Cosmology from the Large-Scale Structure with Cosmic Surveys
The LCDM model has been extraordinarily successful, yet we know that it must fail at some point, and that we will learn something new when it does. In the past 20 years, the cosmology community has worked hard to make ever more precise measurements of the LCDM parameters using large datasets from cosmic surveys. In this talk I will focus on one particular area of this effort using large-scale structure (galaxy clustering and weak gravitational lensing) to constrain cosmology. With the advance of modern galaxy surveys such as the Dark Energy Survey (DES), we are now at a point where the canonical approach is systematics-limited and there is significant challenges going forward for us to maximally exploit the information in the next generation of galaxy surveys such as the Rubin Observatory’s Legacy Survey of Space and Time (LSST). I will present some of the efforts we are embarking to overcome this potential bottleneck with an eye on the unprecedented datasets on the horizon.
