Growth of Massive Bulges by Mergers of Dense Satellites
We present merger models suggesting that bulge growth via accretion of dense satellites generates two of the observed trends of galaxies along the Hubble sequence, namely the increase of Sersic index toward more massive bulges, and the appearance of a thick disk with higher scale length than that of the thin disk. We argue that bulges with
