Generating the wide sequence of Diffuse Galaxies with de Broglie waves of Dark Matter
Jiashuo Zhang, Tom Broadhurst, Alvaro Pozo +8
Extensive Euclid satellite imaging at low surface brightness has revealed that most nearby galaxies are diffuse-looking spheroids, where the stellar radius increases monotonically…
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…
Infalling ultra-faint dwarfs as emissaries of the Axiverse
A. Pozo, T. Broadhurst, H. N. Luu +8
Recent discoveries of ultra-faint dwarf galaxies (UFDs) infalling onto the Milky Way, namely Leo K \& M at kpc, considerably strengthens the case that UFDs constitute…
Diverse dark matter haloes in Two-field Fuzzy Dark Matter
Hoang Nhan Luu, Philip Mocz, Mark Vogelsberger +8
Fuzzy dark matter (FDM) is a compelling candidate for dark matter, offering a natural explanation for the structure of diffuse low-mass haloes. However, the canonical FDM model wit…
A smooth filament origin for distant prolate galaxies seen by JWST and HST
Alvaro Pozo, Tom Broadhurst, Razieh Emami +7
The initial gravitational collapse of Dark Matter and gas forms a universal filamentary network where the first galaxies form, with shapes and sizes that depend on the choice of Da…
