The Interstellar Medium and Star Formation in nearby Galaxies (A03)

项目A3研究了附近星系中恒星形成活跃的星际介质的性质，在这些星系中，空间分辨率和/或已知的形态和运动学结构允许解析(活动星系核或星暴)核和盘结构以及恒星形成活动的各个区域。通过结合在主要的亚毫米和FIR冷却线上观察到的这些不同环境的研究和专用化学物种，我们将在适当的激发、激波和PDR模型的支持下，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。

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.
