ESASky: The whole of space Astronomy at your fingertips

Giordano, F.; de Teodoro, P.; Baines, D. +11 more

ESASky is a new science-driven discovery portal for all ESA astronomical missions that gives users worldwide a simplified access to high-level science-ready products from ESA and other data providers. The tool features a sky exploration interface and a single/multiple target interface, and it requires no prior knowledge of specific details of each…

Unveiling the physics of AGN through X-ray variability

González-Martín, O.; Márquez, I.; Masegosa, J. +1 more

Although variability is a general property characterizing active galactic nuclei (AGN), it is not well established whether the changes occur in the same way in every nuclei. The main purpose of this work is to study the X-ray variability pattern(s) in AGN selected at optical wavelengths in a large sample, including low ionization nuclear emission …

Probing relativistic effects in the central engine of AGN

Miniutti, G.; Sanfrutos, M.

Active Galactic Nuclei (AGN) are perfect laboratories to check General Relativity (GR) effects by using Broad Line Region (BLR) clouds eclipses to probe the innermost regions of the accretion disk. A new relativistic X-ray spectral model for X-ray eclipses is introduced. First we present the different observables that are involved in X-ray eclipse…
