The MIDAS Meeting 2018


Our field is at a critical stage, in which direct observations of compact object mergers are now available to us, thanks to the pioneering efforts of the LIGO/Virgo collaboration. This represents a gigantic step forward on the observational side, that begs for a comparable push from the theoretical community. The goal of the meeting is to review the current state of our field and to discuss what is needed on the theoretical side. One thing is apparent: not all of our theoretical tools are producing the same answers to the same problems.

In a nutshell, we are in need of some form of “quality control” in theoretical simulations, and a direct convergence of our mutual efforts toward this monumental goal. A timely example relates to gravity integrators being used in N-body simulations, and the myriad of complex dynamical processes that these tools must ultimately address and compute correctly. We have therefore formed a steering group to discuss how best to proceed. So as to organize ourselves better for future collaborations.

Motivated by King Midas in Greek mythology, we call this over-arching group the MIDAS (Multi-disciplinary Initiative for the Development of Astrophysical Simulations) Collaboration for Star Cluster Simulations for aLIGO. Everything King Midas touched turned to gold, an element popularly advertised in media as a key product of NS-NS mergers.

The very first MIDAS meeting will take place next

17 – 21 December in Beijing, at the Morningside Center of Mathematics, Chinese Academy of Sciences

If you want to register, please send an email to the five organizers:

Pau Amaro Seoane – pau at
Chen Xian – chenxian at
Gong Xuefei – xfgong at
Nathan Leigh – nleigh at
Rainer Spurzem – spurzem at


1- whether you plan to attend the whole meeting or not (we’ll give preference to those attending the whole schedule)
2- name and surname, home institute

Some important notes:

1- The aim of this meeting is N-O-T to give a talk or present a poster. As a matter of fact we will have a very few number of talks, if at all, which will NOT be the aim of our meeting. We will discuss about the work which needs to be done in relativistic stellar dynamics with a focus on GW sources.

2- There will not be a registration fee.

3- There will not be posters, nor proceedings.

4- We’ll limit the number of attendees to some 50 people. We’ll be giving preference to those who stay for the whole duration.
