我们回顾了椭圆星系化学动力学模拟领域的最新进展，强调（在一个公认的偏见的方式）与我们的宇宙学N-体/SPH代码GCD+进行的工作。我们以前已经证明了几个主要的综合早期型系统的标度关系（如颜色-星等关系，L-x-T-x-[Fe/H]（x））的恢复时，采用的现象AGN加热计划与自洽处理的星星形成，超新星反馈，辐射冷却，化学富集，和恒星/X射线人口合成。在这里，我们强调来自模拟数据集中包含的完整空间信息的特性，包括恒星和日冕形态，金属丰度分布函数。和丰度梯度
We review recent developments in the field of chemodynamical simulations of elliptical galaxies, highlighting (in an admittedly biased fashion) the work conducted with our cosmological N-body/SPH code GCD+. We have demonstrated previously the recovery of several primary integrated early-type system scaling relations (e.g. colour-magnitude relation, L-x-T-x-[Fe/H](x)) when employing a phenomenological AGN heating scheme in conjunction with a self-consistent treatment of star formation, supernovae feedback, radiative cooling, chemical enrichment, and stellar/X-ray population synthesis. Here we emphasise characteristics derived from the full spatial information contained within the simulated dataset, including stellar and coronal morphologies, metallicity distribution functions. and abundance gradients.
