The study of the interplay between galaxy angular momentum and structures in the cosmic web is a powerful tool to constrain galaxy evolution scenarios. Taking advantage of the Integral Field Spectroscopic SAMI galaxy survey and the GAMA redshift survey, I will present measurements of the kinematic alignments of the galaxies’ spin axes with respect to nearby cosmic filaments as a function of various galaxy properties. The mass of the bulge is the primary parameter in determining these spin-filament alignment. I will discuss these findings in comparison to secular star formation quenching and in terms of possible evolution pathways for galaxies.
