Supermassive black holes (SMBH) are thought to be at the center of many, if not most, galaxies. They can provide information about how galaxies and black holes (BHs) form, and provide a laboratory for testing fundamental physics. The work proposed here will enhance our knowledge of how SMBHs form and advance our understanding of the early Universe. The research will measure the masses of BHs in distant quasars by studying the spectra of the objects. The work will provide constraints on the physical properties of newly-formed SMBHs. The results will aid researchers in interpreting data from upcoming facilities such as the James Webb Space Telescope (JWST).Through single-epoch spectroscopy, the investigators will use the technique of reverberation mapping to estimate BH mass in distant quasars. They will significantly improve quasar BH mass estimation over a wider range of distances (hence, ages). The statistics derived will help guide future investigations on early-stage BHs using JWST, 30-meter telescopes, and upcoming time-domain multi-object spectrograph projects.

超大质量黑洞（SMBH）被认为是许多（如果不是大多数）星系的中心。 它们可以提供有关星系和黑洞（BH）如何形成的信息，并为测试基础物理学提供实验室。这里提出的工作将增强我们对SMBH如何形成的知识，并促进我们对早期宇宙的理解。 该研究将通过研究物体的光谱来测量遥远类星体中黑洞的质量。 这项工作将提供新形成的SMBH的物理性质的限制。 这些结果将有助于研究人员解释来自詹姆斯韦伯太空望远镜（JWST）等即将到来的设施的数据。通过单历元光谱学，研究人员将使用混响映射技术来估计遥远类星体中的BH质量。 它们将在更大的距离范围内（因此，年龄）显着改善类星体BH质量估计。 得出的统计数据将有助于指导未来使用JWST，30米望远镜和即将到来的时域多目标光谱仪项目对早期BH的调查。
