Update (27 August 2020) 

---- An announcement has been sent on 18 Sept 2020 summarizing the latest information ----

After careful consideration, taking into account the international situation of COVID-19 around the world and ongoing  travel restrictions for part of the international community, we made the decision to hold an online meeting only. 

The conference will be held during the last week of October (26 - 30 October 2020), assuming the situation related to Covid-19 does not worsen in the next month. 

However, people who wish to come to Marseille for another reason (personal, collaboration) are accepted. We will organize the meeting room with about 300 m2 available and a normal possible attendance of 280 persons for people who are authorized to travel and wish to come to France (depending of any evolution of the policy).

  • The selected talk will be announced shortly after (September 26th, 2020).
  • Presenters will be asked to send their talk in advance. 
  • Video recording of the talks will be available,
  • Online posters will be available and a short associated presentation can be recorded.

Right now, only people from the European Union are allowed to come to France (or people already inside the EU) and from a few other countries. Hopefully, this could also evolve to more countries in the next weeks and months.

Any other information will be posted here.

Thank you.


   Before the birth of the first generation of stars (population III), the universe contained essentially only hydrogen and helium atoms. But after these first stars ignited, they synthesized in their cores nuclei of atoms heavier and heavier (the rise of metals). Some of these atoms have formed grains of dust, which is now everywhere in the interstellar medium. Dust absorbs and diffuses ultraviolet radiation and optical light, which heats the dust particles that ultimately produce radiation that is re-emitted in the infrared. This process modifies our vision of galaxies and of the universe and has dominated the universe for several billion years (the rise of dust).

    In addition to the effects of reddening and obscuration, dust grains also play a crucial role in star formation and in the physics and chemistry of the interstellar medium, such as heating and cooling processes, gas dynamics, charge transfer and the formation of H2 molecules. It is therefore important to progress in understanding the history of the formation of heavy elements in the universe as well as the different phases of the duty cycle of dust and the variation of this cycle according to the environment and the cosmic times.

    Successive generations of IR and sub-mm telescopes (ISO, AKARI, Spitzer, Herschel, ALMA, IRAM, SPT and others) have revolutionized galaxy studies in a wide range of astrophysical environments but can still hardly reach the early universe. Projects in the near future (JWST) and in study could have performances to reach this ambitious goal and to open the door to the primordial universe.

    At the same time, many theoretical advances have been made in understanding the composition, physical nature and evolution of the dust cycle and the different processes involved. It is the same for the modeling of the history of the formation of the heavy elements and their ejection in the interstellar, circumgalactic and intergalactic media during the cosmic times in the frame of the formation and the evolution of the galaxies.

    It is therefore timely to bring together theoretical and observational communities to share what we know about the rise of metals and dust in the universe over a wide range of cosmic times and to discuss effective strategies to best use our powerful current and future facilities.

Registrations are now open.

Because the meeting will be on line, all people attending the meeting will have to pay the say registration fee:

  • Everyone: 50€

In case of a strong change in the sanitary situation, for instance if a new lockdown is set in France or Europe or if more restrictions are set for the country of someone who initially planned to attend the meeting in person, refund will be possible if a justification is provided.
