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…
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…
How to Build an Empirical Speed Distribution for Dark Matter in the Solar Neighborhood
Tal Shpigel, Dylan Folsom, Mariangela Lisanti +3
The dark matter flux in a direct detection experiment depends on its local speed distribution. This distribution has been inferred from simulations of Milky Way-like galaxies, but…
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…
