HeII Reionization and its Effect on the IGM
Matthew McQuinn, Adam Lidz, Matias Zaldarriaga +4
Observations of the intergalactic medium (IGM) suggest that quasars reionize HeII in the IGM at z ~ 3. We have run a set of 190 and 430 comoving Mpc simulations of HeII being reion…
Probing Reionization with the 21 cm-Galaxy Cross Power Spectrum
Adam Lidz, Oliver Zahn, Steven Furlanetto +3
The cross-correlation between high redshift galaxies and 21 cm emission from the high redshift intergalactic medium (IGM) promises to be an excellent probe of the Epoch of Reioniza…
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…
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…
