WebStrong-lens time delays have been widely used in cosmological studies, especially to infer H0. The upcoming LSST will provide several hundred well-measured time delays from the light curves of lensed quasars. However, due to the inclination of the finite AGN accretion disk and the differential magnification of the coherent temperature fluctuations, the … WebRegarding the nuclear continuum, we ﬁnd a chromatic behaviour of BA, which roughly varies from ˘5 a number of microlensing events on timescales of 50–100 d. Fortunately, … WebLSST will open a new era in the monitoring of gravitationally lensed quasars. By providing well-sampled multicolor light curves, LSST will allow us to cleanly separate microlensing by stars from macro/milli-lensing by dark matter halos and substructure in a large sample of strong lenses. We discuss how chromatic microlensing light curves from LSST will let … ground rules for huddles
