Glossary

HETDEX

The Hobby-Eberly Telescope Dark Energy Experiment. It will use an upgraded Hobby-Eberly Telescope, along with a suite of spectrographs known as VIRUS, to map a section of the universe as it existed 9 billion to 11 billion years ago. It will map one million galaxies or more and measure their motion through space, providing a probe of the nature of dark energy.
