Observations from the large galaxy surveys, especially the measurements of galaxy clustering and weak gravitational lensing have emerged as a strong probes of cosmology in the last decade and a half. Joint analysis of galaxy clustering and galaxy position-lensing (g-L) cross correlations provides a direct measurement of the clustering of matter in the universe and thus a strong test of models of<br>cosmology, independent of the galaxy bias. Combined with measurements of galaxy velocities from redshift space distortions, these measurements can also test the models of gravity
