Speaker: Wendy Freedman (Carnegie Observatories)

Title: Cecilia Payne-Gaposchkin Lecture:
Measuring Cosmological Parameters

Abstract: I will discuss measurements of cosmological parameters, with particular focus on measurements of the Hubble constant and dark energy. I will also discuss some of Cecilia Payne Gaposchkin's contributions to the study of Cepheid variables. I will give an update on the status of the Carnegie Supernova Program, a project to followup type I and type II supernovae using the Swope, Dupont and Magellan telescopes at Las Campanas. Finally, I will describe our joint current plans for building a 20-meter-class optical telescope, the Giant Magellan Telscope.
