C.E.G.O. initiative China Einstein Gravitational wave Observatory: 

C.E.G.O. initiative China Einstein Gravitational wave Observatory R. DeSalvo In behalf of: Tang Keyun, Wang Yunyong, Zong-Hong Zhu

Why am I talking to you: 

Why am I talking to you Zong-Hong Zhu and Tang Keyun were scheduled to be here in Aspen to present CEGO, to present Zong’s past esperience in GW analysis as a postdoc in TAMA To present their proposed data analysis activities in Beijing Normal University To initiate the process (with Peter S.) for application of membership to the LSC

Why am I talking to you: 

Why am I talking to you They both had trouble fingerprinting and having a visa in time. Albrecht and myself assisted them in fostering their proposal for CEGO in China They sent me an e-mail to ask me to make a presentation for them. Brief history of CEGO The present status of the initiative.

China has a long history of interest in the Universe:

How did it happen: 

How did it happen In 2003 Wang Yunyong, visitor at Livingston got interested in GW detection Getting time to leave, looking for a way to continue, contacts Tang Keyun of Geophysics Institute of Beijing Tang Keyun proposes to Academia Sinica the idea of a Chinese group at LSC Instead of forming a group to join LSC, they are invited to propose a Chinese interferometer ! !

Initiative status Conditional support from CAS (Cinese Academy of Science) NSFC National Science Foundation of China) MOST (Ministry Of Science and Technology) Already received full Scientific approval from Academia Sinica, LIGO, Virgo-EGO, TAMA, and GWIC Applying for initial funding

Tentative program: 

Tentative program First stage: Training, organizing and designing test interferometer Seek second approval Second stage: construction of mid-size test interferometer, design of full size facility Seek final approval Third stage: facility construction

Problems and solutionsmost Chinese senior scientist have no knowledge of GW and doubts to dispeldivulge information about GW in Journals, Magazines, Newspapers publicize positive opinion from other chinese and foreign senior scientists(seminars and workshops) :
