The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine, so a proxy like the abundance of α elements (e.g., Mg) with respect to iron, [α/Fe], is used. Here we report an unexpected b... Read More about A new stellar chemo-kinematic relation reveals the merger history of the milky way disk.

Cloud angular momentum and effective viscosity in global SPH simulations with feedback (2014)
Journal Article
Williamson, D. J., Thacker, R. J., Wurster, J., & Gibson, B. K. (2014). Cloud angular momentum and effective viscosity in global SPH simulations with feedback. Monthly notices of the Royal Astronomical Society, 442(4), 3674-3685. https://doi.org/10.1093/mnras/stu1121

We examine simulations of isolated galaxies to analyse the effects of localized feedback on the formation and evolution of molecular clouds. Feedback contributes to turbulence and the destruction of clouds, leading to a population of clouds that is y...
