We are pleased to announce that a workshop entitled "East-Asia AGN Workshop 2015" will be held in Changchun, China, on July 14-16 2015. This is the third of a series of workshops for getting together scientists working in the East-Asia region in the AGN field. The previous two workshops, held respectively in Jeju, Korea in September 2012 and in Sapporo, Japan in August 2013, were very successful. These workshops provided a lively, stimulating forum for presenting and discussing new results, as well as exchanging ideas, which cover a wide range of topics in AGN research, including both theoretical modeling and observational investigation in multiple wavebands. The ultimate aim of this series of workshops is to foster existing collaborations, and to initiate new ones, among AGN researchers in East Asia countries. Thanks to the short distances within only several hours flight among these countries, there is great and promising potential of fruitful collaborations. Starting and fostering collaborative activities at the current stage is especially important as we are entering an exciting era of the advent of large international facilities, including ALMA, Astro-H, TMT and GMT. Motivated by feedbacks from the participants of the previous workshops, this workshop will put special emphasis on encouraging and initiating new collaborations. The conference will be held in Changchun, the capital city of Jilin province in northeast China, which is closer to both Korea and Japan than many of the Chinese cities. Changchun is known for its cooler climate in summer and the conference venue is a popular touristic site. We would strongly encourage you to keep your schedule available during this period! We will limit the number of participants to ~ 60 to ensure close interaction among participants. Further details will be announced in the 2nd announcement that will be distributed in May.
