Suppose that dark matter is in the form of a Bose-Einstein Condensate, with a DeBroglie wavelength of ~10,000 LY. (There are some axion models of DM where the axions are in a BEC.) In this model, the wavelength of the dark matter particles is very large (e.g. spread out).
Would dark matter be captured by and accumulate in black holes and neutron stars in this model?
If the wavelength of the particles is very large, there is a low probability that a particle will be found to be located near a small object (the NS or BH). But (1) the immense gravitational field of the NS/BH should blueshift the wavelength of some particles to essentially bring those particles out of a BEC state, (2) if a very large number of particles are spread out over a large region, I would expect some particles would inevitably find themselves near enough the object to be captured, such that the capture rate should more or less average out and be similar to the capture rate of particle dark matter.
*I don't know much about Bose-Einstein Condensates, so if I am making some critical error in my thinking, please correct me.
