莉，它是星系与其环境物质相互作用的关键环节之一。Zhijie Qu教授将介绍他在多相态星系周围介质方面的研究成果。这次的天文学学术交流活动将于2013年4月17日周一下午14:30在中国科学院国家天文台A508举行。同时，我们欢迎广大天文学爱好者和相关专业人士前来参加。ng theoretical and numerical work aimed at developing a more complete picture of the CGM. This upcoming astronomy academic exchange event will feature a fascinating discussion on the multiphase nature of the circumgalactic medium (CGM). During this event, Zhijie Qu, a professor from the University of Chicago, will be sharing his latest research findings about how the CGM plays a critical role in galaxy formation and evolution via mediating inflows and outflows. Over the years, there has been significant progress in observing and understanding the CGM's multiphase nature. Through Professor Qu's talk, we will be able to delve deeper into two of its most well-constrained phases: the hot phase and the photoionized cool phase. Focusing on these two phases, we will be able to gain a better understanding of the physical conditions that occur in the CGM, and the theoretical and numerical work that is currently taking place to develop a more complete picture of this fascinating phenomenon.eservoir that surrounds galaxies. The upcoming astronomy academic exchange event will feature a discussion about the exciting advances we can expect in our understanding of the circumgalactic medium (CGM). One of the distinguished speakers is Zhijie Qu, a KICP Associate Fellow at the prestigious University of Chicago, and a renowned expert in the field. Zhijie recently obtained his PhD from the University of Michigan and has since been engrossed in observations and modeling of the multi-phase CGM, a massive baryon reservoir that envelops galaxies. During the exchange, Zhijie will reveal some of the innovative techniques he has developed to study the CGM, providing us with a glimpse into the most current and cutting-edge research on this fascinating topic. Furthermore, he will discuss the importance of the CGM in galaxy growth and evolution, and explore how this knowledge can drive future space missions and astronomical discoveries. With Zhijie's extensive expertise and passion for the subject, this is an event that no astronomy enthusiast should miss!The celestial universe continues to inspire research and innovation, fueling our fascination and awe.
