The Turbulence Velocity Power Spectrum of Neutral Hydrogen in the Small
  Magellanic Cloud
  We present the results of the Velocity Coordinate Spectrum (VCS) technique to
calculate the velocity power spectrum of turbulence in the Small Magellanic
Cloud (SMC) in 21cm emission. We have obtained a velocity spectral index of
-3.85 and an injection scale of 2.3 kpc. The spectral index is steeper than the
Kolmogorov index which is expected for shock-dominated turbulence which is in
agreement with past works on the SMC gas dynamics. The injection scale of 2.3
kpc suggests that tidal interactions with the Large Magellanic Cloud are the
dominate driver of turbulence in this dwarf galaxy. This implies turbulence
maybe driven by multiple mechanisms in galaxies in addition to supernova
injection and that galaxy-galaxy interactions may play an important role.
