For decades, the missing baryonic matter of the cosmos eluded detection, hidden within diffuse filaments spanning the vast voids between galaxy clusters. Today, an international collaboration utilizing exascale supercomputing architecture has unveiled the most detailed hydrodynamic cosmological simulation ever executed, resolving the exact spatial distribution of dark matter filaments across 100 million light-years.
Mapping the Warm-Hot Intergalactic Medium (WHIM)
Using a novel grid-based magnetohydrodynamics algorithm running across tens of thousands of GPU accelerators, the simulation tracked the gravitational collapse of over one billion dark matter particles alongside luminous gas from redshift z=120 down to the present day. The data reveals that over 50 percent of standard cosmic baryonic matter is concentrated in warm-hot intergalactic gas heated by shock waves along gravitational tendrils.
Direct Alignment with Observational X-Ray and Fast Radio Burst Data
Crucially, the simulation predictions align precisely with dispersion measure datasets collected by the CHIME radio telescope and localized Fast Radio Bursts (FRBs), as well as soft X-ray absorption spectra from the XRISM space observatory. This convergence definitively solves the missing baryon problem while constraining the mass-energy distribution of cold dark matter.
