Proposal ID: AST-0237391Institution: University of KentuckyPI: Levenson, NancyDr. Nancy Levenson is awarded a CAREER grant at the University of Kentucky for an integrated program of research and education to study the obscuration by dust and resulting reprocessing of energy in active galaxies, ultimately revealing the intrinsic accretion power of their central engines. She and her students will observe nearby samples of obscured active galactic nuclei (AGN) with three specific objectives: (1) to measure the local physical conditions and distribution of material in the obscuring regions; (2) to identify reliable signatures of AGN, even when they are strongly obscured; and (3) to reveal the connection between circumnuclear starbursts and AGN. This work will use spectroscopy and imaging at X-ray and infrared energies, specifically considering the effects of strong obscuration and intense star formation, which can alter the net emission significantly. The related educational program will enhance the undergraduate astronomy concentration at the University of Kentucky, improve the education of non-scientists, and develop students' abilities through research. Dr. Levenson will increase the effectiveness of the astronomy concentration by creating an intermediate-level astrophysics course, increasing student involvement in research, and producing new publicity about the program. In teaching both science and non-science majors, she will apply effective pedagogies that emphasize active learning, such as collaborative learning, peer instruction, and assigned writing. Finally, Dr. Levenson will mentor undergraduate and graduate students, directing their work in the research program.

提案ID：AST-0237391机构：肯塔基大学PI：Levenson，NancyDr.南希·莱文森获得了肯塔基大学的职业资助金，以表彰其研究和教育相结合的项目，研究活动星系中尘埃的遮蔽和由此产生的能量再处理，最终揭示其中央引擎的内在吸积能力。她和她的学生将观察附近被遮挡的活动星系核(AGN)样本，目的有三个：(1)测量遮挡区域的局部物理条件和物质分布；(2)识别AGN的可靠信号，即使它们被强烈遮挡；以及(3)揭示核周恒星爆发与AGN之间的联系。这项工作将使用X射线和红外能量下的光谱和成像，特别是考虑到强遮挡和强烈恒星形成的影响，这可能会显著改变净辐射。相关教育项目将提高肯塔基大学本科生的天文学专注度，改善非科学家的教育，并通过研究培养学生的能力。莱文森博士将通过开设一门中等水平的天体物理课程、增加学生对研究的参与度以及对该项目进行新的宣传来提高天文学专业的有效性。在理科和非理科专业的教学中，她将采用有效的教学方法，强调主动学习，如合作学习、同伴指导和指定写作。最后，莱文森博士将指导本科生和研究生，指导他们在研究项目中的工作。
