The ensemble broad-frequency power spectrum of Stripe-82 quasars from multiple surveys
Vincenzo Petrecca, Iossif E. Papadakis, Maurizio Paolillo +5
Variability is a striking features of quasars, observed at all timescales wavelengths. Studying its properties and the correlations with the physical parameters (e.g. black hole ma…
Characterising the X-ray variability of QSOs to the highest Eddington ratios and black hole masses with eROSITA light curves
Antonis Georgakakis, Angel Ruiz, Johannes Buchner +9
An important diagnostic of the inner structure of accretion flows onto supermassive black holes are the stochastic flux variations at X-ray wavelengths. Despite its significance, a…
Continuum optical-UV and X-ray variability of AGN: current results and future challenges
Maurizio Paolillo, Iossif Papadakis
Active Galactic Nuclei (AGN) are believed to be powered by accretion of matter onto a supermassive black hole. A fundamental ingredient in shaping our understanding of AGN is their…
