    • Dust Spectral Energy Distributions in the Era of Herschel and Planck: A Hierarchical Bayesian-Fitting Technique 

      Kelly, Brandon C.; Shetty, Rahul; Stutz, Amelia M.; Kauffmann, Jens; Goodman, Alyssa; Launhardt, Ralf (American Astronomical Society, 2012)
      We present a hierarchical Bayesian method for fitting infrared spectral energy distributions (SEDs) of dust emission to observed fluxes. Under the standard assumption of optically thin single temperature (T) sources, the ...

    • Hierarchical Structure of Magnetohydrodynamic Turbulence in Position-Position-Velocity Space 

      Burkhart, Blakesley; Lazarian, A.; Goodman, Alyssa; Rosolowsky, Erik (American Astronomical Society, 2013)
      Magnetohydrodynamic turbulence is able to create hierarchical structures in the interstellar medium (ISM) that are correlated on a wide range of scales via the energy cascade. We use hierarchical tree diagrams known as ...

    • A Simple Perspective on the Mass-Area Relationship in Molecular Clouds 

      Beaumont, Christopher N; Goodman, Alyssa; Alves, João F.; Lombardi, Marco; Román-Zúñiga, Carlos G.; Kauffmann, Jens; Lada, Charles J. (Oxford University Press, 2012)
      Despite over 30 yr of study, the mass–area relationship within and among clouds is still poorly understood both observationally and theoretically. Modern extinction data sets should have sufficient resolution and dynamic ...
