Quasar Microlensing Statistics and Flux-ratio Anomalies in Lens Models
Precise lens modeling is a critical step in time delay studies of multiply imaged quasars, which are key for measuring some important cosmological parameters (especially H _0 ). However, lens models (in particular those semi-automatically generated) often show discrepancies with the observed flux ra...
