- ItemThe universal shape of the X-ray variability power spectrum of AGN up to z ∼ 3(2023) Paolillo, M.; Papadakis, I. E.; Brandt, W. N.; Bauer, F. E.; Lanzuisi, G.; Allevato, V.; Shemmer, O.; Zheng, X. C.; De Cicco, D.; Gilli, R.; Luo, B.; Thomas, M.; Tozzi, P.; Vito, F.; Xue, Y. Q.Aims. We study the ensemble X-ray variability properties of active galactic nuclei (AGN) over large ranges of timescale (20 ks <= T <= 14 yr), redshift (0 <= z less than or similar to 3), luminosity (10(40) erg s(-1) <= L-X <= 10(46) erg s(-1)), and black hole (BH) mass (10(6) <= M-circle dot <= 10(9)).
