SUMMARY:The discovery of Dark Energy
DESCRIPTION:Featuring Gerson Goldhaber\, LBNL\nHosted by: Lawrence Sulak\nP
	oster: http://physics.bu.edu/internal//posters/2007_Fall/05_Goldhaber.pdf\n
	\nPart of the Physics Department Colloquia Series.\n\nPAST. It is now just 
	about 10 years since the acceleration of the expansion of the Universe was 
	discovered. I will discuss how this occurred in the Supernova Cosmology Pro
	ject (SCP). \n\nPRESENT. I will mention 2 current projects:\n\nThe study of
	 SNe in galaxy clusters with the Hubble Space Telescope. Here we deal mainl
	y with elliptical galaxies and thus avoid the problem of dust in the host g
	alaxy. \nCosmological results from a compilation of most of the currently p
	ublished Type Ia SNe.\n\n\nFUTURE. A National Academy of Science committee 
	has selected JDEM as the first in line next large NASA project. The SCP has
	 proposed a 2m telescope in space (SNAP) with 9 filters (including optical 
	and infrared detectors) to study both Type Ia SNe and gravitational lensing
	. This is one of 3 proposed vehicles for the study of Dark Energy. The big 
	question is\, are we dealing with a cosmological constant or is there some 
	variation with epoch.
