The Silk Road Project Team is dedicated to computational studies of the evolution of planetary systems, star clusters, galaxies and galactic nuclei, black holes and gravitational wave emission. Our two main project nodes are Beijing, China (NAOC and KIAA) and Heidelberg, Germany (ZAH-ARI); we collaborate closely with institutions and colleagues from Kiev (Ukraine) and Almaty (Kazakhstan) and several other countries (e.g. Chile, Italy, UK, Pakistan, Austria,...). We are dedicated to teach and promote the use of new supercomputing facilities in China and abroad.


Our project is a bridge between China and Germany, with links to Asia, Europe, Americas ... 
  ...through this bridge we exchange students, knowledge, scientists... 
       ...work together for new technologies, and also for mutual cultural respect and understanding...


Our Main Research Projects are:

  • Binary Supermassive Black Holes and Gravitational Waves in Quiet and Active Galactic Nuclei 
 Burrau's Three Body Problem (solved with S. Mikkola's Chain Program)  Binary Active Galactic Nucleus (Komossa et al.)   Binary Black Hole and Gravitational Wave European Gravitational Wave Observatory Globular Cluster M15 by Hubble Space Telescope
  • Dynamical Evolution of Stars and Gas in Galactic Nuclei and Dense Star Clusters  
  • How are planetary systems forming and evolving (in star clusters)?  
  • How can we design supercomputers which are faster and consume less energy?

8th KCK Workshop


The 8th Kazakhstan-China-Korea (KCK) workshop on stellar dynamics and related fields  (star clusters, stellar evolution, gravitational waves, black holes in galaxies) took place Dec 19-21, 2016, in Kunming, Yunnan (hosted by YNAO, and co-organized by Jinming Bai (YNAO), Hyung Mok Lee (SNU), Rainer Spurzem (NAOC/KIAA), and Chingis Omarov (NCSRT). For links to the program and conference picture see  8th KCK Workshop . The Korea-China-Kazakhstan workshop takes place every year since 2009, it started as a Korea-China workshop to foster regular exchange between the teams of Hyung Mok Lee (SNU) and Rainer Spurzem (NAOC).


China South Africa Bilateral Workshop

The First South Africa-China Bilateral Astronomy Conference “Cosmology with Large Surveys” was held in Durban, South Africa, Dec. 19-26, 2016; see NAOC link here . It was hosted by Prof. Ma Yinzhe of UKZN (University of KwaZulu-Natal), see their conference home page here. The detailed program and many talk slides can be direcly downloaded , including the talk of Rainer Spurzem presenting the Silk Road Project and "Black Holes and gravitational waves from dense star clusters" (3.2 MB).


New Chinese Supercomputer Nr. 1

The current list of 500 fastest supercomputers in the world shows for the first time two Chinese supercomputers on the two top spots - number 2 is the already well known Tianhe-2 Supercomputer using Intel processors and accelerator. But the new number 1 system is the Taihu Supercomputer, which solely uses Chinese processor technology, reaches 125 Pflop/s with more than ten million cores, and puts a considerable distance in performance to the still fastest US supercomputer. See this link for the news on Taihu, and this link on the top 500 list.


7th KCK Workshop

The 7th Korea-China-Kazakhstan Workshop (organized by Hyung Mok Lee, Rainer Spurzem, Chingis Omarov) took place at NAOC Dec. 14-16. For conference picture (low res) (high res), links to talks, program see http://silkroad.bao.ac.cn/web/index.php/conferences/7th-korean-chinese-meeting (Pictures Riko Schadow)


Whisky Bottle for Million Bodies awarded to Long Wang

 SIlk Road Project Team Member Long Wang (last year Ph.D. student at KIAA/PKU) has been awarded a bottle of whisky by Douglas Heggie during the MODEST-15S Conference in Kobe, Dec. 7-11. In 2010 Douglas Heggie announced the award of a 50 EUR bottle of whisky at the
 Lorentz Center Workshop, see p. 7 of
  http://www.lorentzcenter.nl/lc/web/2010/400/presentations/Heggie.pdf to encourage more and better simulations of globular clusters.
