Tracing the AGN-Merger Connection: insights from cosmological simulations and JWST mock observations
Hannah Jhee, Ena Choi, Rachel S. Somerville +6
Galaxy mergers have long been proposed as a mechanism for funneling gas toward galactic centres, potentially triggering accretion onto supermassive black holes (SMBHs) and igniting…
