Journal Article
Mollá, M., Díaz, Á. I., Cavichia, O., Gibson, B. K., Maciel, W. J., Costa, R. D. D., …Few, C. G. (2019). The time evolution of the Milky Way’s oxygen abundance gradient. Monthly notices, containing papers, abstracts of papers, and reports of the proceedings of the Society, 482(3), 3071–3088. doi:10.1093/mnras/sty2877

We study the evolution of oxygen abundance radial gradients as a function of time for the Milky Way Galaxy obtained with our Mulchem chemical evolution model. We review the recent data of abundances for different objects observed in our Galactic disc... Read More

The role of stellar radial motions in shaping galaxy surface brightness profiles (2017)
Journal Article
Ruiz-Lara, T., Few, C. G., Florido, E., Gibson, B. K., Pérez, I., & Sánchez-Blázquez, P. (2017). The role of stellar radial motions in shaping galaxy surface brightness profiles. Astronomy and Astrophysics, 608, (A126). doi:10.1051/0004-6361/201731485. ISSN 0004-6361

Aims. The physics driving features such as breaks observed in galaxy surface brightness (SB) profiles remains contentious. Here, we assess the importance of stellar radial motions in shaping their characteristics. Methods. We use the simulated Milky... Read More

The properties, origin and evolution of stellar clusters in galaxy simulations and observations (2016)
Journal Article
Adamo, A., Dobbs, C. L., Few, C. G., Calzetti, D., Dale, D. A., Elmegreen, B. G., …Lee, J. (2017). The properties, origin and evolution of stellar clusters in galaxy simulations and observations.

We investigate the properties and evolution of star particles in two simulations of isolated spiral galaxies, and two galaxies from cosmological simulations. Unlike previous numerical work, where typically each star particle represents one ‘cluster’,... Read More

Testing hydrodynamics schemes in galaxy disc simulations (2016)
Journal Article
Few, C. G., Dobbs, C., Pettitt, A., & Konstandin, L. (2016). Testing hydrodynamics schemes in galaxy disc simulations. Monthly notices, containing papers, abstracts of papers, and reports of the proceedings of the Society, 460(4), 4382-4396. https://doi.org/10.1093/mnras/stw1226

We examine how three fundamentally different numerical hydrodynamics codes follow the evolution of an isothermal galactic disc with an external spiral potential. We compare an adaptive mesh refinement code (RAMSES), a smoothed particle hydrodynamics... Read More

Origin of the metallicity distribution in the thick disc (2016)
Journal Article
Miranda, M. S., Pilkington, K., Gibson, B. K., Brook, C. B., Sánchez-Blázquez, P., Minchev, I., …Dominguez-Tenreiro, R. (2016). Origin of the metallicity distribution in the thick disc. Astronomy and Astrophysics, 587, (A10). doi:10.1051/0004-6361/201525789. ISSN 0004-6361

Using a suite of cosmological chemodynamical disc galaxy simulations, we assess how (a) radial metallicity gradients evolve with scaleheight; (b) the vertical metallicity gradients change through the thick disc; and (c) the vertical gradient of the s... Read More
