My main research interest is star formation in nearby galaxies. For my thesis work, I studied star formation in a sample of 20 bulgeless disk galaxies. My collaborators and I have recently completed a paper on this topic:

"Properties of Bulgeless Disk Galaxies II. Star Formation as a Function of Circular Velocity" -- Watson et al. (2012) (ADS link). Here's a brief video that highlights the main results.

As part of my thesis, I also studied the atomic gas properties of bulgeless disk galaxies. For this study, I used HI 21 cm emission line data from the Very Large Array. If you click on the image of NGC 2805 above, you'll be taken to a movie showing the HI emission from this galaxy as a function of frequency. This paper describes our study: "Properties of Bulgeless Disk Galaxies: I. Atomic Gas" -- Watson et al. (2011) (ADS link)

I am also interested in the location of active galactic nuclei (AGNs) on the M - σ relation, the correlation between the mass of the central black hole in a galaxy (M) and the stellar velocity dispersion of the host spheroid (σ). These two papers describe my work in this area:

"First Stellar Velocity Dispersion Measurement of a Luminous Quasar Host with Gemini North Laser Guide Star Adaptive Optics" -- Watson et al. (2008) (ADS link). This work is also described in the December 2008 issue of Gemini Focus -- Link to Gemini Focus

"Revisiting the Black Hole Masses of Soft X-ray Selected AGNs" -- Watson et al. (2007) (ADS link)

As an undergraduate, I worked with Fred Hamann studying the connection between black holes and their host galaxies and with Ata Sarajedini on photometry of the open cluster M67. I also spent a summer at the Center for Astrophysics working with Margarita Karovska on potential Cepheid studies that could be carried out with the Stellar Imager.
