cds-question@unistra.frprotostarsinfrared-sourcesinfrared-photometryyoung-stellar-objectsStars are born deeply embedded in molecular clouds. In the earliest embedded phases, protostars emit the bulk of their radiation in the far-infrared wavelength range, where Herschel is perfectly suited to probe at high angular resolution and dynamic range. In the high-mass regime, the birthplaces of protostars are thought to be in the high-density structures known as infrared-dark clouds (IRDCs). While massive IRDCs are believed to have the right conditions to give rise to massive stars and clusters, the evolutionary sequence of this process is not well-characterized. As part of the Earliest Phases of Star formation (EPoS) Herschel guaranteed time key program, we isolate the embedded structures within IRDCs and other cold, massive molecular clouds. We present the full sample of 45 high-mass regions which were mapped at PACS 70, 100, and 160um and SPIRE 250, 350, and 500um. In the present paper, we characterize a population of cores which appear in the PACS bands and place them into context with their host molecular cloud and investigate their evolutionary stage.2012A&A...547A..49Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/547/A49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/639/227 : MSX IRDC candidate catalog (Simon+, 2006)J/ApJ/641/389 : Millimetric observations of IRDC cores (Rathborne+, 2006)J/ApJ/680/349 : Galactic distribution of IRDCs (Jackson+, 2008)J/ApJ/686/384 : ^12^CO, ^13^CO, C^18^O survey of IRDCs (Du+, 2008)J/MNRAS/399/1506 : IRDC cores in SCUBA Legacy Catalogue (Parsons+, 2009)J/ApJ/698/324 : Spitzer IRDCs (Ragan+, 2009)J/ApJ/715/310 : Early stages of star formation in IRDCs (Rathborne+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/547/A49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/547/A49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/547/A49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/547/A49https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/547/A49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/547/A49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/547/A49/table3 (IRDC (infrared-dark clouds) sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/547/A49/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/547/A49/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/547/A49/table3?GETtext/xml+votable180.050000true209.0204-62.22830.005555555555555556Cone search capability for table J/A+A/547/A49/tablec (Core catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/547/A49/tablec?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/547/A49/tablec?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/547/A49/tablec?GETtext/xml+votable180.050000true106.2377-12.281610.0055555555555555565/7383 6/1932 12971 13049 13051 14298 14307-14308 14402 14413 14607 14614 14670 14692 15430 15642 15690 21641 22212 23968 28900 29090-29091 29097 29100-29101 29112-29113 29118 29461 29505 29510 29512-29513 30218 30245 30256 30258 30262-30263 30266 30405 30691-30692 41682 41772 41780 418021.2415266230347566e-21 8.27688880188539e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/547/A49?format=asciiInfrareddefaultJ/A+A/547/A49/table3IRDC (infrared-dark clouds) samplerecnoRecord number assigned by the VizieR team.
