Squeezing Full-Shape Dynamical Dark Energy Constraints with Galaxy Alignments
A Fisher forecast shows that including galaxy intrinsic alignments alongside full-shape galaxy clustering improves the dark energy figure-of-merit by 42-57% and the primordial amplitude constraint by 17-19% for a PFS-like survey.
