| Abstract: |
The baryonic content of the Universe is only 4% of the cosmic mass-energy budget, but the stars and galaxies that we can directly see comprise only <10% of the cosmic baryons. The rest residing in the 'invisible' intergalactic gas that is not well understood. In this talk, I will describe our effort to study these intergalactic baryons, firstly using 3D tomography of the Lyman-alpha forest absorption at z~2-3 (the 'Cosmic Noon' of the Universe), as well as using novel fast radio burst discoveries to study them in the Local Universe. I will also describe the novel concepts of field-level inference that has been applied to these problems, and our future synergistic efforts to study the growth of structure, galaxies and gas in combined analyses. |
