From few to thousands: Shedding light on dark matter and dark energy with strong gravitational lenses in the era of LSST, Euclid and Roman
Strong gravitational lenses have provided great insights into the expansion history of the universe and the dark matter distribution from clusters down to sub-galactic scales. Current state-of-the-art measurements involving strong gravitational lensing are based on samples of order a dozen gravitational lenses. This current decade, with the onset of wide and deep surveys, such as LSST, Euclid, and Roman, 10,000s of gravitational lenses will be discovered. With these numbers come great opportunities and challenges. In this talk, I will go through the challenges and methods that hold promise in analyzing large samples of lenses. I will further outline the potential of new approaches that only become possible with large numbers of gravitational lenses to fully utilize the opportunities that lie ahead of us.
