中文摘要

尽管宇宙可能看起来是一个广袤而人烟稀少的地方,但它的动态性质意味着星系之间经常发生碰撞。这些“星系合并”中的恒星很少正面相遇,但引力的影响可能会给整个星系带来壮观的后果。计算机模拟表明,合并导致两股物质流被撕裂,由于强大的扭矩,星系的大量气体被输送到银河系中心。这些模拟导致了对大规模核恒星爆发和中央黑洞点火的预测。因此,星系合并可能是星系演化的主要驱动力之一。
英文摘要
Although the universe may seem a vast and sparsely populated place, its dynamic nature means that galaxies regularly collide. The stars in these "galaxy mergers" rarely meet each other head-on, but the effects of gravity can have spectacular consequences for the galaxy as a whole. Computer simulations show that mergers result in both streams of material being ripped away, and large quantities of the galaxies' gas being funneled towards the galactic centre as a result of strong torque forces. These simulations have led to predictions of massive nuclear starbursts and the ignition of the central black hole. Galaxy mergers may therefore be the (or one of the) main drivers of galaxy evolution.
