Meet ASTRID, the New High-Resolution Cosmological Simulation

The ASTRID cosmological simulation has run from the Universe's early days up to the present day, z=0. ASTRID is larger than some other simulations, and smaller than others. But with a higher number of particles, it has higher-resolution than its fellows. Among other things, this can tell astronomers where to look for gravitational waves from black hole mergers with future GW observatories.
