Meet ASTRID, the New High-Resolution Cosmological Simulation
Developing

“The most important information about our recent study is that we’ve evolved the ASTRID simulation to z = 0, and that this data is available,” lead author Yihao Zhou said in a press release. So how will this large, high-resolution simulation address our questions about the Universe, especially the early Universe as revealed by the JWST, with its surprisingly massive black holes?
“We can look into the questions posed by JWST data using this very large volume of ASTRID simulations, with quite amazing resolution and physical realism, that allows us to make predictions and understand some of the current puzzles that are coming through,” Di Matteo said.
