The next webinar of the “Athena X-ray Advances: ASST & ACO Science Webinars” is forseen on the 27th of April at 15 CEST. This time Antonis Georgakakis (National Observatory of Athens) will give the webinar entitled "Forward Modelling the Energetic Universe”.

Abstract: We currently witnessing a dramatic increase in the quality and quantity of observations available for studying the demographics of supermassive black holes within galaxies. The flux of new data opens new opportunities for painting a detailed physical description of the accretion history of the Universe and exploring the conditions that trigger accretion flows onto the supermassive black holes of galaxies. These developments call for new modeling techniques to interpret the observations and conclude on the physics at play. I will present a data-driven semi-empirical model of active black hole populations (Active Galactic Nuclei) in cosmological volumes that enables robust hypothesis testing by forward-modeling observations of the energetic Universe. I will show how this approach helps us learn about the role of the environment (i.e. local density of galaxies) in activating supermassive black holes at the centres of galaxies and discuss future prospects related to the Athena X-ray observatory.
