cds-question@unistra.fropen-star-clustersinfrared-photometryh-ii-regionsyoung-stellar-objectsWe observed the giant H II region around the NGC 3603 young stellar cluster (YC) with the five broad bands (70, 160, 250, 350, 500{mu}m) of the SPIRE and PACS instruments, on board the Herschel Space Observatory. Together with what is currently known of the stellar, atomic, molecular, and warm dust components, this additional and crucial information should allow us to better understand the details of the star-formation history in this region. The main objective of the investigation is to study, at high spatial resolution, the distribution and main physical characteristics of the cold dust. By reconstructing the temperature and density maps, we found, respectively, a mean value of 36K and log_10_N_H_=22.0+/-0.1/cm2. We carried out a photometric analysis detecting 107 point-like sources, mostly confined to the north and south of the cluster. By comparing our data with spectral energy distribution models, we found that 35 sources are well represented by young stellar objects in early evolutionary phases, from Class 0 to Class I. The Herschel detections also provided far-IR counterparts for 4 H_2_O masers and 11 objects previously known from mid-IR observations. The existence of so many embedded sources confirms the hypothesis of intense and ongoing star-formation activity in the region around NGC 3603 YC.2015ApJ...799..100Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/799/100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/139 : Herschel Observation Log (Herschel Science Centre, 2013)II/311 : WISE All-Sky Data Release (Cutri+ 2012)V/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)J/ApJ/719/1104 : Massive star forming complexes in GLIMPSE (Rahman+, 2010)J/A+A/481/345 : SED evolution in massive YSOs (Molinari+, 2008)J/ApJ/675/1319 : Infrared photometry of NGC 3603 (Harayama+, 2008)J/MNRAS/368/253 : Emission lines in M16, M20, NGC 3603 (Garcia-Rojas+, 2006)J/AJ/127/1014 : CCD UBVRIHa photometry in NGC 3603 (Sung+, 2004)J/MNRAS/327/23 : CCD UBVRI photometry of 7 open star clusters (Sagar+, 2001)J/A+A/291/943 : Protostellar cores (Ossenkopf+, 1994)http://www.asdc.asi.it/mmia/index.php?mission=herschel : ASDC Herschel archivehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/799/100https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/799/100http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/799/100https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/799/100https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/799/100http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/799/100GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/799/100/sources (Sources detected in the Nurnberger et al.
