The Challenge of Observing Patchy Reionization with CMB Optical-Depth Fluctuations

Nick Takoudes, Hanjue Zhu, Nickolay Y. Gnedin

Spatial fluctuations in the Thomson optical depth encode information about the inhomogeneous nature of cosmic reionization. We compute the optical-depth angular power spectrum, $C_…

The Last Crossing in Excursion-Set Theory of Cosmic Reionization

Hanjue Zhu

I introduce the last crossing of the photon-counting barrier as a statistic for analytical models of cosmic reionization. Because ionizing galaxies are biased tracers of density an…

Damping Wing-Like Features in the Spectra of High Redshift Quasars: a Challenge for Fully-Coupled Simulations

Nickolay Y. Gnedin, Hanjue Zhu

Recently, several observational detections of damping-wing-like features at the edges of ``dark gaps" in the spectra of distant quasars (the ``Malloy-Lidz effect") have been report…

Cosmic Ray Mediated Thermal Fronts in the Warm-Hot Circumgalactic Medium

Hanjue Zhu, Ellen G. Zweibel, Nickolay Y. Gnedin

We investigate the 1D plane-parallel front connecting the warm ( K) and hot ( K) phases of the circumgalactic medium (CGM), focusing on the influence of cosmic rays (CR…

On the Physical Nature of Ly Transmission Spikes in High Redshift Quasar Spectra

Hanjue Zhu, Nickolay Gnedin, Camille Avestruz

We investigate Lyman-alpha (Ly) transmission spikes at using synthetic quasar spectra from the ``Cosmic Reionization On Computers" simulations. We focus on under…

Mass-Metallicity Relation during the Epoch of Reionization in the CROC Simulations

Isaac Noel, Hanjue Zhu, Nickolay Gnedin

The low-redshift mass-metallicity relation (MZR) is well studied, but the high-redshift MZR remains difficult to observe. To study the early MZR further, we analyze the Cosmic Reio…
