摘要

。关于分子云及其与恒星形成和星系结构的关系的许多已知知识都是从大规模CO调查中获得的。然而，由于一些原因，与早期的21厘米调查相比，这些调查没有那么系统和完整;还有许多工作要做。在对已经学到的东西做一个非常简短的概括之后，我将强调目前在外星系以及高纬度和中纬度地区正在进行的工作。我也会简要介绍一下M31的进展情况。在结论中，我们将论证用专用的多馈电望远镜在角分辨率为V的情况下进行完整的银河系CO测量是非常可行的。

Molecular astrophysics: Molecular clouds in the Milky Way

. Much of what is known about molecular clouds and their rela-tion to star formation and galactic structure has been obtained from the large scale CO surveys. For several reasons, however, these have been done less systematically and less completely than the early 21 cm surveys; a great deal remains to be done. After a very brief general summary of what has been learned, I will emphasize the work now underway on the outer Galaxy and at high and intermediate latitudes. I will also briefly describe work in progress on M31. It will be argued in conclusion that a complete Galactic CO survey at an angular resolution of V is quite feasible with a dedicated multiple-feed telescope.

期刊介绍： Molecular Astrophysics is a peer-reviewed journal containing full research articles, selected review articles, and thematic issues. Molecular Astrophysics is a new journal where researchers working in planetary and exoplanetary science, astrochemistry, astrobiology, spectroscopy, physical chemistry and chemical physics can meet and exchange their ideas. Understanding the origin and evolution of interstellar and circumstellar molecules is key to understanding the Universe around us and our place in it and has become a fundamental goal of modern astrophysics. Molecular Astrophysics aims to provide a platform for scientists studying the chemical processes that form and dissociate molecules, and control chemical abundances in the universe, particularly in Solar System objects including planets, moons, and comets, in the atmospheres of exoplanets, as well as in regions of star and planet formation in the interstellar medium of galaxies. Observational studies of the molecular universe are driven by a range of new space missions and large-scale scale observatories opening up. With the Spitzer Space Telescope, the Herschel Space Observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), NASA''s Kepler mission, the Rosetta mission, and more major future facilities such as NASA''s James Webb Space Telescope and various missions to Mars, the journal taps into the expected new insights and the need to bring the various communities together on one platform. The journal aims to cover observational, laboratory as well as computational results in the galactic, extragalactic and intergalactic areas of our universe.
