| Abstract: |
Multiwavelength afterglows, the lower energy counterparts of Gamma-Ray Bursts (GRB), detected so far only for the long-duration GRB variety, have allowed astronomers to estimate precisely the distance scale of these events, to study their close environments and ultimately to identify their progenitors, i.e. powerful Type Ic supernovae. Long GRBs are extragalactic, and nearly all of them have a detected host galaxy. The properties of these galaxies support the strong link between GRBs and star formation, as expected if GRBs are originated by the death of very massive stars. The most important observations which have led to this progress are here reviewed. |
