Alignments between Galaxies and the Cosmic Web at z ∼ 1–2 in the IllustrisTNG Simulations

Alignments between Galaxies and the Cosmic Web at z ∼ 1–2 in the IllustrisTNG Simulations

Galaxy formation theories predict that galaxy shapes and angular momenta have nonrandom alignments with the cosmic web. This leads to so-called intrinsic alignment between pairs of galaxies, which is important to quantify as a nuisance parameter for weak lensing. We study galaxy–cosmic web alignment...
