Filaments in the constrained simulation compared to filaments in observations. The left column shows the case of a mass selected galaxy sample in the constrained simulation, the right column shows the case of a magnitude selected galaxy sample. In each panel, simulated galaxies are shown as gray points. Blue lines are filaments from Malavasi et al. (2020b) in supergalactic coordinates, the red square marks the position of the Coma cluster. Dark red lines are filaments obtained in the simulation with a variety of DisPerSE parameter combinations, namely: SD0−2σ (top row), SD0−3σ (second row), SD1−2σ (third row), SD1−3σ (bottom row). Circle and triangles mark the positions of critical points (in observations and simulations, respectively) and are color-coded according to their type (red: maxima, green: type 2 saddles, brown: bifurcations). This figure shows the SGX-SGZ projection (in this projection, the increasing redshift direction is along the y axis). The observed northeast and west filaments are marked for reference.
