Project A3 studies the properties of the star-forming-active interstellar medium in nearby galaxies, where the spatial resolution and/or the known morphology and kinematical structure allow resolving the (AGN or starburst) core and disk structure as well as individual regions of star forming activity. By combining the study of these different environments, observed in the major submm and FIR cooling lines and dedicated chemical species, we will explore star forming activity as a function of the UV-field, gas density and metallicity in a systematic way, supported by the appropriate excitation-, shock- and PDR-modelling.

A3项目研究附近星系中恒星形成活跃星际介质的特性，其中空间分辨率和/或已知的形态和运动学结构允许解析（AGN或星暴）核心和盘结构以及恒星形成活动的单个区域。通过结合对这些不同环境的研究，在主要的submm和FIR冷却线和专用化学物质中观察到，我们将以系统的方式探索恒星形成活动作为紫外线场，气体密度和金属丰度的函数，并辅以适当的激发，冲击和pdr模型。
