Is Turbulence in the Interstellar Medium Driven by Feedback or Gravity? An Observational Test
Mark R. Krumholz, Blakesley Burkhart
Galaxies' interstellar media (ISM) are observed to be supersonically-turbulent, but the ultimate power source that drives turbulent motion remains uncertain. The two dominant model…
Principal Component Analysis studies of turbulence in optically thick gas
Caio Correia, Alex Lazarian, Blakesley Burkhart +2
In this work we investigate the Principal Component Analysis (PCA) sensitivity to the velocity power spectrum in high opacity regimes of the interstellar medium (ISM). For our anal…
The Phase Coherence of Interstellar Density Fluctuations
Blakesley Burkhart, Alex Lazarian
Studies of MHD turbulence often investigate the Fourier power spectrum to provide information on the nature of the turbulence cascade. However, the Fourier power spectrum only cont…
The Lognormal Probability Distribution Function of the Perseus Molecular Cloud: A Comparison of HI and Dust
Blakesley Burkhart, Min-Young Lee, Claire Murray +1
The shape of the probability distribution function (PDF) of molecular clouds is an important ingredient for modern theories of star formation and turbulence. Recently, several stud…
The Turbulence Velocity Power Spectrum of Neutral Hydrogen in the Small Magellanic Cloud
Alexey Chepurnov, Blakesley Burkhart, Alex Lazarian +1
We present the results of the Velocity Coordinate Spectrum (VCS) technique to calculate the velocity power spectrum of turbulence in the Small Magellanic Cloud (SMC) in 21cm emissi…
Observational Diagnostics of Self-Gravitating MHD Turbulence in Giant Molecular Clouds
Blakesley Burkhart, David C. Collins, Alex Lazarian
We study the observable signatures of self-gravitating MHD turbulence by applying the probability density functions (PDFs) and the spatial density power spectrum to synthetic colum…
