AbacusSummit is the world’s largest suite of high-performance cosmological N-body simulations, developed to meet and exceed the analysis requirements of the Dark Energy Spectroscopic Instrument. These simulations allow one to predict the large-scale structure that results from a wide range of cosmological models, enabling detailed investigations of theories of cosmological structure formation and comparison to the coming decade of observational surveys.
Dark Energy Spectroscopic Instrument (DESI)
The Dark Energy Spectroscopic Instrument (DESI) consortium is conducting a five-year survey to map the large-scale structure of the Universe over one-third of the sky and 11 billion years of cosmic history, aiming to study the physics of dark energy.
GMACS - Moderate Dispersion Optical Spectrograph for the Giant Magellan Telescope is a powerful optical spectrograph that will unlock the power of the Giant Magellan Telescope for research ranging from the formation of stars and planets to cosmology.
Physics of the Primordial Universe
The Big Bang theory of cosmology successfully describes the 13.7 billion years of evolutionary history of our Universe. However, it is known that the origin of the Big Bang is incomplete. We are interested in finding out what caused the Big Bang, and the physics involved in this primordial epoch. We study physics, build models and propose observables for the primordial universe using quantum field theory, general relativity and/or string theory, and test them with data from astrophysical observations.
