PublicationThe Structure and Star Formation History of NGC 5461
We compute photoionization models for the giant extragalactic H II region NGC 5461 and compare their predictions to several observational constraints. Since we...

PublicationThe Structure of the Accretion Disk in the Lensed Quasar SBS 0909+532
We derive the size and temperature profile of the accretion disk of the lensed quasar SBS 0909+532 by measuring the wavelength dependence (chromaticity) of the...

PublicationThe Substellar Mass Function in σ Orionis
We combine results from imaging searches for substellar objects in the σ Orionis cluster and follow-up photometric and spectroscopic observations to derive a...
