cds-question@unistra.frgalaxiesgalaxy-classification-systemsspectroscopyWe present the PHANGS-MUSE/HST-H{alpha} nebulae catalogue, comprising 5177 spatially resolved nebulae across 19 nearby star-forming galaxies (D<20Mpc), based on high-resolution HST H{alpha} imaging homogenised to a fixed 10pc resolution. In synergy with PHANGS-MUSE spectroscopy, we robustly classify 4882 HII regions, derive electron densities for 2544, and provide consistent sizes, luminosities, morphologies, and emission-line diagnostics. Structural complexity is quantified via hierarchical segmentation, highlighting a large fraction of HII complexes in galactic centres. A luminosity-size relation calibrated on the HST sample is applied to 30790 MUSE nebulae, recovering sizes down to ~1pc. Cross-matching with PHANGS-HST stellar associations links 3349 nebulae to powering populations, with median ages ~3Myr and masses 10^4^-10^5^M_{sun}_. This dataset provides the largest parsec-scale resolved benchmark to date for connecting ionised nebulae, stellar populations, and ISM conditions across nearby galaxies.2026A&A...706A..95Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/706/A95CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/706/A95https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/706/A95http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/706/A95https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/706/A95https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/706/A95http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/706/A95GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/706/A95/neb_cat (Main PHANGS-MUSE/HST Halpha Nebulae Catalogu)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/706/A95/neb_cat?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/706/A95/neb_cat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/706/A95/neb_cat?GETtext/xml+votable180.050000true353.6064967576-36.11488630920.005555555555555556Cone search capability for table J/A+A/706/A95/list (List of fits maps and masks)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/706/A95/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/706/A95/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/706/A95/list?GETtext/xml+votable180.050000true325.11046-70.099990.0055555555555555566/17747 17753 18386 18398 24912 26303 27514 27728 27861 28033 28035 28167 33920-33921 33958 34343 34382 34404 34531 36134 36261 40223 40328 45448 46481 46549https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/706/A95?format=asciiOpticaldefaultJ/A+A/706/A95/neb_catMain PHANGS-MUSE/HST Halpha Nebulae CatalogurecnoRecord number assigned by the VizieR team.
