Unveiling the AGN-galaxy connection at high-z with NIKA2 and radio facilities
The relationship between supermassive black hole (SMBH) accretion and star formation has lead to controversial studies claiming that Active Galactic Nuclei (AGN) activity might both quench and enhance galaxies' star-forming content. Especially at high redshift (z>2), their interplay is still poorly understood, also due to the lack of accurate estimates of star formation rate (SFR) and AGN power in active galaxies. The unique synergy between NIKA2 and current/upcoming (VLA, VLBA, SKA) radio facilities will enable us (i) to calibrate IR and radio emission as SFR tracers at z>2 via the infrared-radio correlation; (2) to better isolate the AGN contribution via panchromatic SED-fitting; (3) to ultimately explore the relationship between AGN and star formation with unprecedented accuracy. I will present the latest results obtained from deep radio surveys in this context, and discuss the exciting prospects with NIKA2.
