The team will use a new facility, the Atacama Large Millimeter/submillimeter Array (ALMA), to measure the motions of gas close to supermassive black holes at the centers of galaxies. The gas motions will be modeled to obtain precise black hole masses. Such precision is needed to test puzzling hints that black holes grow in lock step with their host galaxies. The precise masses will also anchor inventories of black holes in the local universe. The team will also study the properties of the gas. Senior team members will mentor junior members drawn from underrepresented groups; undergraduate students from California State Universities and Community Colleges will have research opportunities beyond those available in their own institutions. The team will use ALMA's exquisite angular resolution to study molecular gas disks deep in the potential well of supermassive black holes. Their goals are to (1) use initial ALMA observations to identify target systems with high-velocity rotation and (2) use follow-up ALMA observations to constrain the masses of the black holes and the properties of their cold, circumnuclear disks.

该团队将使用新的设施，即Atacama大毫米/亚毫米阵列（ALMA），以测量星系中心接近超级质量黑洞的气体动作。 气体运动将进行建模，以获得精确的黑洞质量。 需要这样的精确度来测试令人困惑的暗示，即黑洞与他们的宿主星系锁定了。 精确的群众还将在当地宇宙中锚定黑洞的清单。 该团队还将研究气体的特性。 高级团队成员将指导来自代表性不足的团体的初级成员；来自加利福尼亚州立大学和社区学院的本科生将获得超越自己机构可用的研究机会。该小组将使用ALMA精致的角度分辨率研究超级质量黑洞潜在孔深处的分子气盘。 他们的目标是（1）使用初始的Alma观测值来识别具有高速旋转的目标系统，并且（2）使用随访的Alma观测值来限制黑洞的质量以及其寒冷的透明核磁盘的特性。
