The Lumina Project: CMB Optical Depth Fluctuations from Patchy Reionization
Aaron Smith, Oliver Zier, Rahul Kannan +8
Patchy reionization couples the ionized-bubble morphology to the underlying density field, making the CMB Thomson optical depth sensitive to both the global ionization history and…

The THESAN project: tracking the expansion and merger histories of ionized bubbles during the Epoch of Reionization
Nathan Jamieson, Aaron Smith, Meredith Neyer +7
The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we…
