Clumps to cores distributions in W43 complex and others

Abstract

W43 complex lies at a fairly dynamical place on the Galactic Plane: the meeting point of the Scutum-Crux Galactic arm and the bar at a distance of 6 kpc to the Sun. The global structure of atomic and molecular gas in W43 indicates that its structure is consistent with results from dynamical numerical simulations of covering flows.
The recent observations from different galactic plane surveys offer a fuller spectrum of photometric data: from 70 micron to 1.1mm. The data set allows us to separate the different populations of objects and follow them from clumps to core scales.
We aim at comparing the distributions function, mass functions at different wavelengths. We also try to characterize the special features of W43 compared to other region.
