Astrophysics studies have entered a multiwavelength era. Many powerful ground- and space-based telescopes, covering the wavebands from radio to gamma-ray, have been built in the last two decades. Observations made with them have revealed a vivid picture of our universe.  High redshift quasars, especially those at z~6, are located in the very early universe. Recent observations on these rare objects have provided us unique and important information on the formation and growth of supermassive black holes and galaxies in the cosmic re-ionization era.  High-z quasars will also be objects in a quasar survey of the newly-built chinese LAMOST 4-m telescope, with which the largest quasar sample will be obtained.  

We are happy to announce that there will be a thematic program on "Multiwavelength studies on high redshift quasars" in the summer of 2009 at Kavli Institute for Astronomy and Astrophysics (KIAA) in Peking University, Beijing, China. The program will be held in Beijing in May 25 - June 5, 2009. It will be sponsored by KIAA, with financial support from Peking University and National Astronomical Observatories--Chinses Academy of Sciences (NAOC). We hope to have about 30 scientists and students working in this field to get together in KIAA and discuss the multiwavelength properties of high redshift quasars in details. The program will take a form of lecturing with 1-2 talks each day in the morning, discussing among participants and supervising students in the afternoon.

The program has no registration fee. Interested participants please send an email to Xue-Bing Wu ( to confirm their attendance and give the information of the possible arrival and departure dates before April 25, 2009. The accommodations of participants will be arranged at the ZhongGuanXinYuan Hotel in ZhongGuanYuan near the east part of PKU main campus.

How to get to ZhongGuanXinYuan Hotel of PKU from Beijing Airport:
We recommend taking a taxi to get to the hotel from the airport. It takes about 50 mins and costs about 100 RMB. Here is the location of your hotel in Chinese characters for your taxi driver.
