The X-ray variability and the near-IR to X-ray spectral energy distribution of four low luminosity Seyfert 1 galaxies
I. E. Papadakis, Z. Ioannou, W. Brinkmann +1
We present the results from a study of the X-ray variability and the near-IR to X-ray spectral energy distribution of four low-luminosity, Seyfert 1 galaxies. We compared their var…
The soft X-ray properties of AGN from the CJF sample; A correlation analysis between soft X-ray and VLBI properties
S. Britzen, W. Brinkmann, R. M. Campbell +4
Context: We present the soft X-ray properties obtained in the ROSAT All-Sky survey and from pointed PSPC observations for the AGN in the complete flux-density limited Caltech-Jodre…
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…
Spectral variability analysis of an XMM-Newton observation of Ark 564
W. Brinkmann, I. E. Papadakis, C. Raeth
We present a spectral variability analysis of the X-ray emission of the Narrow Line Seyfert 1 galaxy Ark 564 using the data from a ~100 ks XMM-Newton observation. Taking advantage…
Long-Term X-Ray spectral variability of the radio-loud NLS1 galaxy PKS 0558-504
M. Gliozzi, I. E. Papadakis, W. Brinkmann
We present X-ray observations of the Narrow-Line Seyfert 1 galaxy PKS 0558-504 obtained with RXTE during a 1-year monitoring campaign. This source, which is one of the very few rad…
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…
