Astronomers utilize massive computer simulations to model cosmic evolution

Astronomers have conducted massive cosmological computer simulations, including the FLAMINGO and ASTRID projects, to model the evolution of the universe. These simulations track the interplay between ordinary matter, dark matter, and dark energy to understand how galaxies and large-scale structures emerge over time.

The FLAMINGO simulations aim to resolve tensions in the standard model of cosmology, specifically discrepancies between measurements of cosmological parameters derived from the cosmic microwave background and those obtained through gravitational lensing. By simulating the universe's components according to the laws of physics, researchers hope to identify potential systematic errors in current measurements.

Similarly, the ASTRID simulation has been utilized to model the universe from its earliest days to the present day (z = 0). This high-resolution hydrodynamic simulation helps address puzzles raised by observations from the James Webb Space Telescope (JWST), such as the unexpected presence of fully-formed galaxies and supermassive black holes in the early universe. These computational tools are essential for connecting theoretical predictions to observed data from facilities like the Euclid Space Telescope and JWST.
