Structural Analysis of Molecular Clouds: Dendrograms
E. W. Rosolowsky, J. E. Pineda, J. Kauffmann +1
We demonstrate the utility of dendrograms at representing the essential features of the hierarchical structure of the isosurfaces for molecular line data cubes. The dendrogram of a…
CO Isotopologues in the Perseus Molecular Cloud Complex: the X-Factor and Regional Variations
Jaime E. Pineda, Paola Caselli, Alyssa A. Goodman
We use the COMPLETE data to derive new calibrations of the X-factor and the 13CO abundance within Perseus. We divide Perseus into six sub-regions. The standard X factor, X=N(H2)/W(…
Hunting Galaxies to (and for) Extinction
Jonathan B. Foster, Carlos Román-Zúñiga, Alyssa A. Goodman +2
In studies of star-forming regions, near-infrared excess (NIRX) sources--objects with intrinsic colors redder than normal stars--constitute both signal (young stars) and noise (e.g…
TMC-1C: an accreting starless core
S. Schnee, P. Caselli, A. Goodman +3
We have mapped the starless core TMC-1C in a variety of molecular lines with the IRAM 30m telescope. High density tracers show clear signs of self-absorption and sub-sonic infall a…
Application of Medical Imaging Software to 3D Visualization of Astronomical Data
Michelle Borkin, Alyssa Goodman, Michael Halle +1
The AstroMed project at Harvard University's Initiative in Innovative Computing (IIC) is working on improved visualization and data sharing solutions applicable to the fields of bo…
The COMPLETE Survey of Star-Forming Regions: Phase I Data
Naomi A. Ridge, James Di Francesco, Helen Kirk +14
We present an overview of data available for the Ophiuchus and Perseus molecular clouds from ``Phase I'' of the COMPLETE Survey of Star-Forming Regions. This survey provides a rang…
Estimating Column Density in Molecular Clouds with FIR and Sub-mm Emission Maps
S. Schnee, T. Bethell, A. Goodman
We have used a numerical simulation of a turbulent cloud to synthesize maps of the thermal emission from dust at a variety of far-IR and sub-mm wavelengths. The average column dens…
The COMPLETE Nature of the Warm Dust Ring in Perseus
Naomi A. Ridge, Scott L. Schnee, Alyssa A. Goodman +1
The Perseus molecular cloud complex is a ~30pc long chain of molecular clouds most well-known for the two star-forming clusters NGC1333 and IC348 and the well-studied outflow sourc…
Cloudshine: New Light on Dark Clouds
Jonathan B. Foster, Alyssa A. Goodman
We present new deep near-infrared images of dark clouds in the Perseus molecular complex. These images show beautiful extended emission which we model as scattered ambient starligh…
A COMPLETE Look at The Use of IRAS Emission Maps to Estimate Extinction and Dust Temperature
Scott L. Schnee, Naomi A. Ridge, Alyssa A. Goodman +1
We have created new dust temperature and column density maps of Perseus, Ophiuchus and Serpens using 60 and 100 micron data from the IRIS recalibration of IRAS data. We describe an…
Demonstration of the applicability of 3D Slicer to Astronomical Data Using 13CO and C18O Observations of IC348
Michelle A. Borkin, Naomi A. Ridge, Alyssa A. Goodman +1
3D Slicer, a brain imaging and visualization computer application developed at Brigham and Women's Hospital's Surgical Planning Lab, was used to visualize the IC 348 star-forming c…
Density and Temperature Structure of TMC-1C from 450 and 850 micron Maps
S. Schnee, A. Goodman
We have mapped the central 10'x10' of the dense core TMC-1C at 450 and 850 microns using SCUBA on the James Clerk Maxwell Telescope. The unusually high quality of the 450 micron ma…
The COMPLETE Survey of Star-Forming Regions on its Second Birthday
Alyssa A. Goodman
At age two, humans are just learning to speak, and they see the world in an unbiased way. At age two, the COMPLETE (COordinated Molecular Probe Line Extinction Thermal Emission) Su…
PV Ceph: Young Star Caught Speeding?
Alyssa A. Goodman, Hector G. Arce
Three independent lines of evidence imply that the young star PV Ceph is moving at roughly 20 km/s through the interstellar medium. The first, and strongest, suggestion of motion c…
The Spectral Correlation Function of Molecular Clouds: A Statistical Test for Theoretical Models
Paolo Padoan, Alyssa Goodman, Mika Juvela
We compute the spectral correlation function (SCF) of 13CO J=1--0 maps of molecular cloud complexes. The SCF is a power law over approximately an order of magnitude in spatial sepa…
