The Environmental Effect of the CMF in the Galactic Center 50 km s-1 Molecular Cloud
Abstract
We present the statistical properties of molecular clumps in the Galactic center 50 km s-1 molecular cloud based on observations of the CS J = 1 - 0 emission line with the Nobeyama Millimeter Array. The CMF and size spectrum for the whole cloud can be described by power laws of dN/dM ∝ M-2.6 ± 0.1 and dN/dR ∝ R-5.9±0.3, respectively. The CMF observed in the interacting part with the Sgr A East steepens to dN/dM ∝ M -4.0±0.2. On the other hand, the interaction presumably truncates the size spectrum on the larger side of R ∼ 0.4 pc.
