- Chandra Observations of Early-Type Galaxies: Examined the point source population,
predominantly low mass X-ray binaries, and diffuse gas, concentrating on luminosity
functions, spectral properties, variability, and spatial profiles. Compared low mass
X-ray binary and globular cluster populations.
- Galaxy Distribution in 2MASS: Examined gravitational quasi-equilibrium distribution
and distribution near X-ray selected clusters.
