We use data from the Galaxy And Mass Assembly (GAMA) survey and the Kilo-Degree Survey (KiDS). We derive redshift distributions in bins of apparent magnitude to the limits of the GAMA- KiDS photometric catalogue: m_r_ <= 23; more than a decade in luminosity beyond the limits of the GAMA spectroscopic redshift sample via clustering-based redshift inference. This technique uses spatial cross-correlation statistics for a reference set with known redshifts (in our case, the main GAMA sample) to derive the redshift distribution for the target ensemble. For the calibration of the redshift distribution, we use a simple parametrization with an adaptive normalization factor over the interval 0.005 < z < 0.48 to derive the clustering redshift results. We find that the GLF has a relatively constant power-law slope {alpha} =~ -1.2 for -17 <= M_r_ <= -13, and then appears to steepen sharply for -13 <= M_r_ <= -10. This upturn appears to be where globular clusters (GCs) take over to dominate the source counts as a function of luminosity. Thus, we have mapped the GLF across the full range of the z ~ 0 field galaxy population from the most luminous galaxies down to the GC scale.2022MNRAS.509.5467Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/509/5467CatalogResearchIsServedByTAP VizieR generic servicerelated-tohttps://kids.strw.leidenuniv.nl/DR4/ : KiDS DR4https://www.gama-survey.org/ : GAMA home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/509/5467https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/509/5467http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/509/5467https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/509/5467https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/509/5467http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/509/5467GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/509/5467/glfDensity distribution of the galaxy luminosity function at z <0.1recnoRecord number assigned by the VizieR team.
