BEGIN:VCALENDAR VERSION:2.0 CALSCALE:GREGORIAN PRODID:iCalendar-Ruby BEGIN:VEVENT CATEGORIES:Lectures & Presentations DESCRIPTION:The Physics & Astronomy Colloquium Series presents Bharat Ratra of Kansas State University discussing "Spatial Curvature\, Dark Energy Dyn amics\, Neither\, or Both" on March 29.\n\n \n\nAbstract: Observations over the last two and a half decades have persuaded cosmologists that (as yet o nly indirectly detected) dark energy is by far the main component of the en ergy budget of the current universe.\n\nI review a few simple dark energy m odels and compare their predictions to observational data\, to derive dark energy model-parameter constraints and to test consistency of different dat a sets. I conclude with a list of open cosmological questions.
