3D spectroscopy of Wolf-Rayet HII galaxies
  Wolf-Rayet (WR) HII galaxies are local metal-poor star-forming galaxies,
observed when the most massive stars are evolving from O stars to WR stars,
making them template systems to study distant starbursts. We have been
performing a program to investigate the interplay between massive stars and gas
in WR HII galaxies using IFS. Here, we highlight some results from the first 3D
spectroscopic study of Mrk 178, the closest metal-poor WR HII galaxy, focusing
on the origin of the nebular HeII emission and the aperture effects on the
detection of WR features.
