The Dark Energy Spectroscopic Instrument (DESI) will measure the effect of dark energy on the expansion of the universe, and evolution of the large-scale clustering of matter.  It will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3-dimensional map spanning the nearby universe to 10 billion light years. In particular, a million quasar spectra will be able to probe the earliest epoch between the peak of the star formation and the cosmic dawn. In these far reaches, when the Universe celebrated its first billion-th birthday, the growth of structure and the expansion of the Universe are imprinted on the intergalactic medium (IGM; see link). KICC researchers are leading the effort to understand the matter distribution at these early times. Our programme is aimed at tracing the matter content and growth of structure in the era between the present-day distribution of galaxies and the far away primary Cosmic Microwave Background (CMB; see link).
