Colloquium – David Schlegel’s “The Dark Energy Spectroscopic Survey (DESI) and Beyond”

The Dark Energy Spectroscopic Survey (DESI) and Beyond
Abstract:
The Dark Energy Spectroscopic Instrument (DESI) is mapping the sky with a 5000-fiber robotic focal plane and 10 optical spectrographs. I will describe the challenges in construction, installation, commissioning, operations, and data reduction. The 13 million galaxies mapped in the first year already promises to improve our understanding of cosmic expansion and dark energy.
