Ultra-light dark matter in disk galaxies
Nitsan Bar, Kfir Blum, Joshua Eby +1
Analytic arguments and numerical simulations show that bosonic ultra-light dark matter (ULDM) would form cored density distributions (`solitons') at the center of galaxies. ULDM so…
Stability of Condensed Fuzzy Dark Matter Halos
Joshua Eby, Madelyn Leembruggen, Peter Suranyi +1
Stability properties of gravitationally bound condensates composed of ultralight axionic Fuzzy Dark Matter (FDM) are studied. Previous work has shown that astrophysical collisions…
Collisions of Dark Matter Axion Stars with Astrophysical Sources
Joshua Eby, Madelyn Leembruggen, Joseph Leeney +2
If QCD axions form a large fraction of the total mass of dark matter, then axion stars could be very abundant in galaxies. As a result, collisions with each other, and with other a…
Collapse of Axion Stars
Joshua Eby, Madelyn Leembruggen, Peter Suranyi +1
Axion stars, gravitationally bound states of low-energy axion particles, have a maximum mass allowed by gravitational stability. Weakly bound states obtaining this maximum mass hav…
