"Exploring the z~2.3 Cosmic Web with 3D Lyman-Alpha Forest Tomography" The hydrogen Lyman-alpha forest absorption, seen along the line-of-sight to bright distant quasars, has been an important probe of the high-redshift (z>2) cosmic web. In recent years, we have conducted Keck observations targeted instead at the Ly-a forest absorption of z~2-3 star-forming galaxies at ~24mag. This allows us to measure Ly-a forest absorption across a grid of sightlines separated by only ~2-3Mpc/h in the transverse direction and perform a reconstruction of the 3D absorption field which traces the underlying cosmic web. I will describe our latest observations which detected a galaxy protocluster at z=2.44 in the COSMOS field and characterized its properties. I will also describe simulation analysis forecasting the recovery of voids, sheets and filaments of the z~2 cosmic web with large-volume surveys over the next few years.
