Research

My general area of interest concerns the physics of emission line regions. My primary tool of choice is the astrophysical code known as Cloudy. Below I outline specific projects in which I am involved and our current research group at Elon University. For further details, please see my publications page.

Current Research Group:

Active Galactic Nuclei

Spatially resolving the narrow line region (NLR) of active galactic nuclei (AGN) is difficult. A novel statistical technique known as mean field individual component analysis (MFICA) can identify discrete spectral components of narrow line emitting galaxies that allow one to extract physically meaningful parameters. Plasma simulations covering a wide range of physical conditions provide the key link to understanding the deeper nature of the NLR by reproducing the spectra identified by MFICA

The evolutionary link between AGN and star formation remains a question of considerable interest. Observations of nearby starburst, star forming, and AGN galaxies can provide crucial clues about the similarities and differences of these objects. Plasma simulations can provide insight about the history of local galaxies by predicting the physical evolution of the gas within them.






Supernova Remnants

The Crab Nebula is a nearby, young supernova remnant. Despite detailed observations covering all wavelengths, many problems remain scandalously unsolved. In particular, the nature of molecular gas and the mass distribution of the Crab Nebula can be elucidated through simulations of high energy plasmas.

My research focuses on interactive learning and gender differences in introductory level physics and astronomy courses. Characterizing the gender gap in these courses will enable teachers to tailor interactive learning to maximize the potential of all students. Much of this research was made possible by the FAST Fellowship.
