cds-question@unistra.frgalaxiesvisible-astronomyplanetary-nebulaeapparent-magnitudeNGC 253, the Sculptor galaxy, is the southern, massive, star-forming disk galaxy closest to the Milky Way. In this work, we present a new 103-pointing MUSE mosaic of this galaxy covering the majority of its star-forming disk up to 0.75xR25. With an area of ~20x5 arcmin^2^ (~20x5 kpc^2^, projected) and a physical resolution of ~15pc, this mosaic constitutes one of the largest, highest physical resolution integral field spectroscopy surveys of any star-forming galaxy to date. Here, we exploit the mosaic to identify a sample of ~500 planetary nebulae (~20 times larger than in previous studies) to build the planetary nebula luminosity function (PNLF) and obtain a new estimate of the distance to NGC 253. The value obtained is 17% higher than estimates returned by other reliable measurements, mainly obtained via the top of the red giant branch method (TRGB). The PNLF also varies between the centre (r<4 kpc) and the disk of the galaxy. The distance derived from the PNLF of the outer disk is comparable to that of the full sample, while the PNLF of the centre returns a distance ~0.9Mpc larger. Our analysis suggests that extinction related to the dust-rich interstellar medium and edge-on view of the galaxy (the average E(B-V) across the disk is ~0.35mag) plays a major role in explaining both the larger distance recovered from the full PNLF and the difference between the PNLFs in the centre and in the disk.2025A&A...700A.125Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/700/A125CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/550/A12 : NGC253 near-infrared H_2_ emission (Rosenberg+, 2013)J/A+A/562/A73 : ZJ VISTA photometry in NGC253 stellar halo (Greggio+, 2014)J/A+A/611/A21 : Globular cluster candidates in NGC253 (Cantiello+, 2018)J/ApJ/736/24 : VI photometry of sources in NGC253 halo (Bailin+, 2011)J/MNRAS/388/849 : NGC253 XMM observations (Barnard+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/700/A125https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/700/A125http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/700/A125https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/700/A125https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/700/A125http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/700/A125GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/700/A125/catalog (Position, line fluxes and [OIII] 5007 magnitudes for a PNe in NGC 253)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/700/A125/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/700/A125/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/700/A125/catalog?GETtext/xml+votable180.050000true11.9876147806523-25.22195245975790.0055555555555555566/16653 16655 16664 16666https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/700/A125?format=asciiOpticaldefaultJ/A+A/700/A125/catalogPosition, line fluxes and [OIII] 5007 magnitudes for a PNe in NGC 253recnoRecord number assigned by the VizieR team.
