Welcome

The goal of our research is to map the growth of supermassive black holes over cosmic time and to understand their co-evolution with galaxies.

Research & Science Highlights

Designed the GOODS1 multiwavelength survey, a major observational project involving NASA’s three Great Observatories, the Spitzer Space Telescope, the Hubble Space...
Used Hubble to study in detail the morphologies and colors of more than 100 radio-loud AGN. Found that host galaxies are luminous ellipticals with a very narrow range in...
Established that observed AGN properties are dominated by their orientation to the line of sight. Developed from first principles a quantitative formalism to relate numbers...
Made estimates of black hole mass and studied its relation to bolometric luminosity and Eddington ratio for 10 times more AGN than previously studied. Established that...
Established through multiwavelength observations that blazars are AGN characterized by relativistic jets oriented along the line of sight. Identified the parent population as...
Explained Chandra’s unexpected detection of strong X-ray emission from a quasar jet as Compton scattering of CMB photons. Carried out a large survey of jets with...
