cds-question@unistra.frgalaxiesinfrared-sourcesstar-forming-regionsinfrared-photometryWe present James Webb Space Telescope (JWST) imaging of NGC 7469 with the Near-Infrared Camera (NIRCam) and the Mid-InfraRed Instrument (MIRI). NGC 7469 is a nearby, z=0.016317, luminous infrared galaxy (LIRG) that hosts both a Seyfert Type-1.5 nucleus and a circumnuclear starburst ring with a radius of ~0.5kpc. The new near-infrared (NIR) JWST imaging reveals 65 star-forming regions, 36 of which were not detected by HST observations. Nineteen of the 36 sources have very red NIR colors that indicate obscurations up to A_v_~7 and a contribution of at least 25% from hot dust emission to the 4.4{mu}m band. Their NIR colors are also consistent with young (<5Myr) stellar populations and more than half of them are coincident with the MIR emission peaks. These younger, dusty star-forming regions account for ~2% and ~10% of the total 1.5{mu}m and 4.4{mu}m luminosity of the starburst ring, respectively. The addition of these young regions confirm the age bimodality seen in the star-forming regions of the ring. Moreover, we have increased the number of young sources by a factor of four, raising the total percentage of the young population to ~40%. These results illustrate the effectiveness of JWST in identifying and characterizing previously hidden star formation in the densest star-forming environments around AGN.2023ApJ...942L..36Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/942/L36CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/942/L36https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/942/L36http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/942/L36https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/942/L36https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/942/L36http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/942/L36GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/942/L36/table1 (Source photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/942/L36/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/942/L36/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/942/L36/table1?GETtext/xml+votable180.050000true345.81461498.87372290.0055555555555555566/192831.324299464694731e-20 1.3234148326409263e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/942/L36?format=asciiInfrareddefaultJ/ApJ/942/L36/table1Source photometryrecnoRecord number assigned by the VizieR team.
