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…
Deciphering the Soliton-Halo Relation in Fuzzy Dark Matter
Pin-Yu Liao, Guan-Ming Su, Hsi-Yu Schive +3
Soliton cores at the center of fuzzy dark matter (FDM) halos provide a promising way to distinguish FDM from other dark matter models. However, the relation between solitons and th…
Propagating Instability for Wave Dark Matter
Ui-Han Zhang, Tak-Pong Woo, Tzihong Chiueh
In the early Universe, large-scale flows were omnipresent, and the flow collisions produced sheets and filaments. This phenomenon occurs for both particle and wave dark matter. But…
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…
