Instability of supersonic cold streams feeding galaxies-II. Non-linear evolution of surface and body modes of Kelvin-Helmholtz instability
As part of our long-term campaign to understand how cold streams feed massive galaxies at high redshift, we study the Kelvin–Helmholtz instability (KHI) of a supersonic, cold, dense gas stream as it penetrates through a hot, dilute circumgalactic medium (CGM). A linear analysis (Paper I) showed that, for realistic conditions, KHI may produce non-linear perturbations to the stream during infall. Therefore, we proceed here to study the non-linear stage of KHI, still limited to a 2D slab with no...[Show more]
