Velocities of OMC-1 flows

DOI

Observations are reported of H_2_ IR emission in the S(1) v=1-0 line at 2.121{mu}m in the Orion Molecular Cloud, OMC1, using the GriF instrument on the Canada-France-Hawaii Telescope. GriF uses a combination of adaptive optics and Fabry-Perot interferometry, yielding a spatial resolution of 0.15" to 0.18" and velocity discrimination as high as 1km/s. 193 bright H_2_ emission regions can be identified in OMC1. The general characteristics of these features are described in terms of radial velocities, brightness and spatial displacement of maxima of velocity and brightness, the latter to yield the orientation of flows in the plane of the sky. Strong spatial correlation between velocity and bright H_2_ emission is found and serves to identify many features as shocks.
