  1. What is the True Distribution of Star-Forming Material in Molecular Clouds?Alyssa A. Goodman(with N. Ridge & S. Schnee)

  2. What is the True Distribution of Star-Forming Material in Molecular Clouds?MHD Turbulence Theory: lognormal(very robust result) E. Ostriker, J. Stone & C. Gammie 2001

  3. The COordinated Molecular Probe Line Extinction Thermal Emission Survey COMPLETE Alyssa A. Goodman, Principal Investigator (CfA) João Alves (ESO, Germany) Héctor Arce (Caltech) Paola Caselli (Arcetri, Italy) James DiFrancesco (HIA, Canada) Jonathan Foster (CfA, PhD Student) Mark Heyer (UMASS/FCRAO) Helen Kirk (HIA, Canada) Di Li (CfA) Doug Johnstone (HIA, Canada) Naomi Ridge (CfA) Scott Schnee (CfA, PhD student) Mario Tafalla (OAN, Spain) Tom Wilson (ESO, Germany)

  4. COMPLETE/IRAS Ndust COMPLETE/FCRAO W(13CO) Barnard’s Perseus

  5. Embracing the Confusion is Key to Understanding conspiracies of chemical excitation & depletion, optical depth, Tdust, Tgas, “,” can be critically misleading (especially for gullible theorists)

  6. Dust Density & Dust Temperature in Perseus Dust Temperature (25 to 45 K) (Based on 60/100 microns) Total Dust Column (0 to 15 mag AV) (Based on 60/100 microns)

  7. IRAS Ndust H H- emission,WHAM/SHASSA Surveys (see Finkbeiner 2003)

  8. IRAS Ndust H 2MASS/NICER Extinction H- emission,WHAM/SHASSA Surveys (see Finkbeiner 2003)

  9. Why “COMPLETE”? Schnee et al. 2004 Ridge et al. 2004 IRAS Column Density IRAS Temperature + = NICER Extinction Map Alves, Lombardi & Foster+ 2004

  10. Why “COMPLETE”? Schnee et al. 2004 Ridge et al. 2004 IRAS Column Density IRAS Temperature + = NICER Extinction Map Alves, Lombardi & Foster+ 2004

  11. What is the True Distribution of Star-Forming Material in Molecular Clouds?Alyssa A. Goodman(with N. Ridge & S. Schnee)

  12. Not all Measures of Column Density are Created Equal
