• •A new technique called field-level inference (FLI) can analyze 3D maps of galaxies without compressing the data
• •FLI could reveal asymmetries in the quantum fluctuations in the big bang that led to over-densities that grew under gravity into galaxies
• •FLI could also reveal anomalies in the gravitational evolution of galaxies in the more recent universe that could reveal details about dark matter, or in fact gravity itself

A new way to study 3D maps of galaxies in the cosmos without compressing the data is revealing new information about the dark universe. The research, led by astronomer Minh Nguyen of the University of Tokyo, utilizes powerful computer algorithms that are able to compare the relative positions of galaxies in a 3D map of the universe with detailed simulations that depict the growth and behavior of galaxies and haloes of dark matter.
