An Improved Fit to the Density Distribution in Supersonic Isothermal Turbulence
Evan Scannapieco, Marcus Brüggen, Philipp Grete +1
The density distribution of supersonic isothermal turbulence plays a critical role in many astrophysical systems. It is commonly approximated by a lognormal distribution with a var…
The Density Distribution of Compressively-Forced Supersonic Turbulence Depends on the Driving Correlation Time
Philipp Grete, Evan Scannapieco, Marcus Brüggen +1
Supersonic turbulence plays a critical role in shaping astrophysical systems, from molecular clouds to the circumgalactic medium. Key properties of this turbulence include the Mach…
Ion densities of cold clouds driven by galactic outflows
Lisiyuan Yang, Neal Katz, Evan Scannapieco +1
Observations of the circumgalactic medium (CGM) often display coincident absorption from species with widely varying ionization states, providing direct evidence for complex, multi…
Magnetically assisted vorticity production in decaying acoustic turbulence
Axel Brandenburg, Evan Scannapieco
We study vorticity production in isothermal, subsonic, acoustic (nonvortical), and decaying turbulence due to the presence of magnetic fields. Using three-dimensional numerical sim…
