"Supermassive Black Holes through Cosmic time:

from current surveys to eROSITA-Euclid AGN Synergies"

(eEASy)

An FP7 funded Career Integration Grant (FP7-PEOPLE-2012-CIG 321913)

Beneficiary: Dr. Marcella Brusa

Host Institution: Alma Mater Studiorum / Università di Bologna

Funding period: 2013-2016 (4 years)

Funding: 100.000 euro

Objective:

Understanding how the first active galaxies (AGN) and quasars formed in the early Universe and how they evolved along Cosmic Time is a major observational and theoretical effort. Despite the progress made in recent years, often sparse and not always conclusive, we do not yet have a clear consistent picture of when did SuperMassive Black Holes start to accrete, which growth modes occur, and under what conditions. What is required is a systematic analysis and interpretation of high-quality multi-wavelength data on a sample as large as possible of representative AGNs. I will exploit X-ray, optical, infrared and millimeter data from different multi-wavelength survey I am already involved in and foresee an efficient and timely use of newly inaugurated facilities such, as ALMA, X-Shooter, WFC3, LUCIFER among others. With these data I will construct the largest, homogeneous and complete sample of AGN to date, needed to address the main objectives of this proposal: 1) determine the AGN bolometric luminosity function, and study its evolution with the cosmic time; 2) measure the incidence of mergers and smooth processes for the triggering AGNs; 3) study the effect of AGN feedback on galaxy growth; 4) provide the first significant samples of high-z AGN to be used as constraints on BH formation models; 5) define optimal strategies to exploit synergies between two upcoming all-sky surveys, eROSITA and Euclid.
