Extending the range of probes of large-scale structure 

In this talk I will present some of the latest constraints on cosmological physics from large-scale structure measurements, particularly from the Dark Energy Survey. These constraints have been made using probes including galaxy clustering, cosmic shear and galaxy-galaxy lensing; but then what can we do beyond that? I will discuss some of the ways in which further adventures can be attempted: examining cross-correlations between optical surveys and CMB, radio continuum and HI surveys; and using brand new lensing cross-correlations.
