TL;DR
This survey provides a detailed wide-field CO(3-2) spectral mapping of the Orion molecular cloud complex, revealing gas dynamics, structures, and star formation activity with high resolution and new insights into cloud interactions and outflows.
Contribution
First large-scale CO(3-2) survey of Orion with detailed analysis of gas dynamics, structures, and star formation indicators using the SuperCAM array on APEX.
Findings
Detection of expanding bubbles and line splitting indicating dynamic gas motions.
Identification of warm CO regions and multiple velocity components in Orion A and B.
Tracing high-velocity outflows and identifying the true driving sources of protostellar jets.
Abstract
The Orion molecular cloud complex harbours the nearest GMCs and site of high-mass star formation. Its YSO populations are thoroughly characterized. The region is therefore a prime target for the study of star formation. Here, we verify the performance of the SuperCAM 64 pixel heterodyne array on APEX. We give a descriptive overview of a set of wide-field CO(3-2) spectral cubes obtained towards the Orion GMC complex, aimed at characterizing the dynamics and structure of the extended molecular gas in diverse regions of the clouds, ranging from very active sites of clustered star formation in Orion B to comparatively quiet regions in southern Orion A. We present a 2.7 square degree (130pc) mapping survey in the CO(3-2) transition, obtained using SuperCAM on APEX at an angular resolution of 19'' (7600AU or 0.037pc at a distance of 400pc), covering L1622, NGC2071, NGC2068, OriB9,…
