Velocity in 6 spiral galaxies
Listed in IVOA Registry (Virtual Observatory)
High resolution Fabry-Perot data of six spiral galaxies are presented.
Description
Those data extend the previous sample of spiral galaxies studied with high resolution 3-D spectroscopy to earlier morphological types. All the galaxies in the sample have available HI data at 21cm from the VLA or Westerbork.
Velocity fields are analyzed and H{alpha} rotation curves are computed and compared to HI curves. The kinematics of NGC 5055 central regions are looked at more closely. Its peculiar kinematics can be interpreted either as a bipolar outflow or as a counter-rotating disk, possibly hosting a 9+/-2x10^8^M_{sun}-compact object.

Most of the H{alpha} rotation curves present a significantly steeper inner slope than their HI counterparts. The 21cm data thus seems affected by moderate to strong beam smearing. The beam smearing has an effect at higher scale-length/beam-width than previously thought (up to 20km/s at a ratio of 8.5).
