The study of the interplay between galaxy angular momentum and structures in the cosmic web is a powerful tool to constrain galaxy evolution scenarios. We study the alignments of galaxies' spin axes with respect to nearby cosmic web filaments as a function of various properties of the galaxies...

The study of the interplay between galaxy angular momentum and structures in the cosmic web is a powerful tool to constrain galaxy evolution scenarios. We study the alignments of galaxies' spin axes with respect to nearby cosmic web filaments as a function of various properties of the galaxies and their constituent bulges and discs. We exploit the SAMI Galaxy Survey to identify 3D spin axes from spatially-resolved kinematics and to decompose galaxies into their kinematic bulge and disc components. The GAMA redshift survey is used to reconstruct the surrounding cosmic filaments. The mass of the bulge is the primary parameter of correlation with spin-filament alignments: galaxies with lower bulge masses tend to have their spins parallel to the closest filament, while galaxies with higher bulge masses are more perpendicularly aligned.
