Static Pressure of Hot Gas: Its Effect on the Gas Disks of Galaxies
Anatoly V. Zasov, Alexander V. Khoperskov
TL;DR
This paper investigates how the static pressure of hot gas in galaxy clusters influences the structure of gas disks in galaxies, explaining observed peculiarities when combined with dynamic pressure effects.
Contribution
It introduces the role of static hot gas pressure in shaping galaxy gas disks, providing a new perspective on galaxy-environment interactions.
Findings
Static pressure significantly affects gas disk density and thickness.
Combined static and dynamic pressures explain peculiar galaxy features.
Hot gas environments influence galaxy morphology.
Abstract
The static pressure of the hot gas that fills clusters and groups of galaxies can affect significantly the volume density and thickness of the gas disks in galaxies. In combination with the dynamic pressure, the static pressure allows several observed peculiarities of spiral galaxies surrounded by a hot medium to be explained.
