Description
galactic.ai — The New Frontier in Cosmology and Astrophysics
Galaxy surveys of the next decade will observe billions of galaxies over unprecedented cosmic volumes. They will produce detailed 3D maps of galaxies that encode the growth and expansion histories of the Universe. They will also observe photometry and spectroscopy that encode how galaxies and quasars evolve across cosmic history. Recent developments in machine learning (ML) and AI provide unique opportunities to fully extract this information. I will illustrate how the galaxy surveys I am leading (DESI, PFS), combined with the cutting-edge ML/AI methods I have pioneered, will address fundamental questions in cosmology and about galaxies that are out of reach with conventional methods. I will show how to test the standard "Lambda-CDM" cosmological model in new regimes and with unmatched precision to probe the nature of dark energy. Furthermore, I will demonstrate how my ML/AI methods can extract detailed properties of millions of galaxies to precisely track their evolution, constrain the physical processes that drive their evolution, and unlock the discovery space of the next-generation surveys.
