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....
The Nature of CO Emission From z~6 Quasars (2007)
Narayanan, Desika, Li, Yuexing, Cox, Thomas J., Hernquist, Lars, Hopkins, Philip, Chakrabarti, Sukanya, ...
We investigate the nature of CO emission from z~6 quasars by combining non-LTE radiative transfer calculations with merger-driven models of z~6 quasar formation that arise naturally in LCDM...

Photometric Properties of the Most Massive High-Redshift Galaxies (2007)
Robertson, Brant, Li, Yuexing, Cox, Thomas J., Hernquist, Lars, Hopkins, Philip F.
We calculate the observable properties of the most massive high-redshift galaxies in the hierarchical formation scenario where stellar spheroid and supermassive black hole growth are fueled by...

Formation of z ~ 6 quasars from hierarchical galaxy mergers (2006)
Li, Yuexing, Hernquist, Lars, Robertson, Brant, Cox, Thomas J., Hopkins, Philip F., Springel, Volker, ...
The discovery of luminous quasars at redshift z ~ 6 indicates the presence of supermassive black holes (SMBHs) of mass ~10^9 Msun when the Universe was less than one billion years old. This finding...

Recent observations by Ferrarese et al. (2006) and Wehner et al. (2006) reveal that a majority of galaxies contain a central massive object (CMO), either a supermassive black hole (SMBH) or a compact...
Hopkins, Philip F., Somerville, Rachel S., Hernquist, Lars, Cox, Thomas J., Robertson, Brant, Li, Yuexing
Using a model for self-regulated growth of black holes (BHs) in mergers involving gas-rich galaxies, we study the relationship between quasars and the population of merging galaxies and predict the...

(Abridged). We model gravitational instability in a wide range of isolated disk galaxies, using GADGET, a three-dimensional, smoothed particle hydrodynamics code. The model galaxies include a dark...

We model gravitational collapse leading to star formation in a wide range of isolated disk galaxies using a three-dimensional, smoothed particle hydrodynamics code. The model galaxies include a dark...
Star formation near and far (2005)
I study star formation on three different scales-molecular clouds, isolated disk galaxies, and galaxy mergers-by means of various high-resolution, three-dimensional, smoothed-particle hydrodynamics...
The stellar mass spectrum from non-isothermal gravoturbulent fragmentation (2004)
Jappsen, Anne-Katharina, Klessen, Ralf S., Larson, Richard B., Li, Yuexing, Mac Low, Mordecai-Mark
Identifying the processes that determine the initial mass function of stars (IMF) is a fundamental problem in star formation theory. One of the major uncertainties is the exact chemical state of the...
Control of Star Formation in Galaxies by Gravitational Instability (2004)
Li, Yuexing, Mac Low, Mordecai-Mark, Klessen, Ralf S.
We study gravitational instability and consequent star formation in a wide range of isolated disk galaxies, using three-dimensional, smoothed particle hydrodynamics simulations at resolution...
Formation of Globular Clusters in Galaxy Mergers (2004)
Li, Yuexing, Mac Low, Mordecai-Mark, Klessen, Ralf S.
We present a high-resolution simulation of globular cluster formation in a galaxy merger. For the first time in such a simulation, individual star clusters are directly identified and followed on...
Initial Ionization of Compressible Turbulence (2004)
Li, Yuexing, Mac Low, Mordecai-Mark, Abel, Tom
We study the effects of the initial conditions of turbulent molecular clouds on the ionization structure in newly formed H_{ii} regions, using three-dimensional, photon-conserving radiative transfer...
Gravoturbulent Star Cluster Formation (2004)
Klessen, Ralf S., Ballesteros-Paredes, Javier, Li, Yuexing, Mac Low, Mordecai-Mark
Stars form by gravoturbulent fragmentation of interstellar gas clouds. The supersonic turbulence ubiquitously observed in Galactic molecular gas generates strong density fluctuations with gravity...
