cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomyinfrared-sourcesOur search for the earliest stages of massive star formation turned up 12 massive pre-protocluster candidates plus a few protoclusters. For this search, we selected 47 FIR-bright IRAS sources in the outer Galaxy. We mapped regions of several square arcminutes around the IRAS source in the millimeter continuum in order to find massive cold cloud cores possibly being in a very early stage of massive star formation. Masses and densities are derived for the 128 molecular cloud cores found in the obtained maps.2005ApJS..161..361Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/161/361CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/115/81 : A CS(2-1) survey of UC HII regions (Bronfman+, 1996)J/A+AS/143/269 : 6.7GHz methanol maser emission survey (Szymczak+, 2000)J/A+A/368/845 : Arcetri Catalog of H2O maser sources.
