Description
Precision measurements of cosmic expansion and the large-scale distribution of matter transform the universe into a laboratory for studying fundamental physics. Measurements of the “late universe,” through Stage-III dark energy experiments and the “early universe” through the Cosmic Microwave Background (CMB) reveal a universe that is best described by the Lambda CDM concordance cosmological model. These measurements show that the evolution of the universe is governed by Dark Matter and Dark Energy, neither of which are constituents of the Standard Model of Particle Physics. Discoveries from planned Stage-IV programs will provide a path for further exploration of fundamental physics in the cosmos. After the completion of DESI, LSST, and the upcoming CMBS4, future observations will need to 1) survey larger volumes to measure a substantial number of spatial modes to improve cosmological measurement precision, 2) characterize spatial modes over a large range of scales for sensitivity to a full suite of cosmological parameters, and 3) map the universe across a broader range in redshift to directly measure the evolution of the cosmos across all epochs. The potential for these future surveys is unprecedented and requires investment into R&D now to develop enabling instrumentation. This talk describes the process we have followed for gathering community input and the priority research directions and related R&D that we have identified as needed to prepare for Stage V experiments.
