Title: Dark Energy: constant or time variable? (... and other open questions)
Summary: Experiments and observations over the last decade have persuaded cosmologists that (as yet undetected) dark energy is by far the main component of the energy budget of the universe. I review a few simple dark energy models and compare their predictions to observational data, to derive dark energy model-parameter constraints and to test consistency of different data sets. I conclude with a list of open cosmological questions.
All are invited!
Refreshments will be served @ 2:30 in STC 124.
