Research Interests

I study the morphological and chemical structure of our Galaxy, the Milky Way, as probed by the locations and physical properties of high-mass star forming regions. I primarily use data from the Hii Region Discovery Survey (HRDS) and its successors.

The Hii Region Discovery Surveys discovered more than a thousand new sites of high-mass star formation in the Galaxy. (Image: Trey Wenger, NASA/JPL-Caltech/R. Hurt)
The Southern HII Region Discovery Survey (SHRDS) is using the Australia Telescope Compact Array to discover hundreds of new HII regions in the Southern sky. (Image: D. Smyth, CSIRO)
Kinematic distances are the only distances available to a majority of star forming regions in the Galaxy. My recent work developed a Monte Carlo method to derive kinematic distances. (Image: Wenger et al., 2018)

Outreach

Dark Skies, Bright Kids

At the University of Virginia, I was a volunteer with Dark Skies, Bright Kids, a non-profit, volunteer-run outreach program dedicated to enhancing science literacy for elementary school students in Virginia. We lead 8 to 10 week after school clubs at different regional elementary schools each semester, and we run one-off events around the community several times a year. Thanks to a grant from the Packard Foundation, we are now hosting week-long astronomy summer camps at schools across Virginia.

Code and Online Tools

Monte Carlo Kinematic Distances

In a recent work, we developed a new tool to calculate kinematic distances. These Monte Carlo kinematic distances have the advantage over "traditional" kinematic distances of including all of the uncertainties associated with the Galactic rotation model and the definition of the local standard of rest (Wenger et al., 2018).

HII Region Database

I compile all data from the WISE Catalog of Galactic HII Regions and our radio recombination line surveys into a single machine readable database. You can access that database here.
