Observational tests and theoretical developments of hybrid MOND dark matter models
- The putative effects of dark matter are most easily explained by a collisionless fluid on cosmological scales and by Modified Newtonian Dynamics (MOND) on galactic scales. Hybrid MOND dark matter models combine the successes of dark matter on cosmological scales and those of MOND on galactic scales. An example of such a model is superfluid dark matter (SFDM) which postulates that this differing behavior with scale is caused by a single underlying substance with two phases. In this thesis, I highlight successful observational tests of SFDM regarding strong lensing and the Milky Way rotation curve. I also discuss three problems due to the double role of the aforementioned single underlying substance and show how these may be avoided. Finally, I introduce a novel Cherenkov radiation constraint for hybrid MOND dark matter models. This constraint is different from standard modified gravity Cherenkov radiation constraints because such hybrid models allow even non-relativistic objects like stars to emit Cherenkov radiation.
