Description
In this talk I will discuss several new probes and considerations for large-scale structure measurements, which go beyond the most common 2x3pt shear and galaxy clustering measurements for cosmology. Firstly, I will discuss newly discovered cross-correlations between gravitational shear and flexion, including their surprising anticommutative properties. Secondly, I will discuss our latest understanding of cross-correlations between lensing and radio intensity mapping, which do not vanish due to foreground removal as might be supposed. Finally, I will discuss the latest higher order statistics LSS techniques and results in current cosmological surveys.
