The Garrod group uses a selection of computational models and tools to study and simulate the chemistry of the interstellar medium, star-forming regions, solar-system bodies, and low-temperature laboratory ices. The majority of the codes we use are developed within the group. Models we have developed include the three-phase (gas/grain-surface/ice) chemical kinetics code MAGICKAL, and the off-lattice microscopic Monte Carlo kinetics model MIMICK, which is used to simulate both interstellar and laboratory ice chemistry.
More information on Garrod Group research can be found under individual subheadings.
The above below shows simulated laboratory water-ice structure obtained using the Garrod group's MIMICK model. Water molecules are deposited from the gas-phase at room temperature onto a cold (85 K) surface. The model simulates the deposition process, as well as the chemical kinetics of surface diffusion, which determines the ultimate structure and porosity of the ice.
