Full-data Results of Hubble Frontier Fields: UV Luminosity Functions at z ∼ 6–10 and a Consistent Picture of Cosmic Reionization

We present UV luminosity functions of dropout galaxies at ##IMG## [http://ej.iop.org/images/0004-637X/854/1/73/apjaaa544ieqn1.gif] {$z\sim 6\mbox{--}10$} with the complete Hubble Frontier Fields data. We obtain a catalog of ∼450 dropout-galaxy candidates (350, 66, and 40 at ##IMG## [http://ej.iop.org/images/0004-637X/854/1/73/apjaaa544ieqn2.gif] {$z\sim 6\mbox{--}7$} , 8, and 9, respectively), with UV absolute magnitudes that reach ##IMG## [http://ej.iop.org/images/0004-637X/854/1/73/apjaaa544ieqn3.gif] {$\sim -14$} mag, ∼2 mag deeper than the Hubble Ultra Deep Field detection limits. We carefully evaluate number densities of the dropout galaxies by Monte Carlo simulations, including all lensing effects such as magnification, distortion, and multiplication of images as well as detection completeness and contamination effects in a self-consistent manner. We find that UV luminosity functions at ##IMG##
