Modeling Mid-Infrared Diagnostics of Obscured Quasars and Starbursts
(IOP Publishing, 2013)
We analyze the link between active galactic nuclei (AGNs) and mid-infrared flux using dust radiative transfer calculations of starbursts realized in hydrodynamical simulations. Focusing on the effects of galaxy dust, we ...
Modeling the Dust Properties of z ~ 6 Quasars with ART2—All-Wavelength Radiative Transfer with Adaptive Refinement Tree
(IOP Publishing, 2008)
The detection of large quantities of dust in z ~ 6 quasars by infrared and radio surveys presents puzzles for the formation and evolution of dust in these early systems. Previously, Li et al. showed that luminous quasars ...
The Luminosity Dependence of Quasar Clustering
(American Astronomical Society, 2005)
We investigate the luminosity dependence of quasar clustering, inspired by numerical simulations of galaxy mergers that incorporate black hole growth. These simulations have motivated a new interpretation of the quasar ...
The Relation between Quasar and Merging Galaxy Luminosity Functions and the Merger‐driven Star Formation History of the Universe
(American Astronomical Society, 2006)
Using a model for the self-regulated growth of supermassive BHs in mergers involving gas-rich galaxies, we study the relationship between quasars and the population of merging galaxies and predict the merger-driven SFR ...
The Star Formation Rate-Dense Gas Relation in the Nuclei of Nearby Galaxies
(American Astronomical Society, 2008-07-10)
We investigate the relationship between the star formation rate (SFR) and dense molecular gas mass in the nuclei of galaxies. To do this, we utilize the observed 850 mu m luminosity as a proxy for the infrared luminosity ...
Orbital Structure of Merger Remnants. I. Effect of Gas Fraction in Pure Disk Mergers
(American Astronomical Society, 2010)
Since the violent relaxation in hierarchical merging is incomplete, elliptical galaxies retain a wealth of information about their formation pathways in their present-day orbital structure. Recent advances in integral field ...
Black Holes in Galaxy Mergers: Evolution of Quasars
(American Astronomical Society, 2005)
Based on numerical simulations of gas- rich galaxy mergers, we discuss amodel in which quasar activity is tied to the self- regulated growth of supermassive black holes in galaxies. The nuclear inflow of gas attending a ...
The Co‐Formation of Spheroids and Quasars Traced in their Clustering
(American Astronomical Society, 2007)
We compare observed clustering of quasars and galaxies as a function of redshift, mass, luminosity, and color/morphology, to constrain models of quasar fueling and the co-evolution of spheroids and supermassive black holes ...
On Sizes, Kinematics, M / L Gradients, and Light Profiles of Massive Compact Galaxies at Z ∼ 2
(American Astronomical Society, 2010)
Dissipation and Extra Light in Galactic Nuclei. Iv. Evolution in the Scaling Relations of Spheroids
(American Astronomical Society, 2009)
