Monsters in the dark: predictions for luminous galaxies in the early Universe from the B<scp>lue</scp>T<scp>ides</scp> simulation

Using deep Hubble and Spitzer observations Oesch et al. (2016) have identified a bright ($M_{\rm UV}\approx -22$) star forming galaxy candidate at $z \approx 11$. The presence of GN-$z11$ implies a number density $\sim 10^{-6}\,{\rm Mpc^{-3}}$, roughly an order of magnitude higher than the expected value based on extrapolations from …
