Astronomy is entering a new era. With ground- and space-based telescopes equipped with increasingly more sensitive cameras and instruments, enabling surveys, such as Kepler, Gaia and DES, SDSS, DESI, LSST, Euclid and WFIRST, that are discovering thousands of planets and millions of stars and galaxies, we are able to seek answers to fundamental questions about the origin and evolution of the universe. Cosmology X Data Science is a group that looks into all these datasets, develop new methods and ideas to answer fundamental questions of our cosmos.
We train a neural network model to predict the full phase space evolution of cosmological N-body simulations. Its success implies…
arXiv:2206.04573We build a field level emulator for cosmic structure formation that is accurate in the nonlinear regime. Our emulator consists…
