INPA SEMINAR TALK
Date: Friday, May 3, 2024
Time: 12:00 PM – 1:00 PM
Location: Sessler Conference Room–50A-5132 [Hybrid and In-Person]
Speaker: Carolina Cuesta-Lazaro (Harvard)
Title: Big Data cosmology meets AI
Abstract: The upcoming era of cosmological surveys promises an unprecedented wealth of observational data that will transform our understanding of the universe. Surveys such as DESI, Euclid, and the Vera C. Rubin Observatory will provide extremely detailed maps of billions of galaxies out to high redshifts. Analyzing these massive datasets poses exciting challenges that machine learning is uniquely poised to help overcome. In this talk, I will highlight recent examples from my work on probabilistic machine learning for cosmology. First, I will explain how a point cloud diffusion model can be used both as a generative model for 3D maps of galaxy clustering and as a likelihood model for such datasets. Moreover, I will present a generative model developed to reconstruct the dark matter cosmic web from biased galaxy clustering observations, in a probabilistic manner. And finally, I will introduce ongoing work on developing fast, differentiable, and accurate hybrid physics-ML simulators for N-body and hydrodynamical simulations. When combined with the wealth of data from upcoming surveys, these machine learning techniques have the potential to provide new insights into fundamental questions about the nature of the universe.
