CMBPol Mission Concept Study: Reionization Science with the Cosmic Microwave Background
Matias Zaldarriaga, Loris Colombo, Eiichiro Komatsu +6
We summarize existing constraints on the epoch of reionization and discuss the observational probes that are sensitive to the process. We focus on the role large scale polarization…
Photo-heating and the fate of hard photons during the reionisation of HeII by quasars
James S. Bolton, S. Peng Oh, Steven R. Furlanetto
We use a combination of analytic and numerical arguments to consider the impact of quasar photo-heating during HeII reionisation on the thermal evolution of the intergalactic mediu…
A Global Stability Analysis of Clusters of Galaxies with Conduction and AGN Feedback Heating
Fulai Guo, S. Peng Oh, M. Ruszkowski
We investigate a series of steady-state models of galaxy clusters, in which the hot intracluster gas is efficiently heated by active galactic nucleus (AGN) feedback and thermal con…
Fossil Ionized Bubbles Around Dead Quasars During Reionization
Steven Furlanetto, Zoltan Haiman, S. Peng Oh
One of the most dramatic signatures of the reionization era may be the enormous ionized bubbles around luminous quasars (with radii reaching ~40 comoving Mpc), which may survive as…
Inhomogeneous Helium Reionization and the Equation of State of the Intergalactic Medium
Steven Furlanetto, S. Peng Oh
The temperature of the intergalactic medium (IGM) is set by the competition between photoheating and adiabatic cooling, which are usually assumed to define a tight equation of stat…
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…
