  1. The COordinated Molecular Probe Line Extinction Thermal Emission Survey COMPLETE Alyssa A. Goodman, Principal Investigator (CfA) João Alves(ESA, Germany) Héctor Arce(Caltech) Paola Caselli (Arcetri, Italy) James DiFrancesco (HIA, Canada) Mark Heyer (UMASS/FCRAO) Doug Johnstone (HIA, Canada) Scott Schnee(CfA, PhD student) Mario Tafalla (OAN, Spain) Tom Wilson(MPIfR/SMTO)

  2. Molecular Line Map 2MASS/NICER Extinction Map of Orion Johnstone et al. 2001 Johnstone et al. 2001 Nagahama et al. 1998 13CO (1-0) Survey Current, Un-coordinated, State of Affairs Lombardi & Alves 2001

  3. Optical Image C18O Dust Emission Radial Density Profile, with Critical Bonnor-Ebert Sphere Fit NICER Extinction Map The Rewards of Coordination Coordinated Molecular-Probe Line, Extinction & Thermal Emission Observations of Barnard 68 This figure highlights the work of Senior Collaborator João Alves and his collaborators. The top left panel shows a deep VLT image (Alves, Lada & Lada 2001). The middle top panel shows the 850 m continuum emission (Visser, Richer & Chandler 2001) from the dust causing the extinction seen optically. The top right panel highlights the extreme depletion seen at high extinctions in C18O emission (Lada et al. 2001). The inset on the bottom right panel shows the extinction map derived from applying the NICER method applied to NTT near-infrared observations of the most extinguished portion of B68. The graph in the bottom right panel shows the incredible radial-density profile derived from the NICER extinction map (Alves, Lada & Lada 2001). Notice that the fit to this profile shows the inner portion of B68 to be essentially a perfect critical Bonner-Ebert sphere

  4. 5 degrees (~tens of pc) SIRTF Legacy Coverage of Perseus COMPLETE, Part 1 Observations: 2002-- NICER/2MASS Extinction Mapping: dust column density maps ~5 degrees mapped with ~5' resolution 2002-- FCRAO/SEQUOIA 12CO and 13CO Observations: gas temperature, density and velocity information ~40" resolution on all AV>1(COMPLETE Awarded Key Project Status, 10/02) 2003-- SCUBA Observations: dust column density maps, finds all "cold" source ~20" resolution on all AV>6 mag (COMPLETE Awarded Time, 12/10/02) c2d 2003--Mid- and Far-IR SIRTF c2d Legacy Observations: dust temperature and column density maps ~5 degrees mapped with ~15" resolution (70 m + NICER on point source distribution) Science: • Combined Thermal Emission data: dust spectral-energy distributions, giving emissivity, Tdust and Ndust • Extinction/Thermal Emission inter-comparison: unprecedented constraints on dust properties and cloud distances, in addition to high-dynamic range Ndust map • Spectral-line/Ndust Comparisons Systematic censes of inflow, outflow & turbulent motions enabled • CO maps in conjunction with SIRTF point sources will comprise YSOoutflow census

  5. FCRAO N2H+ map with CS spectra superimposed. COMPLETE, Part 2(2003-5) (Lee, Myers & Tafalla 2001). Observations, using target list generated from Part 1: NICER/8-m/IR camera OIR Observations: best density profiles for dust associated with "cores". ~10" resolution FCRAO + IRAM N2H+ Observations: gas temperature, density and velocity information for "cores”~15" resolution, ongoing beginning 2002 Science: Multiplicity/fragmentation studies Detailed modeling of pressure structure on <0.3 pc scales Searches for the "loss" of turbulent energy (coherence)

  6. Is this Really Possible Now? 1 day for a 13CO map then 1 minute for a 13CO map now

  7. Pilot COMPLETE Observations in Perseus,Spring 2002

  8. The action of multiple outflows in NGC 1333? SCUBA 850 mm Image shows Ndust(Sandell & Knee 2001) Dotted lines show CO outflow orientations (Knee & Sandell 2000)

  9. Perseus according to IRAS (warm dust!)

  10. COMPLETE: SCUBA >10 mag AV ~100 hours at SCUBA 10 pc 8 6 4 2 10 pc Ophiuchus Perseus Johnstone, Goodman & the COMPLETE team, SCUBA 2003(?!)

  11. 2 pc COMPLETE SCUBA-Prep led toDiscovery of a Heated Dust Ring in Ophiuchus Goodman, Li & Schnee 2003

  12. 2 pc …and the famous “1RXS J162554.5-233037” is right in the Middle !?

  13. The “COMPLETE” + c2d Truth about Star Formation, c. 2005 Statistical Evaluation of Outflows’ Role Evaluation of Constructive/Destructive Role of Explosions/Winds Tracking down progeny (includes USNO-B work) All data to NVO
