• Measuring line-of-sight shear with Einstein rings

  

  Today I released a paper written in collaboration with Pierre Fleury, Julien Larena and Matteo Martinelli on how we can measure line-of-sight shear from Einstein rings. But what is line-of-sight shear, and why are we interested in measuring it in the first place? To answer these questions, let’s review the phenomenon of strong gravitational lensing.…
