Galaxy Simulation with Dust Formation and Destruction

Understand

We perform smoothed particle hydrodynamics (SPH) simulations of an isolated galaxy with a new treatment for dust formation and destruction.

• To this aim, we treat dust and metal production self-consistently with star formation and supernova feedback.
• For dust, we consider a simplified model of grain size distribution by representing the entire range of grain sizes with large and small grains.
• We include dust production in stellar ejecta, dust destruction by supernova (SN) shocks, grain growth by accretion and coagulation, and grain disruption by shattering.
