The Growth of Supermassive Black Holes and Their Co-evolution with Galaxies since Cosmic Dawn

超大质量黑洞(SMBH)被认为是许多星系的中心，如果不是大多数的话。它们可以提供有关星系和黑洞(BHS)如何形成的信息，并为测试基础物理提供实验室。这里提出的工作将增强我们对SMBH如何形成的认识，并促进我们对早期宇宙的理解。这项研究将通过研究天体的光谱来测量遥远类星体中的BHS质量。这项工作将对新形成的SMBH的物理性质提供限制。这些结果将有助于研究人员解释即将到来的设施，如詹姆斯·韦伯太空望远镜(JWST)的数据。通过单历元光谱，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)显著改善类星体黑洞质量的估计。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BHS进行的调查。

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.
