Subject: Mini-symposium « Build-Up of Galaxy Clusters »

Dear colleagues,

you are welcome to attend the mini-symposium „Build-Up of Galaxy Clusters“ to be held during the Galaxy and Cosmology Division Day on 24 and 27 August 2018 at the XXX IAU General Assembly in Vienna.


As the first structures to collapse, galaxy clusters have to be seen as the earliest fingerprint of galaxy formation and evolution. A crucial epoch for galaxy evolution and formation are the first billion years of the universe (beyond redshift z=1) coming along with an enhanced star formation and black hole activity compared to the local universe and a huge growth of stellar mass both in cluster and field galaxies.

We will focus on the formation of these high-density environments and the evolution of their star-formation activity in the distant universe. The contributions will be based both on observational and theoretical studies spanning the whole range of the electromagnetic spectrum. Following key topics will define the framework of our symposium:

  • formation of (proto)clusters in the early universe and their evolution over cosmic time;
  • (proto)cluster search techniques;
  • evolution of the star-formation activity and star-formation rate density (relation) in clusters at different epochs;
  • molecular gas properties and star-formation efficiency of galaxy cluster members.

Registration is already open with abstract submission deadline 28 February 2018. Detailed information - registration, abstract submission, deadlines, travel grants - on our meeting you will find at the symposium´s webpage ( Please feel free to contact the chair Helmut Dannerbauer (Instituto de Astrofísica de Canarias) if you have any questions or queries at

We apologize if you receive this message more than once but would like to ask you to distribute this announcement among your colleagues as widely as reasonable.Thank you very much and many greetings,
