27. ELUCID - Exploring the Local Universe with reConstructed Initial Density field

Huiyuan Wang (USTC)

11/3/23, 9:00 AM

Cosmological Simulation

Talk

I will introduce our series of works related to the ELUCID project that reconstructs the initial condition of the local Universe and studies large-scale structures and galaxy formation using constrained simulations. I will first briefly review the reconstruction methods developed in the literature. Then, I will introduce our own method in detail. After that, I will introduce several works...

15. The CAMELS project

Francisco Villaescusa-Navarro

11/3/23, 9:25 AM

Cosmological Simulation

Talk

I will present and describe the CAMELS project, whose aim is to build bridges between cosmology and galaxy formation by combining numerical simulations and machine learning. Containing a set of more than 10,000 simulations, both N-body and state-of-the-art hydrodynamic simulations, it is currently the largest dataset of cosmological simulations designed to train artificial intelligence...

62. How cosmology influences baryonic feedback: lessons from FLAMINGO

Willem Elbers (Durham)

Tensions & Challenges

Talk

The large-scale distribution of matter is influenced both by cosmology and by astrophysical processes, such as feedback from active galactic nuclei (AGN), which themselves are not independent of cosmology. This coupling gives rise to non-factorizable corrections to matter power spectrum, which will affect the cosmological interpretation of upcoming weak lensing surveys, such as Euclid and...
