Understanding Galaxy Assembly (A01)

点击翻译按钮获取中文摘要

We study the condition and impact of star-formation in galaxies at the cosmic epoch when galaxies assembled and most stars in the universe formed. Through observations of prominent molecular and atomic spectral lines, we study the detailed structures, dynamics and conditions of the interstellar medium of distant and super-average star-forming galaxies. We also measure the gas content and distribution of representative sample of typical star-forming galaxies using deep continuum interferometric observations. We prepare observation with the novel sub-mm telescope CCAT-prime, and in particular exploit its unique capability to study the impact of environment on the star-forming activity of high-redshift galaxies.
