We select 39 candidates using the Lyman break technique, for which the clear non-detection in optical make the extreme mid-z interlopers hypothesis unlikely. We also take benefit from z>~6 samples selected using the previous FF data sets of Abell 2744 and MACS 0416 to improve the constraints on the properties of very high redshift objects. We compute the redshift and the physical properties such emission lines properties, star formation rate, reddening, and stellar mass for all FF objects from their spectral energy distribution using templates including nebular emission lines. We study the relationship between several physical properties and confirm the trend already observed in previous surveys for evolution of star formation rate with galaxy mass and between the size and the UV luminosity of our candidates. The analysis of the evolution of the UV luminosity function with redshift seems more compatible with an evolution of density. Moreover, no robust z>=8.5 object is selected behind the cluster field and few z~9 candidates have been selected in the two previous data sets from this legacy survey, suggesting a strong evolution in the number density of galaxies between z~8 and 9. Thanks to the use of the lensing cluster, we study the evolution of the star formation rate density produced by galaxies with L>0.03 L_{star}_, and confirm the strong decrease observed between z~8 and 9.2016ApJ...820...98Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/820/98CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/500/947 : Spectroscopy and photometry in A2744 and A2537J/ApJ/762/L30 : CLASH: MCS J0416.1-2403 strong lensing analysisJ/MNRAS/443/1549 : MACSJ0416.1-2403 strong-lensing analysis (Jauzac+, 2014)J/MNRAS/444/268 : HST Frontier Fields clusters (Richard+, 2014)J/ApJ/800/18 : HST/WFC3 observations of z~7-8 galaxies in A2744J/MNRAS/452/1437 : Abell 2744 strong-lensing analysis (Jauzac+, 2015)J/ApJ/835/113 : Galaxies >~6 from the Hubble Frontier Fieldshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/820/98https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/820/98http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/820/98https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/820/98https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/820/98http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/820/98GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/820/98/table2 (6<=z<=8 Objects Selected on the Cluster Field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/820/98/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/820/98/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/820/98/table2?GETtext/xml+votable180.050000true109.389275537.72485680.005555555555555556Cone search capability for table J/ApJ/820/98/table7 (Physical Properties of all Candidates Selected in the First Three Frontier Fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/820/98/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/820/98/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/820/98/table7?GETtext/xml+votable180.050000true3.6038561-30.3819050.005555555555555556Cone search capability for table J/ApJ/820/98/table3 (z>~8 Objects Selected in the Parallel Field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/820/98/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/820/98/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/820/98/table3?GETtext/xml+votable180.050000true109.323424637.82784530.005555555555555556Cone search capability for table J/ApJ/820/98/table4 (6<=z<=8 Objects Selected in the Parallel Field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/820/98/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/820/98/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/820/98/table4?GETtext/xml+votable180.050000true109.313303737.81011380.0055555555555555566/6383 16599 34793 347963.9193497546148093e-20 2.565265938961496e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/820/98?format=asciiInfrareddefaultJ/ApJ/820/98/table26<=z<=8 Objects Selected on the Cluster FieldrecnoRecord number assigned by the VizieR team.
