GLASS: science highlights and lessons for JWST

Tommaso Treu (UCLA)

Strong lensing studies of galaxy clusters provide unique insights into the properties of dark matter in the cluster itself, and on the distant universe via the magnification of background sources. Even in the era of JWST, gravitational telescopes will remain the only way to study faintest and most compact sources. The Grism Lens-Amplified Survey from Space (GLASS) is a large HST cycle-21 program targeting for grism spectroscopy 10 massive galaxy clusters with extensive HST imaging from CLASH and the Frontier Field Initiative. I will present some of the highlights from GLASS. I will conclude by discussing the lessons learned from GLASS and their implications for the optimization of the science return from the JWST mission.
