cds-question@unistra.frmilky-way-galaxyextinctionWe aim to map the 3D distribution of the interstellar extinction of the Milky Way disk up to distances larger than those probed with the Gaia parallaxes alone. We apply the FEDReD algorithm to the 2MASS near-infrared photometry together with the Gaia DR2 astrometry and photometry. This algorithm uses a Bayesian deconvolution approach, based on an empirical HR-diagram representative of the local thin disk, in order to map the extinction as a function of distance for various fields of view. We analysed more than 5.6 million stars to obtain an extinction map of the entire Galactic disk within |b|<0.24{deg}. This map provides information up to 5kpc in the direction of the Galactic centre and at more than 7kpc in the direction of the anticentre. This map reveals the complete shape of structures known locally, such as the Vela complex or the split of the local arm. Furthermore our extinction map shows many large "clean bubbles" especially one in the Sagittarius-Carina complex, and four others which define a structure that we nickname the butterfly2020A&A...641A..79Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/641/A79CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/641/A79https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/641/A79http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/641/A79https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/641/A79https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/641/A79http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/641/A79GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/641/A79/listList of fits extinction mapsrecnoRecord number assigned by the VizieR team.
