Registration is now open: please read the "Information on Registration" and proceed to the registration web page from there.

We now decided that the symposium will be held as an in person conference (unless drastic COVID19-related developments force us to fall back to an online only meeting).
We extend the deadline for registration with abstract submission for talks until 22nd May 2022 (registration with poster contribution or without any talk/poster are possible until early September)

26th September - 30th September Conference  


Due to the worldwide pandemic situation, we had shifted the Symposium, originally planned in 2020, twice. After thorough discussion with the SOC and LOC, we now decided to have the Symposium as an in-person meeting at the dates announced already last year, September 26 - 30, 2022, and at the originally planned venue and location, Puerto Varas, Chile. We all miss the important opportunity of personal contact and spontaneous and in-situ planned discussions, both in the coffee breaks, during dinner, in the evening in pubs and bars, or during hiking trips. This type of interaction has immeasurable scientific value that on-line only meetings cannot provide. Travel and CO2 footprint are an issue as well, therefore we will provide opportunities for CO2-compensation. However, given the experience over the last two years, we are aware that it is wise to keep the option of an on-line fall-back.

in-person versus on-line fall-back
We will be able to make the decision to switch to an on-line meeting anytime until 4 weeks before the conference, pending on the developments of the COVID situation and travel regulations. The local hotels (the ones referred to on the "accommodation" web page), have agreed to a full, no-cost cancellation policy on the hotel rooms. Should it be necessary to switch to an online format, we will re-imburse the registered Symposium participants for the reduced on-line Symposium fee. The participants, of course, have to carry the risk of their flight bookings: early booking of cheaper tickets, risking that they become obsolete if we switch to the on-line scenario, or later booking, but of potentially more expensive tickets.
For the on-line scenario we still offer the possibility for a reduced number of participants to come to Puerto Varas (in particular Chilean residents and participants from the host institutions of the conference) which are able to travel despite of potential COVID restrictions.

The registration page is open since April 1st 2022 with a detailed description of the conference fees and accommodation options. The conditions for partial re-imbursement of the conference fee and cost-neutral cancellation of the hotel reservations are specified under "Cancellation and refund policies", in case the pandemic situation forces us to switch over to an on-line format over the next few months.

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. We were pleased to see that almost all of the speakers stayed on board and are looking forward to an in-person meeting again.

The SOC recommended to include  an additional session VI: "First results with the JWST". The deadline for submission of contributions (talks/posters) for this session will be 31th July.

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.
