The Impact of Type Ia Supernovae in Quiescent Galaxies: II. Energetics and Turbulence

Understand

Type Ia supernovae (SNe Ia) provide unique and important feedback in quiescent galaxies, but their impact has been underappreciated.

• In this paper, we analyze a series of high-resolution simulations to examine the energetics and turbulence of the medium under SNe Ia.
• We find that when SN remnants are resolved, their effects differ distinctly from a volumetric heating term, as is commonly assumed in unresolved simulations.
• First, the net heating is significantly higher than expected, by 30$\pm$10\% per cooling time.
