The Lumina Project: Morphology of Ionized Bubbles and Neutral Islands

Meredith Neyer, Aaron Smith, Ali Sadain +10

The Epoch of Reionization is characterized by the nucleation, expansion, and percolation of ionized bubbles in the intergalactic medium. Interpreting emerging multi-wavelength obse…

The THESAN-ZOOM project: clumpiness of high-redshift galaxies and its connection to bursty star formation

Zihao Wang, Xuejian Shen, Rahul Kannan +12

Recent JWST observations have revealed diverse high-redshift galaxy morphologies, including a population with irregular and clumpy structures. The physical origin of these structur…

The Thesan-Zoom project: bursty star formation is incompatible with prolonged dust survival

Enrico Garaldi, Filip Popovic, Rahul Kannan +11

Cosmic dust is a key regulator of galaxy evolution, but its build-up and survival in the first billion years remain poorly constrained. We present a systematic analysis of dust in…

Strong Stellar Diffusion from Wave DM Cosmological Simulation and Potential Unified Origin for dSphs, UFGs, and UDGs

A. Pozo, T. Broadhurst, J. Zhang +6

Our DM simulations predict that stars diffuse throughout dark matter halos over the Hubble time through a random walk driven by the wave perturbations intrinsic to DM. The re…

The Lumina Project: Intergalactic Clumping and Recombination Sinks

Ali Sadain, Aaron Smith, Oliver Zier +10

Recombinations during the Epoch of Reionization are intrinsically inhomogeneous, with different regions of the intergalactic medium contributing unevenly depending on their density…

The Lumina Project: The Demographics of Active Galactic Nuclei from Quasars to Little Red Dots at

Xuejian Shen, Oliver Zier, Aaron Smith +16

High-redshift active galactic nuclei (AGN) serve as powerful probes of early black-hole growth, galaxy formation, and the evolving intergalactic medium (IGM). In this work, we use…
