SUMMARY:Vera C. Rubin Observatory: from Commissioning to Cosmology\, P
 hysics Department Colloquium\, Keith Bechtol
DESCRIPTION:Our observed universe is one statistical realization of th
 e fundamental laws of nature enacted on the grandest scale. As observa
 tional cosmologists\, we survey increasingly large volumes of the univ
 erse to help ascertain those laws with improved accuracy and precision
 . Experiments at the cosmic frontier have demonstrated that measuremen
 ts of the cosmic expansion history and growth of structure are sensiti
 ve to physics beyond the Standard Model\, including the nature of dark
  energy\, massive neutrinos\, the initial conditions of the Universe (
 e.g.\, inflation)\, and the particle properties of dark matter. Contin
 uing this enterprise\, the Vera C. Rubin Observatory Legacy Survey of 
 Space and Time (LSST) will catalog more galaxies and collect precision
  lightcurves for more supernovae during its first year of science oper
 ations in 2024-2025 than all previous cosmic surveys combined. The Rub
 in Observatory construction project is now actively engaged in system 
 integration\, test\, and commissioning with engineering "first light" 
 expected in mid-2023. I will discuss the pathway from commissioning to
  realizing the scientific potential of Rubin Observatory.
