The Department of Astronomy at Ohio State, is delighted to invite you to our fall FOSAA event, all about the DESI cosmology survey. DESI, the Dark Energy Spectroscopic Instrument survey, is changing the way we think about dark energy. Ohio State is a key player in this survey, from building instruments, writing software, observing, and doing the science.
