Abstract:
We present a robust measurement and analysis of the rest-frame
ultraviolet (UV) luminosity functions at z=4-8. We use deep Hubble
Space Telescope imaging over the Cosmic Assembly Near-infrared Deep
Extragalactic Legacy Survey/GOODS fields, the Hubble Ultra Deep Field,
and the Hubble Frontier Field deep parallel observations near the
Abell 2744 and MACS J0416.1-2403 clusters. The combination of these
surveys provides an effective volume of 0.6-1.2x106Mpc3 over this
epoch, allowing us to perform a robust search for faint (MUV=-18)
and bright (MUV←21) high-redshift galaxies. We select candidate
galaxies using a well-tested photometric redshift technique with
careful screening of contaminants, finding a sample of 7446 candidate
galaxies at 3.5<z<8.5, with >1000 galaxies at z∼6-8. We measure both a
stepwise luminosity function for candidate galaxies in our redshift
samples, and a Schechter function, using a Markov Chain Monte Carlo
analysis to measure robust uncertainties. At the faint end, our UV
luminosity functions agree with previous studies, yet we find a higher
abundance of UV-bright candidate galaxies at z≥6.
Description:
Our study used imaging data from a number of surveys covering both the
northern and southern fields from the Great Observatories Origins Deep
Survey (GOODS; Giavalisco et al. 2004ApJ...600L.103G 2004ApJ...600L.103G), with both the
HST and the Spitzer Space Telescope. The deepest imaging comes from
three surveys of the HUDF: the original HUDF survey (ACS; Beckwith et
al. 2006, J/AJ/132/1729), HUDF09 (PI Illingworth; e.g., Bouwens et al.
2010ApJ...709L.133B 2010ApJ...709L.133B; Oesch et al. 2010ApJ...709L..16O 2010ApJ...709L..16O) and UDF12
surveys (PI Ellis; Ellis et al. 2013ApJ...763L...7E 2013ApJ...763L...7E; Koekemoer et al.
2013ApJS..209....3K 2013ApJS..209....3K; WFC3). The majority of our candidate galaxy
sample comes from CANDELS (PIs Faber and Ferguson; Grogin et al.
2011ApJS..197...35G 2011ApJS..197...35G; Koekemoer et al. 2011ApJS..197...36K 2011ApJS..197...36K).
Finally, we complete our data set with the recently obtained deep HST
observations near the galaxy clusters Abell 2744 and MACS J0416.1-2403
from the HFF program (PI Lotz).
