The Launching of Cold Clouds by Galaxy Outflows. V. The Role of Anisotropic Thermal Conduction

Abstract Motivated by observations of multiphase galaxy outflows, we explore the impact isotropic and anisotropic electron thermal conduction on evolution radiatively cooled, cold clouds embedded in hot, magnetized winds. Using adaptive-mesh refinement code AthenaPK , conduct simulations impacted supersonic transonic flows with magnetic fields initially aligned parallel perpendicular to flow direction. In cases conduction, an evaporative wind forms, stabilizing against instabilities leading a mass-loss rate that matches hydrodynamic case. cases, is more limited strongly dependent field orientation. runs fields, lines are folded back into tail, limiting but act dampen slow stretching cloud case, aids survival forming radiative near front cloud, which suppresses reduces mass loss. all has minimal acceleration cloud.
