Collaborative Research: ACES Galactic Center Mass Flow

合作研究:ACES 银河中心质量流

基本信息

项目摘要

The center of our Milky Way Galaxy is dynamic, with stars forming in clouds of molecular gas. The pressure on the flow of gas regulates the star formation process. As gas moves in and out of galaxy centers, the galaxies grow and change. Gas flows form new stars, feed the central supermassive black hole, and eject mass in energetic outflows. The Milky Way center is the nearest and best laboratory for studying the life cycle of gas flows. The team of investigators will make the first high resolution maps of gas across the entire Milky Way center. By simultaneously mapping the gas motions and the distribution of star formation, the team will reveal how these processes are connected. This will be a significant advance in our understanding of the physics that drive the activity cycle in all galaxy centers. In addition, this work will support the creation of a program to support underrepresented students in the transition year between undergraduate and graduate school. Students will be integrated into this research collaboration and will receive data analysis training and targeted mentoring.A key research area in the National Academy’s “Pathways to Discovery in Astronomy and Astrophysics for the 2020s” report is the study of cosmic mass flows on large and small scales. The center region of the Milky Way, called the Central Molecular Zone (CMZ) is a unique ecosystem for these studies. The CMZ is the only location where gas flows from kilo-parsec scales down to proto-stellar disks can be explored simultaneously. The team will lead critical parts of the ALMA CMZ Exploration Survey (ACES), an ALMA large program to survey the entire Milky Way center and will make the first comprehensive measurement of mass flows in a galaxy nucleus. This program represents an unprecedented combination of a large observing area with high-resolution imaging. The investigators will conduct a complete census of the mass in molecular gas and protostars spanning four orders of magnitude in size scale and characterize the associated gas kinematics with more than a dozen molecular tracers. Products of this work will include a catalog of extended (diffuse) and compact (dense) mass components in the CMZ, as well as a complete kinematic model of gas motions through the CMZ. Ultimately, this project will make the definitive measurements of the rates of inflow, outflow, star formation, and accretion toward the central supermassive black hole.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
我们银河系的中心是动态的,在分子气云中形成恒星。气体流动的压力调节恒星形成过程。随着气体进出星系中心,星系的生长和变化。气流形成新的恒星,喂食中央超级黑洞,并在能量出口中排出质量。银河系中心是研究气体生命周期的最接近和最佳实验室。调查人员团队将在整个银河系中心制作第一台高分辨率地图。通过简单地映射气体运动和恒星形成的分布,团队将揭示这些过程如何连接。这将是我们对驱动所有星系中心活动周期物理学的理解的重大进步。此外,这项工作将支持创建一个计划,以支持本科和研究生院之间过渡年份中代表性不足的学生。学生将被整合到这项研究合作中,并将接受数据分析培训和针对性的心理。银河系的中心区域称为中央分子区(CMZ)是这些研究的独特生态系统。 CMZ是唯一可以简单地探索气体从千帕尔萨克缩放到原始磁盘的唯一位置。该团队将领导Alma CMZ勘探调查(ACE)的关键部分,这是一个ALMA大型计划,可调查整个银河系中心,并将首次全面测量银河系核us的质量流量。该程序代表了具有高分辨率成像的大观测区域的前所未有的组合。研究人员将在分子气体和质子中进行质量的完整人口普查,这些质量尺寸尺寸的四个数量级,并表征了具有超过十几个分子示踪剂的相关气体运动学。这项工作的产品将包括CMZ中的扩展(扩散)和紧凑(密集)质量成分的目录,以及通过CMZ的完全运动学模型。最终,该项目将对中央超级大质量黑洞的流入,出口,星形形成和积聚的速度进行确定的测量。该奖项反映了NSF的法定任务,并通过使用基金会的知识分子优点和更广泛的影响标准来评估NSF的法定任务。
