河外测线巡天

Extragalactic line surveys

Sergio Martin Ruiz

摘要:

自第一次在银河系外进行分子探测以来,已经过去了40年。从那时起,我们对银河系外ISM分子物质的分布,运动学和组成的了解不仅建立在一氧化碳观测的基础上,而且还建立在检测到的50多种分子物种的基础上。特别是,线测量已被证明是研究星系核化学成分的极好工具。目前毫米和亚毫米设备的瞬时带宽不断增加,这类研究受到青睐。在这里,我将总结河外分子光谱学的亮点,主要集中在最近几年发表的分子谱线调查的结果以及仍在进行的项目的目标。

英文摘要:

40 years have passed since the first molecular detection outside our Galaxy. Since then, our knowledge on the distribution, kinematics and composition of the molecular material in the extragalactic ISM has built up significantly based not only on the carbon monoxide observations but also in the more than 50 molecular species detected. In particular, line surveys have been proven to be excellent tools to study the chemical composition in the nuclei of galaxies. Such studies have been favored by the increasing instantaneous bandwidth of current mm and sub-mm facilities. Here I will summarize the highlights of extragalactic molecular spectroscopy, mostly focusing in the results from molecular line surveys published in the last few years as well as the aims of still ongoing projects.
