Description
Summary:In this paper, we present the new results of mathematical modeling of dwarf galaxy movement through the intracluster medium (ICM). Our numerical model includes self-gravity hydrodynamics equation for the gas component of the galaxy and collisionless Boltzmann equation for the stellar component. We also included important sub-grid physics: star-formation, supernova feedback, stellar wind, cooling, and heating function, and non-equilibrium chemistry to ion helium hydride. As a result of our simulation, we provide density, pressure, and temperature for destruction processes in the high-density intracluster medium.
