M. J. Page +2

We use the data from a recent, 100 ksec XMM-Newton observation of the Narrow Line Seyfert 1 galaxy Ark 564 to obtain its time average, X-ray spectrum. The 3-11 keV spectrum is well…

Spectral-timing evidence for a Very High State in the Narrow Line Seyfert 1 Ark 564

P. Arevalo, I. E. Papadakis, P. Uttley +2

We use a 100 ks long XMM-Newton observation of the Narrow-Line Seyfert 1 galaxy Ark 564 and combine it with the month-long monitoring of the same source produced by ASCA, to calcul…
