An Infrared Through Radio Study of the Properties and Evolution of IRDC Clumps

ADS
arXiv

I assisted in many of the technical aspects of the paper including Bolocam and VLA data reduction.

We identify a potential evolutionary sequence among millimeter "clumps". HCO+ and N2H+ maps are used to measure the physical properties of some of these clumps.

Star-forming Region Sh 2-233IR. I. Deep Near-infrared Observations toward the Embedded Stellar Clusters

ADS
arXiv

My contributions to this paper were minor. Analysis of luminosity functions in the IRAS 05358+3543 region have identified different aged groups. The paper contributes to the picture of sequential (triggered?) star formation in the S233-235 region in Auriga.

Herschel observations of the W43 "mini-starburst"

A minor work as part of the Herschel Hi-Gal early science special issue.

The Bolocam Galactic Plane Survey IV: λ = 1.1 and 0.35 mm Dust Continuum Emission in the Galactic Center Region

ADS
arXiv

As with other Bolocam papers, I reduced the data.

We identify a number of interesting mm sources in the Galactic Center and characterize some of their properties using Bolocam and SHARC data.

The Bolocam Galactic Plane Survey. III. Characterizing Physical Properties of Massive Star-forming Regions in the Gemini OB1 Molecular Cloud

ADS
arXiv

As with the other Bolocam papers, I reduced the data. All of the analysis work was done by Miranda.

Because of Gem OB1's known distance (~2 kpc), it was possible to derive the physical properties of all of the 34 BGPS sources. NH3 temperatures and line widths were combined to measure total dust mass, density, and virial parameter. This paper is the best characterization of "typical" BGPS sources, at least for the outer galaxy.

The Bolocam Galactic Plane Survey. II. Catalog of the Image Data

ADS
arXiv

My primary contribution to this work was reducing the data from which catalogs were derived. As part of this process, I also made the noise maps that were part of the Bolocat process and did some of the by-eye verification work.

Bolocat extracted >8000 sources from the BGPS using a watershed decomposition method. Most of these sources have now been observed with the HHT in HCO+ and N2H+ to determine their velocity and kinematic distance.

The Bolocam Galactic Plane Survey: Survey Description and Data Reduction

ADS
arXiv

I wrote about half of this paper and did the majority of the work described, including writing the data pipeline and reducing all of the data. However, there was a good deal of work done on the project before I showed up on the scene.

The paper describes the methods by which we reduced the Bolocam observations of the Northern Galactic Plane and the tests we ran to determine how well we recovered the "true" sky structure.

Outflows and Massive Stars in the protocluster IRAS 05358+3543

ADS
arXiv

A mm and near-IR study of the IRAS 05358+3543 system. Recently (2011), it has become clear that "protocluster" is unlikely to be the right label for IRAS 05358+3543. "proto-association" might be more accurate.

Perhaps the most interesting result of this paper is the discovery that the central source is likely to be a 400-AU binary with two massive (>8 msun) stars at different evolutionary stages. It is just barely in ALMA's range...

A spatially resolved study of photoelectric heating and [C II] cooling in the LMC. Comparison with dust emission as seen by SAGE

ADS
arXiv

My contribution to this paper was quite minor. I was briefly a member of the SAGE team and this is the only SAGE paper I'm included on.

Kinematics and H2 morphology of the multipolar post-AGB star IRAS 16594-4656

ADS
arXiv

An interesting examination of the morphology of the circumstellar material around IRAS 16594-4656. I did this work with Toshiya Ueta at the University of Denver. My contribution was azimuthally interpolating the 7 high-resolution long-slit spectra onto a 3-dimensional grid, creating a full 3D position-velocity cube. I used the Perl Data Language, which I have since abandoned.
