Orion-Monoceros viewed using 3D Slicer

We have created several "scenes" that load pre-created data into Slicer for easy viewing. Please choose the Orion-Monoceros dataset below, or go back to our pages on how to use Slicer.

This scene is based on ¹²CO (J=1-0) data first published as part of the milky way CO panorama by Dame, Hartmann & Thaddeus (2001; their survey number 27). Wilson et al. (2005) discussed this dataset in detail.

The Orion-Monoceros complex (projected in galactic coordinates) is revealed as a structure with very complex kinematics. Orion A (containing the Great Orion Nebula, M42; seen at the "bottom" of the scene when viewed from perspective "A") is characterized by a large velocity gradient along the galactic plane. To the north-west ("upper right") of Orion A lies Orion B, which is followed by further chaff. The Mon R2 complex lies north of Orion A. Interestingly, the velocity of Orion B and Mon R2 is more similar than the velocity of Orion A and B, though the latter pair is intuitively identified as a pair in 2D images.
