Jose Luis Bernal (Barcelona U.) "Synenergies and Fundamental Physics from the Large Scale Structure
January 29, 2019 @ 4:00 pm - 5:00 pm
Abstract:
Galaxy surveys and the study of the Large Scale Structure (LSS) have played an important role in establishing the standard cosmological model, LCDM, and will push the envelope of observational cosmology the next decades, thanks to experiments such as DESI and Euclid. In this talk, I will show how we can use LSS observations and techniques to address the tension in the Hubble constant, the origin of supermassive black holes and the nature of dark matter.
Furthermore, the ever larger volumes surveyed by next-generation galaxy surveys will enable access to the ultra-large scales, where signatures of General Relativity and inflation are significant. This will allow us to probe the nature of gravity and the very first instants of the Universe, but also requires a very specific methodology, which I will discuss during the talk.
