Cosmological Gravity on All Scales | Sankarshana Srinivasan

Sankarshana Srinivasan tells us about his work building the framework to constrain (or detect!) modified gravity using upcoming surveys. Building on earlier work developing model independent modified gravity simulations, Shankar now shows how a clever transform (the BNT transform) is able to better isolate the weak-lensing kernel, meaning one can more cleanly cut out the fully messy non-linear scales without losing too much usable information. We're all looking forward to the talk in 3-5 years' time applying these methods to Euclid and LSST data!
