Disc star formation rates at z ∼ 4 are about as high as the peak star formation rates in ma jor mergers at later redshifts (in our simulations mergers start being important at z ∼ 2).
Is AGN feedback necessary to form red elliptical galaxies?
The suppression of star formation, which has moved the galaxy to the red sequence, is due to the combination of two physical phenomena: the shutdown of cold mode accretion by shock heating, and AGN feedback quenching star formation in galaxy mergers.
Is AGN feedback necessary to form red elliptical galaxies?
Even if these results do not favor a specific formation scenario, they suggest that planetary formation might be more complex than what has been proposed so far, perhaps with two mechanisms at work and one or the other dominating according to the stellar mass.
Testing planet formation theories with Giant stars
Since giants do not show a dependence of planet formation on metallicity and widen the range of stellar masses observed, we propose that there may be a strong dependence of planet formation on stellar mass.

Radio-inferred star formation rates (< SFRradio >= 970 M⊙ yr−1) suggest much higher star-formation efficiencies than are found for SMGs, and shorter gas depletion time scales (∼11 Myr), much shorter than the time required to form their current stellar masses (∼160 Myr; ∼1011 M⊙ ).
