We propose to carry out spatially-resolved chemodynamical studies of starbursting dwarf galaxies by means of integral-field (IFU) spectroscopy from modern instrumentation (MUSE, WEAVE, KMOS). In this project the student will make use of IFU observations for dwarfs at different cosmic epochs (0 < z < 2) to investigate their gas-phase kinematics, metallicities and star formation histories. These observations will be compared to predictions from numerical simulations of galaxy formation to help constrain models of stellar feedback. The developed skills in the analysis of IFU data will be further used to interpret simulated ELT/HARMONI observations of high redshift dwarfs, therefore preparing the student for the scientific exploitation of next-generation IFU instruments and facilities.

我们建议利用现代仪器(MUSE、WEAVE、KMOS)的积分场(IFU)光谱对恒星爆发的矮星系进行空间分辨化学动力学研究。在这个项目中，学生将利用IFU对不同宇宙时期(0&lt；z&lt；2)矮星的观测来研究它们的气相运动学、金属性和恒星形成历史。这些观测将与星系形成的数值模拟预测进行比较，以帮助约束恒星反馈模型。发展的IFU数据分析技能将进一步用于解释高红移矮星的ELT/Harmoni模拟观测，从而使学生为科学开发下一代IFU仪器和设施做好准备。
