| Outline of Research at the Start |
The basic product of our program is the cosmic web generated by the Lyman-alpha forest IGM tomography created from the background galaxies. This will be used to study the galaxy properties as a function of the cosmic web. We will also identify galaxy protoclusters and study their thermal properties as probed by the absorption, which will constrain AGN feedback models. In the longer term, we will develop field inference techniques, which will let us run hydrodynamical simulations based directly on the data set.
