If you have a question about this talk, please contact Ilya Mandel. I will discuss probes of the intergalactic medium measuring both the largest and smallest scale effects in the extragalactic universe. The Lyman-alpha forest along the line-of-sight to background quasars is measured providing a new kind of survey. The BOSS survey (as part of SDSS -III) has probed more than 60,000 Gigaparsecs in path length and is still growing. We have made the first measurements of baryon acoustic oscillations on 150 Megaparsec scales to probe the expansion of the universe, and have seen evidence of clumping in regions around galaxies on 30 parsec scales. I will discuss the future of such surveys and the key role the UK will play as part of a future WEAVE survey on the WHT . This talk is part of the Astrophysics Talks Series series.
