Abstract:
We studied the kinematic and thermal structure of the early phases of
high- mass and intermediate mass star formation using ammonia
observations from the Very Large Array (VLA) and the Effelsberg 100m
telescope.
Description:
We show NH3(1,1) and NH3(2,2) data cubes of VLA observations and if
possible combined with Effelsberg 100m data to compensate for missing
flux.
