Due to the ongoing corona virus pandemic, we have decided to move the Symposium to 2022. The new dates are September 26 - 30, 2022, at the same venue and location as originally planned. We hope that by the 3rd quarter of 2022, the pandemic will be under control and world-wide and safe travel is again possible. This decision was motivated by the intend to have the Symposium in traditional form, i.e. as an in-person meeting, allowing for plenty of person-to-person scientific discussion and interaction, which would not be possible in an online format. After consultation with SOC, we decided to keep the original program largely intact, i.e. stay with the same list of review and invited speakers, which, of course, are asked to include relevant and interesting recent developments and hence will change their topics slightly where necessary. We are presently in communication with the speakers and will update the program in detail around late 2021/early 2022, before registration starts in February/March 2022. Please stay tuned.

The registration page has been closed. People, who had already registered and paid for the original conference in 2020 were reimbursed. We keep our collaboration with ContactoChile as the local organizer of the conference.

Scope of the conference

The 7th Chile-Cologne-Bonn-Symposium (in series of the former Zermatt-Cologne-Bonn-Symposia) Physics and Chemistry of Star Formation; The Dynamical ISM Across Time and Spatial Scales (now scheduled for September 26-30, 2022) continues the series of symposia on the physics and chemistry of the interstellar medium (ISM) which is held on a roughly 5 year cycle since 1988.

Following the long-term tradition of the former Zermatt Symposia on the Interstellar Medium, we will stay with the concept of a broad topical range, addressing all aspects from the large scales in time and space, i.e. the cosmological evolution of galaxies driven by star formation, down to the details of star formation in individual, local regions and to the micro-physics of molecule formation and excitation. The Symposium thus will cover the development of this research field as a whole over the last 5 years in review talks and the recent topical results in selected contributed talks.

Sessions / Reviews and Invited talks

The SOC, together with the organizers, have decided to stay with the original program of the Symposium, despite of the 2 year delay, driven by the world-wide pandemic situation. We will, for now, keep the list of review and invited speakers as originally planned, but will update the details according to recent developments in the scientific areas. The final program will be announced in late 2021/early 2022, in time before the registration is going to open in Feb/March 2022.

Each Session will allow for approximately 6 contributed talks of 15 (+5) min duration. The SOC will select about 45 contributed talks from the submitted abstracts, and will recommend which talks may get accepted as posters. The Symposium will have two Poster Sessions (2 hours each), each with 100 posters, which will also be accessible during the coffee breaks, all through Monday/Tuesday and Thursday/Friday. Thus (almost) every participant will be able to present at least one poster.

Information on Registration

Information on Abstract Submission:

Registration and Abstract Submission will open in March/April 2022.

Due to the cancellation of the Symposium in 2020 caused by the pandemic situation all registrations and abstracts received at that time have been canceled. We start with a new round in 2022.


A conference proceedings book will be published as an electronic book by the University of Cologne Library (KUPS) including a full ISBN number and DOIs. The costs for the book are included in the conference fee. Page limits are 10 pages for reviews, 6 pages for invited talks and 4 pages for contributed talks. The SOC will select a number of posters to be included like contributed talks.

The LaTeX template for the articles will be provided in time.
