| Description |
While bolometric images provide a ..snapshot. of the impact of
high-mass star formation over entire molecular cloud complexes, it is only by
pursuing large scale maps of different spectrally-resolved line tracers of the
ionized and the warm neutral gas that we can probe and study the cloud dynamics
and kinematics in detail.
We propose to use HIFI to carry out large scale mapping of the core of the
Orion GMC (7.5.x11.5.), the closest high-mass SFR in the disk of the galaxy.
Our goal is to study the impact and feedback
of the high-mass star formation process on the parental molecular cloud by following the
ionized, the warm neutral gas and the dense
molecular gas over large scales and at high spatial resolutions.
The global cloud dynamics, the kinematic interplay of the different gas phase components
and their influence on the environment will be revealed by a series of velocity-resolved
[NII], [CII], CH+, CH, high-J CO, HCO+ and HCN line maps
that cannot not be observed from the ground. |
