Self-interaction bounds from cosmology constrain ultralight dark matter couplings to neutrinos, electrons, and light quarks via unavoidable quantum loop corrections.
Numerical and analytic modeling of boson star-black hole systems in the nonrelativistic limit, with Fisher analysis indicating LISA sensitivity to ultralight dark matter mass and self-coupling via gravitational wave dephasing.
