| Popis: |
A sizeable part of the observation time of the ESA flagship X-ray observatory Athena is expected to consist of a multi-tiered survey of the extragalactic sky. This is expected to contribute significantly to the understanding of the Hot and Energetic Universe, the main Athena science theme. One of the expected outcomes of the survey is the detection and characterisation of Compton-Thick (CT) AGN at the heyday of star formation and supermassive black hole growth in the Universe, z~1-3. We will discuss here the capabilities of Athena for characterising the luminosity and column density of moderately CT AGN for different configurations of the survey and angular resolutions of Athena. AGN activity is often manifested as outflows, which may affect significantly their host galaxies, as postulated by many models of galaxy formation and evolution. The Athena survey is expected to reveal many instances of nuclear outflows among the general AGN population. We will also show how the survey will allow to constrain the prevalence and physical characteristics (column density, ionisation...) of these outflows. |
