cds-question@unistra.frgalaxiesphotometryultraviolet-photometryredshiftedWe study the UV luminosity functions (LFs) at z~4, 5, 6, and 7 based on the deep large-area optical images taken by the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP). On the 100 deg^2^ sky of the HSC SSP data available to date, we take enormous samples consisting of a total of 579565 dropout candidates at z~4-7 by the standard color selection technique, 358 out of which are spectroscopically confirmed by our follow-up spectroscopy and other studies. We obtain UV LFs at z~4-7 that span a very wide UV luminosity range of ~0.002-100L^*^_UV_(-26<M_UV_<-14mag) by combining LFs from our program and the ultra-deep Hubble Space Telescope legacy surveys. We derive three parameters of the best-fit Schechter function, {Phi}^*^, M_UV_, and {alpha}, of the UV LFs in the magnitude range where the active galactic nucleus (AGN) contribution is negligible, and find that and {Phi}^*^ decrease from z~4 to 7 with no significant evolution of M_UV_. Because our HSC SSP data bridge the LFs of galaxies and AGNs with great statistical accuracy, we carefully investigate the bright end of the galaxy UV LFs that are estimated by the subtraction of the AGN contribution either aided by spectroscopy or the best-fit AGN UV LFs. We find that the bright end of the galaxy UV LFs cannot be explained by the Schechter function fits at >2{sigma} significance, and require either double power-law functions or modified Schechter functions that consider a magnification bias due to gravitational lensing.2018PASJ...70S..10Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/70/S10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/70/S10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/70/S10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/70/S10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/70/S10https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/70/S10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/70/S10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/70/S10/table4 (Spectroscopically identified galaxies and AGNs in our dropout samples)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/70/S10/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/70/S10/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/70/S10/table4?GETtext/xml+votable180.050000true29.9556667-3.99590.0055555555555555565/6814 6/4096-4098 4102 4105-4106 9823 9986 10158 17677-17679 17682-17683 17685-17688 17690 17692 17694 17699-17701 17707-17709 17711 17718 18785 18787 18796-18797 19031 19033 19036-19037 21846 21849 21852-21853 21873 25597 25933 25935 25938 25946 25954-25955 25958 25964 25966 25968 26274 26281-26283 26962 26966 26969 26973 27245 27250 27307 27311 27649https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/70/S10?format=asciiUVdefaultJ/PASJ/70/S10/table4Spectroscopically identified galaxies and AGNs in our dropout samplesrecnoRecord number assigned by the VizieR team.
