deg. in the redshift range of , targeted from HSC spectroscopy. In the South, 4MOST,12 on the VISTA telescope at the European Southern Observatory’s Paranal site, will complement the effort of DESI by carrying out several spectroscopic surveys which will allow us to tackle some of the open questions in this area. While the Cosmology Redshift Survey (Richard et al.) can be expected to yield similar targets as those of DESI, WAVES (Driver et al.) will be unique in seeking high-completeness over relatively modest volumes. WAVES-Wide (1200 sq. [...] There, we argued that intrinsic alignments are sensitive to cosmology even on linear scales and they can potentially constrain models out of the reach for two-point clustering statistics. Some works have already provided cosmological constraints from galaxy alignments which could be improved by the use of a multi-tracer strategy. But how to optimally split samples or perform shape measurements to enable the multi-tracer technique is an open question. Beyond two-point statistics offer an avenue to extract more information from galaxy shapes, whether from intrinsic alignments or weak lensing effects. How much more information can be extracted compared to the two-point case remains to be properly quantified.
