Resumen:
We present, for the first time, an optical spectroscopic data cube of
the giant star-forming region 30 Doradus, obtained with the GIRAFFE on
the VLT at Paranal Observatory. The main emission lines present in this
data cube correspond to Ha, [NII] 6548 λ and [NII] 6584 λ.
By using this data set, we found that Ha presents from simple to
multiple profiles, which suggests that different physical mechanisms act
in different ways on the excited gas in 30 Doradus. We found, at least,
three unclassified large expanding structures. These structures
correlate with peaks in the X-ray distribution. Given the excellent
signal-to-noise ratio and the large spatial coverage of this data cube,
we have studied in detail the kinematics of 30 Doradus, showing the
importance of the small scale phenomena on the integrated properties of
30 Doradus
