ASTRID Z=0

Caption

Researchers completed the largest yet cosmological hydrodynamic simulation, called ASTRID, that traces the evolution of the universe from its earliest time to the present, designated as z = 0 and referring to a zero redshift of star light. Visualization shown of the ASTRID simulation at z = 0. The underlying background is the dark matter density, with the blue zoom showing the most massive dark matter halo in ASTRID; inset showing a trichromatic gas map of temperature, neutral hydrogen gas fraction, and metallicity; stellar density inset; and mock observations for the Hubble Space Telescope Wide Field Camera.
