Effects of Baryonic Feedback on the Cosmic Web

Understand

We study the effect of baryons on the cosmic web -- halos, filaments, walls, and voids.

• To do so, we apply a modified version of NEXUS, a cosmic web morphological analysis algorithm, to the IllustrisTNG simulations.
• We find that halos lose more than $10\%$ of their mass due to baryons, mostly to filaments and a small portion to walls and voids.
• However, the mass transfer does not significantly shift the boundaries of structures, leaving the volume fractions of the cosmic structures largely unaffected.
