Notes. aseed is the BH spin parameter at seeding; єf is the feedback coupling efficiency (Sect. 2.4); MBH,Seed is the BH mass at seeding; M*,seed is the stellar mass considered for BH seeding (Sect. 2.1); mDM is the DM particle mass; mg is the initial gas particle mass; m* is the star particle mass; εDM,εg,and ε* are the DM, gas, and stellar and BH softening length, respectively.
