very high redshift galaxies

halo mass vs. observed magnitude. UDF WFC3 observations reach a depth of ~29 in J125W.
rest UV LF at z=6, 7, 8. solid=no dust, dashed=with dust. dot-dashed=observations.

rest UV luminosity function, no feedback. solid=no dust, dashed=with dust. dot-dashed: observations.

stellar mass function at z=6. points=Stark et al. observations. red dotted=Nagamine sims (no stellar FB). dot-dashed red=SAM w/ no FB.

halo mass vs. stellar mass relation. orange lines=Behroozi et al. relations at the indicated redshifts. blue lines = Behroozi et al. at z=0.
