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…
RoboPol: The optical polarization of gamma-ray--loud and gamma-ray--quiet blazars
E. Angelakis, T. Hovatta, D. Blinov +25
We present average R-band optopolarimetric data, as well as variability parameters, from the first and second RoboPol observing season. We investigate whether gamma- ray--loud and…
Theoretical modelling of the AGN iron-line vs continuum time-lags in the lamp-post geometry
A. Epitropakis, I. E. Papadakis, M. Dovčiak +4
Context: Theoretical modelling of time-lags between variations in the Fe K emission and the X-ray continuum might shed light on the physics and geometry of the X-ray emitting re…
RoboPol: Do optical polarization rotations occur in all blazars?
D. Blinov, V. Pavlidou, I. Papadakis +23
We present a new set of optical polarization plane rotations in blazars, observed during the third year of operation of RoboPol. The entire set of rotation events discovered during…
A search for X-ray reprocessing echoes in the power spectral density functions of AGN
D. Emmanoulopoulos, I. E. Papadakis, A. Epitropakis +3
We present the results of a detailed study of the X-ray power spectra density (PSD) functions of twelve X-ray bright AGN, using almost all the archival XMM-Newton data. The total n…
Extensive X-ray variability studies of NGC 7314 using long XMM-Newton observations
D. Emmanoulopoulos, I. M. McHardy, S. Vaughan +1
We present a detailed X-ray variability study of the low mass Active Galactic Nuclei (AGN) NGC 7314 using the two newly obtained XMM-Newton observations ( and ks), toget…
