The Co-Formation of Spheroids and Quasars Traced in their Clustering
Philip F. Hopkins, Adam Lidz, Lars Hernquist +4
We compare observed clustering of quasars and galaxies as a function of redshift, mass, luminosity, & color/morphology, to constrain models of quasar fueling and spheroid-BH co-evo…
An Evolutionary Model For Submillimeter Galaxies
Sukanya Chakrabarti, Yeshe Fenner, Lars Hernquist +2
[abridged]We calculate multi-wavelength spectral energy distributions (SEDs) (spanning optical to millimeter wavelengths) from simulations of major galaxy mergers with black hole f…
Higher Order Contributions to the 21 cm Power Spectrum
Adam Lidz, Oliver Zahn, Matthew McQuinn +3
We consider the contribution of 3rd and 4th order terms to the power spectrum of 21 cm brightness temperature fluctuations during the epoch of reionization, which arise because the…
Early Cosmological HII/HeIII Regions and Their Impact on Second-Generation Star Formation
Naoki Yoshida, S. Peng Oh, Tetsu Kitayama +1
(Abridged) We present the results of three-dimensional radiation-hydrodynamics simulations of the formation and evolution of early HII/HeIII regions around the first stars. Cooling…
The morphology of HII regions during reionization
Matthew McQuinn, Adam Lidz, Oliver Zahn +3
It is possible that the properties of HII regions during reionization depend sensitively on many poorly constrained quantities (the nature of the ionizing sources, the clumpiness o…
Formation of z ~ 6 quasars from hierarchical galaxy mergers
Yuexing Li, Lars Hernquist, Brant Robertson +8
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…
