论文摘要
当今的恒星质量的大部分是在宇宙小于当前年龄的一半（即$ 1 \ Lessim Z \ Lessim 3 $）的星系中形成的。尽管这可能标志着星系演化的最关键时期之一，但目前，我们在此时期期间星系磁盘内冷分子气体和相关恒星形成的径向范围和分布都不清楚。这样的观察对于正确估计这些星系将其气体转化为恒星的效率以及解释控制这种效率的各种能量过程至关重要。长波长（即远红外 - 至拉迪奥）观察对于穿透与在这种时期驱动恒星质量组装的尘土飞扬的，红外的光明星系相关的高水平消失至关重要。在本文中，我们讨论了下一代非常大的阵列如何通过交付能力同时研究相对分布的能力来理解星系形成和进化，从而在未来的远处范围内的空间中同时研究了相对分布的分子分布分子和恒星形成。
The bulk of the present-day stellar mass was formed in galaxies when the universe was less than half its current age (i.e., $1 \lesssim z \lesssim 3$). While this likely marks one of the most critical time periods for galaxy evolution, we currently do not have a clear picture on the radial extent and distribution of cold molecular gas and associated star formation within the disks of galaxies during this epoch. Such observations are essential to properly estimate the efficiency at which such galaxies convert their gas into stars, as well as to account for the various energetic processes that govern this efficiency. Long-wavelength (i.e., far-infrared--to--radio) observations are critical to penetrate the high-levels of extinction associated with dusty, infrared-bright galaxies that are driving the stellar mass assembly at such epochs. In this article we discuss how the next-generation Very Large Array will take a transformative step in our understanding of galaxy formation and evolution by delivering the ability to simultaneously study the relative distributions molecular gas and star formation on sub-kpc scales unbiased by dust for large populations of typical galaxies in the early universe detected by future far-infrared space missions.
