The 2024 State of the LSST AGN Science Collaboration and Its European Connections

The LSST Active Galactic Nuclei (AGN) Science Collaboration (SC), currently composed of 190 members spanning the globe (with more than 50 Europeans), aims to lead many of the large-scale LSST investigations of growing supermassive black holes in AGNs. I will briefly summarize the membership and organization of the AGN SC, including its four ongoing European in-kind projects. I will then highlight its recent and ongoing activities, including contributing to survey cadence optimization, gathering and analyzing preparatory data sets (e.g., in the Deep-Drilling Fields), forecasting science results with simulations, serving on key working groups and committees, and performing outreach to the scientific community and general public. I will finally discuss future plans and describe how interested members of the European and worldwide astronomical community can become involved.
