As you might expect from a project with such an ambitious goal, HETDEX is a large collaboration. It involves astronomers, engineers, technicians, gradudate students, and others from six academic institutions in the United States and Germany.
The project began at The University of Texas at Austin, when several faculty members and senior research scientists began discussing the possibility of using large arrays of spectrographs with the Hobby-Eberly Telescope. They realized that the technique was a natural fit for probing the nature of dark energy, and began assembling a team of theoreticians, instrument designers and builders, and others to develop the technology.
Today, the team continues to grow. HETDEX not only will provide answers to one of the leading questions of modern science, it will develop the technology for exploring future problems. And it will provide a rich educational experience for graduate and undergraduate students at Texas and elsewhere, helping train the next generation of scientists.
