cds-question@unistra.frh-ii-regionsinfrared-photometryWe present deep, wide field J, H and Ks images taken with Infrared Imager and Spectrometer 2 (IRIS2) on the Anglo-Australian Telescope, towards the massive star formation region G305.2+0.2. Combined with 3.6, 4.5, 5.8 and 8.0um data from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) survey on the Spitzer Space Telescope, we investigate the properties of the embedded stellar populations. After removing contamination from foreground stars, we separate the sources based on their infrared (IR) colour. Strong extended emission in the GLIMPSE images hampers investigation of the most embedded sources towards the known sites of massive star formation. However, we find a sizeable population of IR excess sources in the surrounding region free from these completeness effects. Investigation reveals the recent star formation activity in the region is more widespread than previously known.2007MNRAS.380.1497Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/380/1497CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.astro.wisc.edu/glimpse/glimpsedata.html : GLIMPSE Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/380/1497https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/380/1497http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/380/1497https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/380/1497https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/380/1497http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/380/1497GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/380/1497/table1 (*IRIS2-GLIMPSE catalog of sources in G305.2+0.2)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/380/1497/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/380/1497/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/380/1497/table1?GETtext/xml+votable180.050000true197.8149-62.6550.0055555555555555566/41655 41661https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/380/1497?format=asciiInfrareddefaultJ/MNRAS/380/1497/table1*IRIS2-GLIMPSE catalog of sources in G305.2+0.2recnoRecord number assigned by the VizieR team.
