High-Redshift Black Hole Mass Measurements with Multi-Object Reverberation Mapping

准恒星天体（qso）是遥远星系的核心，它们的极端活动是由黑洞提供动力的，黑洞的质量可能是太阳的数十亿倍。该团队将研究遥远qso的光发射如何随时间变化。如果QSO的光发射迅速变亮，那么周围的气体将在一段时间后变亮，这取决于它与黑洞的距离。这是混响映射的基础。该团队将测量气体在一些qso中变亮的时间延迟。通过对每个QSO的时间延迟进行建模，研究小组将确定其黑洞的质量和周围气体的结构。他们还将开发估算遥远qso黑洞质量的捷径。高级团队成员将培训初级成员。公众将通过公开演讲、社交媒体和天文馆展示内容了解大质量黑洞的迷人主题。该团队将完成对近800个高红移qso的多年光度和光谱监测活动。他们的目标是：(1)使用混响映射来测量qso的黑洞质量；(2)研究了qso的宽发射区结构；(3)发展高红移qso群黑洞质量估计的二次方法。

Quasi-stellar objects (QSOs) are the cores of distant galaxies whose extreme activity is powered by black holes that may be billions of times the mass of our Sun. The team will study how the optical emission from distant QSOs varies over time. If a QSO's light emission brightens quickly, the surrounding gas will brighten after a time delay that depends on its distance from the black hole. This is the basis of reverberation mapping. The team will measure the time delays for the gas to brighten in a number of QSOs. By modeling the time delay for each QSO, the team will determine the mass of its black hole and the structure of the surrounding gas. They will also develop shortcuts for estimating black hole masses for distant QSOs. Senior team members will train junior members. The public will be informed about the fascinating subject of massive black holes through public talks, social media, and planetarium show content. The team will complete a multi-year campaign of photometric and spectroscopic monitoring of nearly 800 high-redshift QSOs. Their goals are to (1) use reverberation mapping to measure the black hole masses of the QSOs; (2) study the structure of the broad emission-line regions of the QSOs; and (3) develop secondary ways of estimating black hole masses for the population of QSOs at high redshift.
