Evolution of Galaxy Bulges
I present our recent results on bulge evolution. (1) We have modeled the accretion of satellite galaxies onto disk-bulge-halo galaxies, and show that accretion-driven bulge growth generates two of the observed trends of galaxies along the Hubble sequence, namely the higher Sersic index toward more massive bulges, and the appearance of a thick disk
