Baryons hidden in the cosmic web, and in particular in the warm/hot intergalactic medium (WHIM,) may help solve the missing baryon problem. Increasingly detections of intergalactic OVI absorption features in quasar spectra are coupled with follow-up galaxy redshift surveys of the absorber neighborhood. The availability and analysis of these systems, the prospect of new high-resolution low-energy X-ray spectroscopic observations of the cosmic web, as well as higher resolution large scale simulations which include the effects of galactic superwind feedback and non-equilibrium ionization, compel us to revisit the theoretical picture of the baryons in the cosmic web. We use a modified computer vision algorithm to identify and extract structures in large-scale simulations (clusters, filaments, voids.) We present the redshift history and structure dependence of the temperature-density distribution of the intergalactic medium (IGM). Our understanding of the physical properties and extent of IGM structures is enhanced by progressing beyond a threshold-based definition of the components of the IGM and leads to a clearer interpretation of their role in the evolution of galaxies and of their signature in current and future observations.
