We review the current observational status and theoretical interpretations for the class of broad lines type Ic supernovae. They are characterized by fast photospheric expansion and lack of H and He absorption. They have a larger than normal energy budget, suggesting that they are powered or, at least, augmented by a central engine, like a magnetar or an accreting black hole. There appears therefore to be a link between these supernovae and long-duration gamma-ray bursts. However, its nature has not been satisfactorily demystified.

超新星中的伽马射线爆射流

我们回顾了Ic型超新星宽线类的当前观测状态和理论解释。它们的特征是快速的光球膨胀和缺乏H和He吸收。它们具有比正常能源预算更大的能量，这表明它们是由动力或至少由中央发动机（例如磁星或积聚的黑洞）来增强的。因此，这些超新星与持续时间的伽马射线爆发之间似乎存在联系。但是，它的本质尚未令人满意地被揭开神秘面纱。
