Left: Comparison of the projected emission profiles from observations and simulations. The observed stacked eROSITA profile from this work is shown in purple error bars. The profiles extracted from the TNG300-1 simulation are shown as a cyan band. The TNG300-1 profile is more centrally peaked than the observed profile. For comparison, profiles of The Three Hundred Gizmo-Simba and Gadget-X simulations from Li et al. (2025) are shown as dashed and dotted green lines, respectively. Right: Best-fit gNFW gas number density profile 1σ posterior range (purple) and the range of individual fittings of the four wedges (red). We overplot the TNG300-1 gas number density profile in the off-filament directions (cyan-hatched region).
