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…
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…
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…
Galaxy formation with wave/fuzzy dark matter: The core-halo structure and the solitonic imprint
Alvaro Pozo, Razieh Emami, Philip Mocz +9
Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of thes…
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…
Detection of a universal core-halo transition in dwarf galaxies as predicted by Bose-Einstein dark matter
Alvaro Pozo, Tom Broadhurst, Ivan de Martino +4
The presence of large dark matter cores in dwarf galaxies has long been puzzling and many are now known to be surrounded by an extensive halo of stars. Distinctive core-halo struct…
