Axion Minicluster Halo Limits from Wide Binary Disruption
Zihang Wang, Yu Gao
Axionic dark matter can form miniclusters and minicluster halos from inhomogenuities in the early Universe. If MCHs are sufficiently massive, their existence can be revealed by sma…

Wide Binary Evaporation by Dark Solitons: Implications from the GAIA Catalog
Qiming Qiu, Yu Gao, Haijun Tian +3
An analytic calculation is given for binary star evaporation under the tidal perturbation from randomly distributed, spatially extended dark objects. In particular, the Milky Way's…
