Abstract We compare the growth in stellar mass of galaxies in the 6 2 × 10 8 M ⊙ in the epoch 8 < z < 6 had less than M * < × 10 8 M ⊙ prior to z = 8. Here too we find agreement between models and data, namely that these ≳100 Myr “bursts” had strong in situ growth at z ≤ 8 or showed (in G alacticus ) substantial stellar and/or gas-rich mergers and 30–40 Myr “starbursts,” as are common in z < 3 galaxies. We note that, if a theoretical simulation is unable to pass the test of matching the growth of “stellar mass,” any success in reproducing the luminosity function is meaningless.
Dressler et al. (Tue,) studied this question.
