In particular, their mass budgets in haloes in condensed phase (rho(gas)/(rho) over bar (bar) greater than or similar to 10(3), and T less than or similar to 10(5) K) are driven by gas cooling and star formation with a peak at z similar to 2. Finally, our results confirm that Ovi, Neviii, and Nv are good tracers of warm/hot and low-density gas at low redshift (rho(gas)/(rho) over bar (bar) greater than or similar to 10(3), and T greater than or similar to 10(5) K), regions that are likely to contain most of the missing baryons in the local Universe.",
