Formation, Evolution and Properties of Isolated Field Elliptical Galaxies

Understand

[Abridged] We study the properties, evolution and formation mechanisms of isolated field elliptical galaxies.

• We create a mock catalogue of isolated field elliptical galaxies from the Millennium Simulation Galaxy Catalogue, and trace their merging histories.
• The formation, identity and assembly redshifts of simulated isolated and non-isolated elliptical galaxies are studied and compared.
• Observational and numerical data are used to compare age, mass, and the colour-magnitude relation.
