Squeezing Full-shape Dynamical Dark Energy Constraints with Galaxy Alignments
Recent 2 σ –4 σ deviations from the cosmological constant ${\rm{\Lambda }}$ suggest that dark energy (DE) may be dynamical, based on baryon acoustic oscillations and full-shape galaxy clustering (FS GC) analyses. This calls for even tighter DE constraints to narrow down its true nature. In this Lett...
