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 hot circumgalactic medium in stacked X-rays: observations vs simulations
Skylar Grayson, Evan Scannapieco, Johan Comparat +5
Current cosmological simulations rely on active galactic nuclei (AGN) feedback to quench star formation and match observed stellar mass distributions, but models for AGN feedback a…
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…
Understanding Density Fluctuations in Supersonic, Isothermal Turbulence
Evan Scannapieco, Liubin Pan, Edward Buie +1
Supersonic turbulence occurs in many environments, particularly in astrophysics. In the crucial case of isothermal turbulence, the probability density function (PDF) of the logarit…
