Query: The spatially resolved host of GRB 060505 and implications for the
  nature of the progenitor   We present a study of the host galaxy of the Gamma-Ray Burst (GRB) of May 5
2006 (GRB 060505). The host is spatially resolved in both imaging data and in a
long slit spectrum including the GRB site. We find the galaxy to be a Sbc
spiral, which is unusual for a long GRB host galaxy. The site of the GRB is
considerably different from the rest of the galaxy with intense star formation,
low metallicity and a young age. This suggest a massive stellar progenitor
rather than a merger of compact objects which has been suggested based on the
the relatively short duration of T_90=4s for the prompt emission.
