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…
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…
Statistical properties of Fourier-based time-lag estimates
A. Epitropakis, I. E. Papadakis
The study of X-ray time-lag spectra in active galactic nuclei (AGN) is currently an active research area, since it has the potential to illuminate the physics and geometry of the i…
Signatures of X-ray reverberation in the power spectra of AGN
I. Papadakis, T. Pechacek, M. Dovciak +3
We compute fully relativistic disc response functions in the case of the "lamp-post" geometry using the full observed reflection spectrum for various X-ray source heights, disc inc…
