The 32nd Texas Symposium on Relativistic Astrophysics

7. Cosmology with large-scale structure

Rationale of the Mini-Symposium:

We are in an exciting era of precision cosmology with a new wave of large-scale structure (LSS) surveys from both ground-based and space telescopes. With the torrential influx of observational data expected in the near future, we anticipate a significant LEAP in our understanding of the cosmos, with sub-percent constraint on the key cosmological parameters (e.g., the expansion and growth of the Universe, nature of dark energy, and the physics of light relics) and potentially decisive evidence of new physics at the largest scales or in the early epochs (e.g., modified gravity, early galaxy formation, and inflation). In order to maximize the scientific outcome from these LSS surveys, this mini-symposium on LSS will bring together active experts from the globe, reviewing the challenges and opportunities in the survey design, data analysis, theoretical modelling, and simulation techniques. We expect the interactions between different survey collaborations in this mini-symposium will build better synergies and shape new perspectives, thereby accelerating the LSS community into a hyper-precision cosmology in the 2030s.

 

Topics:

 

1. Latest results/developments from ongoing and upcoming LSS surveys

4. Emulating the Universe: challenges in the galaxy-halo connection and numerical simulations 

2. Advanced statistical/machine learning methods for extracting cosmological information

3. Prospects for detecting new physics with future surveys
