论文摘要
恒星形成是塑造星系的主要过程之一，定义了其出色的种群以及金属性的产生和富集。如今，已知该过程由连接三个参数的一组关系统治：分子气体质量，恒星质量和恒星形成率本身。从星系宽到KPC尺度的星系中，这些关系在各种尺度上实现。在哪个尺度上，它们被打破了，它们的通用程度（即，如果它们以不同的尺度或不同的星系类型更改），这仍然是一个开放的问题。我们在这里探讨了这些关系如何使用AS代理使用积分场谱数据和CO观察数据进行的新分析与Edge-Califa调查和Amussing ++汇编进行比较。
Star-formation is one of the main processes that shape galaxies, defining its stellar population and metallicity production and enrichment. It is nowadays known that this process is ruled by a set of relations that connect three parameters: the molecular gas mass, the stellar mass and the star-formation rate itself. These relations are fulfilled at a wide range of scales in galaxies, from galaxy wide to kpc-scales. At which scales they are broken, and how universal they are (i.e., if they change at different scales or for different galaxy types) it is still an open question. We explore here how those relations compare at different scales using as proxy the new analysis done using Integral Field Spectroscopy data and CO observations data from the EDGE-CALIFA survey and the AMUSSING++ compilation.
