Long-term monitoring of Ark 120 with Swift
M. Gliozzi, I. E. Papadakis, D. Grupe +2
We report the results of a six-month Swift monitoring campaign of Ark120, a prototypical bare Seyfert1 galaxy. The lack of intrinsic absorption combined with the nearly contemporan…
Long-term monitoring of PKS0558-504 with Swift: the disc-corona link
M. Gliozzi, I. E. Papadakis, D. Grupe +2
PKS 0558-504 is a highly variable, X-ray bright, radio-loud, Narrow-Line Seyfert 1 galaxy with super-Eddington accretion rate and extended jets that do not dominate the emission be…
Revisiting algorithms for generating surrogate time series
C. Raeth, M. Gliozzi, I. E. Papadakis +1
The method of surrogates is one of the key concepts of nonlinear data analysis. Here, we demonstrate that commonly used algorithms for generating surrogates often fail to generate…
A panchromatic view of PKS 0558-504: an ideal laboratory to study the disk-jet link
M. Gliozzi, I. E. Papadakis, D. Grupe +3
PKS 0558-504 is the brightest radio-loud Narrow-Line Seyfert 1 galaxy at X-ray energies. Here we present results from the radio, optical, UV, and X-ray bands obtained with Swift, X…
XMM-Newton long-look observation of the narrow line Seyfert 1 galaxy PKS0558-504; I: Spectral analysis
I. E. Papadakis, W. Brinkmann, M. Gliozzi +3
We present results from the spectral analysis of a long XMM-Newton observation of the radio-loud NLS1 galaxy PKS0558-504. The source is highly variable, on all sampled time scales.…
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…
