在多个波长的观测进行审查，以寻找证据的燃料机制在星系中，无论是核星爆和活动星系核活动。虽然动力学扰动如磁棒或潮汐相互作用在中心区域积聚气体，有时会引发核恒星爆发，这是无可争议的，但这些对活动星系核的燃料供给是必要的证据仍然很少。解释的时间尺度，反馈，和黑洞的演化进行了讨论。认为活动星系核的位相对应于星系的早型位相。
Observations at multiple wavelengths are reviewed to search for evidence for fueling mechanisms in galaxies, both for nuclear starbursts and AGN activity. Although it is undisputed that dynamical perturbations such as bars or tidal interactions accumulate gas in the central regions and sometimes trigger nuclear starbursts, the evidence remains scarce that these are necessary to fuel AGNs. Interpretations in terms of time-scales, feed-back, and black hole evolution are discussed. It is suggested that the AGN phase corresponds to the early-type phases of galaxies.
