Dust Simulations in the Distant Universe
Explore the fascinating world of dust in the distant universe through chemodynamical simulations presented by Alice Ferreira from Durham University. Discover types of dust, dust production mechanisms in core-collapse supernovae and AGB stars, grain growth in the interstellar medium, and thermal sputtering processes. Dive into the simulation of dust on a cosmological scale and uncover insights into the complex dynamics of dust in the cosmos.

Summary Modelling dust is important to explain dust masses at high redshift and more accurately correct for dust in observations We include the processes of dust production by stars, grain growth, and destruction by thermal sputtering, supernova shock waves and star formation in the ISM in our cosmological simulations We have preliminarily compared our results with observations
