Abstract

Clustering measurements help us to investigate gravity shaping the cosmic web, galaxy-halo connection and more physical processes determining our observations on cosmological scales. Widely used 2-point statistics incorporate studying the effects on Large-Scale Structure parallel and perpendicular to observer’s line-of-sight. In this talk I will introduce results from modified ellipsoidal complementary correlation function (CF) estimators which extend the volume-averaged CF of higher orders to on/off line-of-sight analysis. The presentation will cover real-redshift space effects for dark matter as well as for galaxies and promising results concerning differentiating between General Relativity and f(R) gravity scenario.
