Colloquium:Enrique Paillas: "Fundamental Cosmology with Galaxy Clustering"

Galaxy clustering provides a precision probe of the expansion rate of the Universe and the growth of structure within it, enabling tests of dark energy and gravity that are highly complementary to other cosmological probes. In this talk, I will review the latest findings of galaxy clustering science with the Dark Energy Spectroscopic Instrument, covering the dynamical dark energy findings from baryon acoustic oscillations, the growth rate measurements from a full-shape analysis of the galaxy power spectrum, and our new prospects for accessing the non-linear, non-Gaussian regime using simulation-based forward models powered by deep learning.
