Effects of Self-Interaction and of an Ideal Gas in Binary Mergers of Bosonic Dark Matter Cores
Self-interaction changes the energy-mass scaling of BECDM core mergers from E proportional to minus M cubed to milder forms, altering mass retention, while an ideal gas only modifies the gravitational background without changing the bosonic scaling.
