UV Luminosity Functions at redshifts z~4 to z~10: 10000 Galaxies from HST Legacy Fields
R. J. Bouwens, G. D. Illingworth, P. A. Oesch +11
The remarkable HST datasets from the CANDELS, HUDF09, HUDF12, ERS, and BoRG/HIPPIES programs have allowed us to map out the evolution of the UV LF from z~10 to z~4. We have identif…
Overdensities of Y-dropout Galaxies from the Brightest-of-Reionizing Galaxies Survey: A Candidate Protocluster at Redshift z~8
M. Trenti, L. D. Bradley, M. Stiavelli +8
Theoretical and numerical modeling of dark-matter halo assembly predicts that the most luminous galaxies at high redshift are surrounded by overdensities of fainter companions. We…
UV Luminosity Functions from 132 z~7 and z~8 Lyman-Break Galaxies in the ultra-deep HUDF09 and wide-area ERS WFC3/IR Observations
R. J. Bouwens, G. D. Illingworth, P. A. Oesch +8
We identify 73 z~7 and 59 z~8 candidate galaxies in the reionization epoch, and use this large 26-29.4 AB mag sample of galaxies to derive very deep luminosity functions to <-18 AB…
The Galaxy Luminosity Function during the Reionization Epoch
M. Trenti, M. Stiavelli, R. J. Bouwens +5
The new Wide Field Camera 3/IR observations on the Hubble Ultra-Deep Field started investigating the properties of galaxies during the reionization epoch. To interpret these observ…
A candidate redshift z ~ 10 galaxy and rapid changes in that population at an age of 500 Myr
R. J. Bouwens, G. D. Illingworth, I. Labbe +9
Searches for very-high-redshift galaxies over the past decade have yielded a large sample of more than 6,000 galaxies existing just 900-2,000 million years (Myr) after the Big Bang…
Star formation rates and stellar masses of z=7-8 galaxies from IRAC observations of the WFC3/IR ERS and the HUDF field
I. Labbe, V. Gonzalez, R. J. Bouwens +9
We investigate the Spitzer/IRAC properties of 36 z~7 z-dropout galaxies and 3 z~8 Y-dropout galaxies derived from deep/wide-area WFC3/IR data of the Early Release Science, the ultr…
Ultradeep Infrared Array Camera Observations of sub-L* z~7 and z~8 Galaxies in the Hubble Ultra Deep Field: the Contribution of Low-Luminosity Galaxies to the Stellar Mass Density and Reionization
I. Labbe, V. Gonzalez, R. J. Bouwens +9
We study the Spitzer Infrared Array Camera (IRAC) mid-infrared (rest-frame optical) fluxes of 14 newly WFC3/IR-detected z=7 z_{850}-dropout galaxies and 5 z=8 Y_{105}-dropout galax…
Very blue UV-continuum slopes of low luminosity z~7 galaxies from WFC3/IR: Evidence for extremely low metallicities?
R. J. Bouwens, G. D. Illingworth, P. A. Oesch +7
We use the ultra-deep WFC3/IR data over the HUDF and the Early Release Science WFC3/IR data over the CDF-South GOODS field to quantify the broadband spectral properties of candidat…
z~7 Galaxies in the HUDF: First Epoch WFC3/IR Results
P. A. Oesch, R. J. Bouwens, G. D. Illingworth +7
We present a sample of 16 robust z~7 z-drop galaxies detected by the newly installed WFC3/IR camera on the Hubble Space Telescope. Our analysis is based on the first epoch data of…
