Multiple power-law tails in the density and column-density distribution in contracting star-forming clumps
Todor V. Veltchev, Philipp Girichidis, Lyubov Marinkova +3
We present a numerical study of the evolution of power-law tails (PLTs) in the (column-)density distributions (-PDF, -PDF) in contracting star-forming clumps in primordial ga…
On the extraction of power-law parts of the probability density functions in star-forming clouds
Todor V. Veltchev, Philipp Girichidis, Sava Donkov +5
We present a new approach to extract the power-law part of a density/column-density probability density function (rho-pdf/N-pdf) in star-forming clouds. It is based on the mathemat…
Spatially associated clump populations in Rosette from CO and dust maps
Todor V. Veltchev, Volker Ossenkopf-Okada, Orlin Stanchev +3
Spatial association of clumps from different tracers turns out to be a valuable tool to determine the physical properties of molecular clouds. It provides a reliable estimate for t…
On the link between column density distribution and density scaling relation in star formation regions
Todor Veltchev, Sava Donkov, Orlin Stanchev
We present a method to derive the density scaling relation in regions of star formation or in their turbulent vicinities from straightforward binn…
Tracing the general structure of Galactic molecular clouds using Planck data: I. The Perseus region as a test case
Orlin Stanchev, Todor V. Veltchev, Jens Kauffmann +4
We present an analysis of probability distribution functions (pdfs) of column density in different zones of the star-forming region Perseus and its diffuse environment based on the…
