Two-dimensional projection of a 10 Mpc slice of the cosmic web in TNG50 at z = 2 (in the x-y plane), with the full box on the left and a zoomed-in 10 × 10 Mpc region on the right. The filaments (curves whose color and thickness are proportional to the 1D line density, as defined in H24) and galaxies (markers) are overlaid on the integrated DM overdensity (in the z-direction). In the zoomed-in panel on the right, prolate, oblate, and spheroidal galaxies are represented by cyan diamonds, lime green octagons, and magenta circles, respectively (the galaxy markers are not to scale). MCPM-based filaments can accurately trace the underlying DM distribution and reconstruct from the spatial distribution of galaxies alone.
