Black Hole and Galaxy Evolution in the Context of Large-Scale Structures
(Placeholder for detailed content. Add more text and figures here that elaborate on AGN samples, galaxy evolution, the black-hole-to-halo-mass relation, and their connection to large-scale structures.)
Galaxies and the supermassive black holes at their centers are not isolated objects; their growth is deeply connected to the enormous dark matter halos that host them and the cosmic web they reside in. I conduct research to provide direct constraints on how supermassive black holes and galaxies co-evolve within these vast environments.
By cross-correlating samples of Active Galactic Nuclei (AGNs) with weak lensing surveys, we can measure the excess surface mass density of the halos associated with these active black holes. Understanding this black-hole-to-halo-mass relationship—and connecting it to the broader large-scale structure—helps us test cosmological simulations and reveals how cosmic environments dictate the lifecycle and growth of galaxies and black holes.
