The bias ($b$) is a parameter that relates the clustering of a set of objects with the clustering of underlying dark Matter. It has been found that b depends on various galaxy properties, this phenomenon is usually known as Galaxy Assembly Bias. In general, b depends on how the galaxies have formed. We quantify the galaxy assembly bias of simulated galaxies at $z = 0$ with stellar masses $ M_\star >10^9M_\odot h^{-1}$ from the cosmological magnetohydrodynamic simulation IllustrisTNG. We obtain the clustering-age relation, cuts in the (g-i) colors, and the specific Star Formation Rate of central and satellite galaxies separately.
