DESCRIPTION:Speakers: Bharat Ratra (Kansas State University)\n\nObservatio
 ns over the last two and half decades have persuaded cosmologists that (as
  yet only indirectly detected) dark energy is by far the main component of
  the energy budget of the current universe. I review a few simple dark ene
 rgy models\, including the currently-standard ΛCDM cosmological model\, a
 nd compare their predictions to observational data\, to derive cosmologica
 l parameter constraints and to study consistency of different data sets. I
  summarize observational constraints on dark energy dynamics and spatial c
 urvature\, two parameters that extend away from the time-independent cosmo
 logical constant dark energy and flat spatial hypersurfaces of the standar
 d ΛCDM model. I also summarize observational constraints on the Hubble co
 nstant. I conclude with a list of my favorite open cosmological questions.
