Project Description
The COSMOS Lyman-Alpha Mapping And Tomography Observations (CLAMATO) survey will use the LRIS spectrograph on Keck-I to observe the Lyman-alpha forest of neutral hydrogen absorption in closely-spaced quasars and galaxies. This will allow us to create an unprecedented map of the cosmic web at z=2.3, over 11 billion light years away at the epoch of peak star formation.
