Our research program has been underpinned by a vigorous series of secondments. 85 researchers have undertaken secondments for a period of 310 months. We have delivered 291/300 secondment months supported by the EU (97%). In addition, 18 months of secondments of research not funded by the EU have taken place.
The results of the project have been disseminated in 108 papers submitted or published in peer reviewed journals, all of which are available on the open access preprint server arXiv and in two conferences which received significant support from LACEGAL.
The main results so far are:
• An explanation of the origin of the observed decline in [O/Fe] (and [Mg/Fe]) with Galactocentric distance for high-metallicity stars ([Fe/H] > -1.1) based on a sample of halo stars selected within the Apache Point Observatory Galactic Evolution Experiment (APOGEE) fourteenth data release (DR14).
• The use of the state-of-the-art EAGLE simulation to study the oxygen abundance gradients of gas discs in galaxies at z = 0.
• The study of the evolution of assembly bias using a semi-analytical model of galaxy formation implemented in the Millennium-WMAP7 N-body simulation.
•The study of cosmic voids in the normal-branch Dvali-Gabadadze-Porrati (nDGP) braneworld models that are representative of a class of modified gravity theories where deviations from General Relativity are usually hidden by the Vainshtein screening in high-density environments.
•A study of 324 re-simulated clusters, which has investigated a range of properties of the halos that host clusters, the state of the gas in clusters and their galactic content (the Three Hundred project, which has featured in more than 20 papers, and which was supported by a LACEGAL workshop).
•The application of machine learning to decompose simulated galaxies into various components (e.g. thin disk, thick disk) to allow their stellar populations to be compared with observations.
