On the Onset of Stochasticity in CDM Cosmological Simulations
Jerome Thiebaut, Christophe Pichon, Thierry Sousbie +2
The onset of stochasticity is measured in CDM cosmological simulations using a set of classical observables. It is quantified as the local derivative of the logarithm of the dis…
The three dimensional skeleton: tracing the filamentary structure of the universe
T. Sousbie, C. Pichon, S. Colombi +2
The skeleton formalism aims at extracting and quantifying the filamentary structure of the universe is generalized to 3D density fields; a numerical method for computating a local…
Spectral Properties of Interstellar Turbulence via Velocity Channel Analysis
Dmitri Pogosyan, Alex Lazarian
In this presentation we review the link between the statistics of intensity fluctuations in spectral line data cubes with underlying statistical properties of turbulence in the int…
Velocity statistics from spectral line data: effects of density-velocity correlations, magnetic field, and shear
Alejandro Esquivel, A. Lazarian, D. Pogosyan +1
In a previous work Lazarian and Pogosyan suggested a technique to extract velocity and density statistics, of interstellar turbulence, by means of analysing statistics of spectral…
Emissivity Statistics in Turbulent, Compressible MHD Flows and the Density-Velocity Correlation
Alex Lazarian, Dmitri Pogosyan, Enrique Vazquez-Semadeni +1
In this paper we test the results of a recent analytical study by Lazarian and Pogosyan, on the statistics of emissivity in velocity channel maps, in the case of realistic density…
Velocity Modification of HI Power Spectrum
A. Lazarian, D. Pogosyan
The distribution of atomic hydrogen in the Galactic plane is usually mapped using the Doppler shift of 21cm emission line. We calculate the emission spectrum in velocity slices of…
