Temperature profile as a function of distance from filament spines. The pink, blue, and brown bars indicate the 1σ interval of the log-normal distribution of the median values of individual filaments within each distance bin for the high δ_LD, full, and random filament samples, respectively. The red and purple squares mark the peak of each respective distribution. The solid yellow line is the best-fit temperature profile model fitted to the high δ_LD sample. The brown dashed line indicates the background temperature, while the black dashed lines mark the temperature limits of the WHIM (log T(K) = 5) and the hot WHIM (i.e. missing baryons, log T(K) = 5.5).
