JWST census of Type 1 AGN from Cosmic Noon to Reionization

The origin and evolution of supermassive black holes as well as their interaction with their host galaxies still holds many unanswered questions such as the uncertainty surrounding the seeding and growth of the first supermassive black holes embedded in first galaxies. The launch of JWST was expected to shed more light on this domain by probing the low mass, low luminosity end of the active galactic nuclei (AGN) distribution - a regime missed by previous all sky surveys which were sensitive only to the brightest objects. However, first years of results have revealed some peculiar properties of this low luminosity AGN population. Among the more notable ones being their offset compared to the local black hole mass - stellar mass relation and prevalence of absorption features in their broad lines. In this talk I will present a robust sample of Type 1 AGN from the JADES survey spanning redshifts 2 to 9. I will focus on the redshift evolution of the BH - host galaxy scaling relations, the contribution of faint AGN to the UV luminosity function and the presence of overmassive black holes in the high redshift universe. In addition, I will discuss the occurance rate of Balmer absorption features in faint Type 1 AGN and Little Red Dots, focusing on the physical implications. I will also explore how deep JWST IFU data can be used to kinematically constrain BH masses out to redshift 7.
