The velocities of 6 cm recombination line emission originating near the galactic nucleus.
Abstract
The kinematics of the H II regions near the center of the galaxy are investigated with a beamwidth of 4.5 minutes of arc, and are found to have an ordered motion. Electron temperatures of the regions are evaluated as a clue to a possible mechanism of continuum radiation. It is also suggested that the mechanism may be nonthermal, i.e., supersonic motion producing line emission through collisions. Also considered is the possibility that the region may have resulted from a supernova explosion.
