Gamma-ray burst jets in supernovae

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.

Automated summary

Broad-line type Ic supernovae are characterized by fast photospheric expansion and lack of H and He absorption, suggesting they are powered or enhanced by a central engine like a magnetar or accreting black hole. There appears to be a connection between these supernovae and long-duration gamma-ray bursts, but the nature of this relationship has not been satisfactorily demystified.
