  • The correlation between the spins of dark matter halos and the large-scale structure (LSS) has been studied in great detail over a large redshift range, while investigations of galaxies are still incomplete. Motivated by this point, we use the state-of-the-art hydrodynamic simulation, Illustris-1, to investigate mainly the spin-LSS correlation of galaxies at a redshift of z = 0. We mainly find that the spins of low-mass, blue, oblate galaxies are preferentially aligned with the slowest… CONTINUE READING
