The goal of this project is to study the relationship between supermassive black hole growth and galaxy evolution at the highest redshifts by carrying out detailed observations of the most distant quasars and their host galaxies using ALMA and new optical/near-IR facilities. The program will obtain deep, high resolution submillimeter continuum and [CII]/CO line observations of a complete sample of SDSS quasars at redshifts around 6 during the ALMA early science phase. These observations will reach an order magnitude deeper than current limits, and will be used to measure star formation rate, size, and gas kinematics of the host galaxies, and provide estimates of the galaxy dynamical mass. The program will also use new sensitive near-IR spectrographs on 6-10m telescopes, including Magellan, LBT and VLT, to measure supermassive black hole masses and chemical abundances in the environments of distant quasars. The observations will map the accretion and growth history of quasar central black holes, and probe the star formation and galaxy assembly history of their host galaxies.Broader impacts of the work include training of undergraduate and graduate students, and pathfinding use of ALMA in early science mode.

该项目的目标是通过使用ALMA和新的光学/近红外设备对最远的类星体及其宿主星系进行详细观测，研究超大质量黑洞增长与最高红移星系演化之间的关系。该计划将获得在ALMA早期科学阶段红移约为6的SDSS类星体的完整样本的深度、高分辨率亚毫米连续谱和[CII]/CO线观测。这些观测将达到比当前极限更深的数量级，并将用于测量恒星形成速度、大小和宿主星系的气体运动学，并提供对星系动力学质量的估计。该计划还将在6-10米望远镜上使用新的灵敏近红外光谱仪，包括麦哲伦、LBT和VLT，以测量遥远类星体环境中的超大质量黑洞质量和化学丰度。这些观测将绘制类星体中心黑洞的吸积和生长历史，并探索它们所在星系的恒星形成和星系组装历史。这项工作的广泛影响包括本科生和研究生的培训，以及ALMA在早期科学模式下的探路使用。
