Despite all my intentions to stop working on strong gravitational lensing, I keep getting accidentally pulled back, with interesting projects from Marshall and new discoveries from Tsalmantza. Today I pitched some strong lensing modeling projects to NYU graduate student Cato Sandford. The idea is to simultaneously model multi-epoch multi-band imaging (with variable PSF) with a time-varying multiply imaged quasar and the galaxy that is lensing it. That conversation is about the only real research I can report on today.
