Aperture Synthesis of Neutral Hydrogen in the Galaxy M33,

Abstract

Observations of the neutral hydrogen in the galaxy M33 with resolutions of 2' and 10 km/s are described. Detailed modeling has revealed weak evidence for spiral density waves with an arm-interarm contrast of 3 to 2 and a corotation radius in the range 7' to 12'. There is substantial evidence for large-scale warping of the plane of this galaxy in its outer extremities similar to that found in M83.
