The goal of this project is to better understand the differences between radio loud and radio quiet quasars. The project involves a three-fold approach to the problem: 1) study of the demographics of radio-loud quasars (the evolution of the radio-loud fraction with redshift and luminosity); 2) analysis of high-ionization broad emission lines for comparison with differences in spectral energy distributions, and 3) comparison of radio emission from quasars and Galactic black hole binaries.Broader impacts of the work include training of undergraduate and graduate students, and public outreach via observatory open houses and as a volunteer in a local elementary school. The grant will support a female graduate student's PhD thesis.

这个项目的目标是更好地了解射电大声和射电安静类星体之间的差异。 该项目涉及三个方面的方法来解决这个问题：1）研究射电类星体的人口统计学（射电大声部分随红移和光度的演化）; 2）分析高电离宽发射线以比较光谱能量分布的差异，以及3）类星体和银河系黑洞双星的射电辐射的比较。这项工作的更广泛影响包括培训本科生和研究生，并通过天文台开放日和在当地小学担任志愿者进行公众宣传。 该赠款将支持一名女研究生的博士论文。
