Dark Energy

The nature of Dark Energy is one of the greatest mysteries in science today. It was discovered in 1998, when scientists found that the expansion of the universe is accelerating. We call the force driving this expansion Dark Energy, but beyond that we know very little. LSST will produce a unique dataset of billions of galaxies, which will allow us to measure how Dark Energy behaves over time with unprecedented precision. The LSST dataset will also enable us to tackle several other questions in cosmology and fundamental physics.

The LSST Dark Energy Science Collaboration will prepare for and carry out a variety of cosmological analyses with the LSST survey. In advance of LSST’s first observations, DESC will help prepare for LSST science analysis, make synergistic connections with ongoing cosmological surveys and provide the dark energy community with state of the art analysis tools.
