z∼ 7–10 Galaxies in the HUDF and GOODS Fields: UV Luminosity Functions
Open accessAbstract
We use all available deep optical ACS and near-IR data over both the HUDF and the two GOODS fields to search for star-forming galaxies at z ≳ 7 and constrain the UV LF within the first 700 Myr. Our data set includes ~23 arcmin 2 of deep NICMOS J + H data and ~248 arcmin 2 of ground-based (ISAAC+MOIRCS) data, coincident with ACS optical data of greater or equal depths. In total, we find eight ∼ 7.3 z -dropouts in our search fields, but no z ∼ 9 J -dropout candidates. A careful consideration of a wide variety of different contaminants suggest an overall contamination level of just ~12% for our z -dropout selection. After performing detailed simulations to accurately estimate the selection volumes, we derive constraints on the UV LFs at z ∼ 7 and z ∼ 9. For a faint-end slope α = − 1.74, our most likely values for M UV * and φ* at z ∼ 7 are –19.8 ± 0.4 mag and 1.1 + 1.7 −0.7 × 10 −3 Mpc −3 , respectively. Our search results for z ∼ 9 J -dropouts set a 1 σ lower limit on M UV * of –19.6 mag assuming that φ* and α are the same as their values at slightly later times. This lower limit on M UV * is 1.4 mag fainter than our best-fit value at z ∼ 4, suggesting that the UV LF has undergone substantial evolution over this time period. No evolution is ruled out at 99% confidence from z ∼ 7 to z ∼ 6 and at 80% confidence from z ∼ 9 to z ∼ 7. We find that the mass-to-light ratio of halos evolves as ~(1 + z) −1 if we require that the observed brightening in M UV * with redshift [i.e., M UV * = (− 21.02 ± 0.09) + (0.36 ± 0.08) (z − 3.8) ] be consistent with the expected evolution in the halo mass function. Finally, we consider the shape of the UV LF at z ≳ 5 and discuss the implications of the Schechter-like form of the observed LFs, particularly the unexpected abrupt cutoff at the bright end.

“Of these supernovae, only ∼ 40% of the high-redshift supernovae identified by Riess et al. (2004) and Strolger et al. (2004) appear to be well enough separated from their host galaxies to be identified as a separate source.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
