Talk Enabling early science with Rubin LSST in 2025 Enabling early science with Rubin LSST in 2025

Description

I this talk I will present a forecast for the cosmological constraints expected from all the galaxy-scale strong gravitational lenses identified in the Rubin Observatory (LSST). In particular, the constraints are provided by the following SL sub-probes: lensed quasars, lensed supernovae, double source-plane lenses (DSPL), and galaxy-galaxy lens Einstein Rings, both with and without follow-up data. We plan to emulate a fully self-consistent joint hierarchical inference of cosmological parameters given a mock lens sample, and investigate the information content provided by each sub-probe. I will also talk about the challenge of the follow-up observations and coordinations with other survey facilities.
