cds-question@unistra.frmolecular-cloudsradio-spectroscopyWe present a complete survey of current star formation in the Perseus molecular cloud, made at 850 and 450{mu} with SCUBA at the JCMT. Covering 3deg^2^, this submillimetre continuum survey for protostellar activity is second in size only to that of rho Ophiuchus (Johnstone et al., 2004ApJ...611L..45J). Complete above 0.4M_{sun}_ (5{sigma} detection in a 14" beam), we detect a total of 91 protostars and pre-stellar cores. Of these, 80% lie in clusters, representative of star formation across the Galaxy. Two of the groups of cores are associated with the young stellar clusters IC 348 and NGC 1333, and are consistent with a steady or reduced star formation rate in the last 0.5Myr, but not an increasing one. In Perseus, 40-60% of cores are in small clusters (<50M_{sun}_) and isolated objects, much more than the 10% suggested from infrared studies. Complementing the dust continuum, we present a C^18^O map of the whole cloud at 1' resolution.2005A&A...440..151Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/440/151CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/359/113 : X-ray and IR study of Rho Oph dark cloud (Grosso+, 2000)J/PASJ/55/653 : Chandra X-ray flares in rho Ophiuchi (Imanishi+, 2003)J/A+A/429/963 : XMM-Newton observation of the rho Oph cloud (Ozawa+, 2005)J/A+A/430/549 : C^18^O/C^17^O near rho Oph (Wouterloot+, 2005)J/ApJ/630/381 : Mid-IR imaging in {rho} Oph (Barsony+, 2005)J/A+A/447/609 : mm continuum obs. in rho Oph cloud (Stanke+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/440/151https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/440/151http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/440/151https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/440/151https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/440/151http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/440/151GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/440/151/tablea1 (SCUBA 850{mu}m core positions, names and references, peak 850{mu}m fluxes and C^18^O integrated intensity at the submm peak position)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/440/151/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/440/151/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/440/151/tablea1?GETtext/xml+votable180.050000true53.32458331.1591670.0055555555555555566/857-860 862 881 1539 1542https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/440/151?format=asciiRadiodefaultJ/A+A/440/151/tablea1SCUBA 850{mu}m core positions, names and references, peak 850{mu}m fluxes and C^18^O integrated intensity at the submm peak positionrecnoRecord number assigned by the VizieR team.
