Galaxy clusters in the VIDEO fields: detection and characterisation in the context of MOONRISE
Pierre Galois, Christophe Benoist, Gianluca Castignani +21
We analyse the cluster content of the XMM-LSS and CDFS VIDEO fields which are expected to be partially covered by the upcoming MOONRISE survey. Using AMI…
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…
Ensemble power spectral density of SDSS quasars in UV/optical bands
Vincenzo Petrecca, Iossif Papadakis, Maurizio Paolillo +2
Context: Quasar variability has proven to be a powerful tool to constrain the properties of their inner engine and the accretion process onto supermassive black holes. Correlations…
Exploring black-hole scaling relations via the ensemble variability of Active Galactic Nuclei
A. Georgakakis, I. Papadakis, M. Paolillo
An empirical model is presented that links, for the first time, the demographics of AGN to their ensemble X-ray variability properties. Observations on the incidence of AGN in gala…
Measuring X-ray variability in faint/sparsely-sampled AGN
V. Allevato, M. Paolillo, I. Papadakis +1
We study the statistical properties of the Normalized Excess Variance of variability process characterized by a red-noise power spectral density (PSD), as the case of Active Galact…
Probing BH mass and accretion through X-ray variability in the CDFS
V. Allevato, C. Pinto, M. Paolillo +4
Recent work on nearby AGNs has shown that X-ray variability is correlated with the mass and accretion rate onto the central SMBH. Here we present the application of the variability…
