Turbulence Spectra from Doppler-broadened Spectral Lines: Tests of the Velocity Channel Analysis and Velocity Coordinate Spectrum Techniques
A. Chrupnov, A. Lazarian
Turbulent motions induce Doppler shifts of observable emission and absorption lines motivating studies of turbulence using precision spectroscopy. We provide the numerical testing…
Polarization of Dust Emission in Clumpy Molecular Clouds and Cores
T. J. Bethell, A. Chepurnov, A. Lazarian +1
Grain alignment theory has reached the stage where quantitative predictions of the degree of alignment and its variations with optical depth are possible. With the goal of studying…
Velocity coordinate spectrum: geometrical aspects of observations
A. Chepurnov, A. Lazarian
We analyze a technique of obtaining turbulence power spectrum using spectral line data along the velocity coordinate, which we refer to as Velocity Coordinate Spectrum (VCS). We fo…
Turbulence Spectra from Spectral Lines: Tests of the Velocity Channel Analysis and Velocity Coordinate Spectrum Techniques
A. Chepurnov, A. Lazarian
Turbulence is a key element of the dynamics of astrophysical fluids, including those of interstellar medium, clusters of galaxies and circumstellar regions. Turbulent motions induc…
Velocity Spectrum for HI at High Latitudes
A. Chepurnov, A. Lazarian, S. Stanimirovic +2
In this paper we present the results of the statistical analysis of high-latitude HI turbulence in the Milky Way. We have observed HI in the 21 cm line, obtained with the Arecibo L…
The galactic foreground angular spectra
A. V. Chepurnov
Galactic synchrotron and free-free foregrounds angular spectra are analytically estimated with account for interstellar turbulence and radiating process physics. Unknown parameters…
