: If the satellites eventually infall into the host galaxies, the merger channel will be largely dominated by satellites with a mass ratio down to 1:10,(as these objects have 68 per cent of the total mass in satellites). |

Simulation
- 'Identikit' software (Barnes & Hibbard 2009) : merge的状态
- 星系的次并合对spin的影响不大,主并合又分两种情况[1]、
- fast rotator : 质量较小的merge,气体较多,merge之后可以重新获得气体和恒星,从而获得spin
- slow rotator: 质量较大的merge,气体少,并合消耗spin,因而最终是slow rotator
galaxy pair
- 大星系周围的非常close的satellite计数 [2]
- If the satellites eventually infall into the host galaxies, the merger channel will be largely dominated by satellites with a mass ratio down to 1:10,(as these objects have 68 per cent of the total mass in satellites).
