These BAO measurements are beautifully complemented by the results of the SDSS - II Supernova Survey, which has provided the most precise measurements yet of cosmic expansion rates over the last four billion years.
«The results from BOSS provide a solid foundation for even more precise future BAO measurements, such as those we expect from the Dark Energy Spectroscopic Instrument (DESI),» says Natalie Roe, Physics Division director at Berkeley Lab.
