The universal shape of the X-ray variability power spectrum of AGN up to $z\sim 3$

M. Paolillo, I. E. Papadakis, W. N. Brandt +12

We study the ensemble X-ray variability properties of Active Galactic Nuclei (AGN) over a large range of timescales (20 ks $\le T\le$ 14 yrs), redshift ($0\le z\lesssim 3$), lu…
