3. PCMI workshop: “Which observatories for PCMI?” (Oct. 18-21, Paris with a broadcast through zoom)
Deadline for submission of contributions: Sep. 3rd

Web site: https://pcmi-observ-21.sciencesconf.org/

Registration is free of charges but mandatory.

Rationale: The observational data gathered by state-of-the-art astrophysical facilities provide our primary source of information towards a better understanding of the impact of the interstellar medium physics and chemistry on high redshift galaxies, on star and planet formation in the Milky Way, or on the emergence of life. Opening up new regions of discovery space through increased sensitivities, angular and spectral resolutions, polarimetry, survey speeds, multi-wavelength multi-carrier studies is
essential to understand these fundamental questions of astrophysics.

This 4-day workshop aims first at mobilizing the community on the observatories under construction or evolution and on long-term research and development activities, both for ground and space observatories. It also aims at defining the scientific challenges of PCMI community within the next 5-15 years to define the space of parameters to be explored and the associated observatory characteristics.

This workshop is also about presenting current science with foreseen developments. Indeed, the science of today predicts the needs of tomorrow. The laboratory astrophysics part of the community is essential in this workshop. It is important to think ahead of time about the experiments and calculations needed to interpret future observations (eg, the X wavelength domain with Athena). Informing astronomers about what is possible/impossible from the labastro viewpoint is required (eg, the study
of ionized dust).

We are looking forward to discuss these important topics with all of you. Jerome Pety, Karine Demyk, Ludovic Biennier, Francois Levrier, Valentine
Wakelam and Patrice Theule on behalf of the SOC.

5. Postdocs in (Astro)x(Data Science) at SISSA

Application deadline:

Several positions to be filled in the group https://datascience.sissa.it/research-unit/40/astroml at SISSA, the International School for Advanced Study in Trieste, Italy.

The group brings together statistics, data science, cosmology and astrophysics, focusing on the development and application of machine learning and Bayesian methods to problems in astrophysics and cosmology, including dark matter and dark energy, supernovae type Ia, multi-messenger astrophysics and early universe physics. We are also interested in explainable AI and theoretical questions in neural networks. We are part of the newly established, cross-disciplinaryTheoretical and Scientific Data Science group (https://datascience.sissa.it/) at SISSA, funded by an 8M € grant from the Italian government. Starting in Oct 2021, we will offer a new PhD programme in Data Science, and aim at launching in the next few monthsa region-wide Data Science institute, involving several academic and industrial partners.

The postdoc positions will be 2+1 years, in fields broadly aligned with the interests of the group, with a flexible starting date, a good deal of independence, a generous travel allowance and access to state-of-the-art computational equipment. They also come with brand new offices overlooking the beautiful Trieste bay. Trieste is an historical city in the North-Eastern tip of Italy, at the intersection of many cultures, with a high quality of life, great outdoors and the highest density of PhD per capita in Europe.

I am hoping that you might bring this opportunity to the attention of potentially interested researchers (or finishing PhD students) in your network — not necessarily with a background in cosmology or astrophysics, but also (astro)particle physics, computer science or statistics; I would be particularly grateful if you encouraged women and people from under-represented groups to apply — diversity and inclusion being aspects I am keen to focus on.

Expressions of interests to me (rtrotta@sissa.it), in the form of a CV and a 2-pages research interests statement. There is no set deadline for this first, informal phase, but funding constraints mean that the positions must be filled before the end of 2022.

6. Postdoctoral fellowships in astrophysics / Paris Observatory-PSLdeadline: October 11, 2021

Applications are solicited for up to three post-doctoral fellowships in astrophysics at Paris Observatory-PSL. The positions are funded for one year, renewable for a second year.


Paris Sciences et Lettres – PSL is a new university federating nine prestigious research and higher education institutions in the fields of sciences, humanities, and arts, such as the Paris École Normale Supérieure, Paris-Dauphine University, or Paris Observatory, and involving as well ten associate institutions.

Paris Observatory is one of the largest astronomical centres in the world with 650 permanent staff out of a total of 1000 employees, and 840 publications per year. It represents one fourth of French astronomy with teams covering a wide range of research fields and participating in the largest instrumental, theoretical/numerical and experimental projects of modern astronomy. Research teams are located on three main sites, amongst which two are in the Paris area (Paris and Meudon). The third one is the Nançay astronomical radio observatory. Paris Observatory-PSL is part of a rich astronomical environment in the Paris area comprising about 600 scientists. Successful applicants will be expected to conduct research related to the priorities of the Paris Observatory laboratories and of the Virtual Observatory Paris Astronomical Data Centre (PADC), and to the themes and programmes highlighted by the Paris Observatory Scientific Council for the 2019 – 2023 period :

  • Cosmology, galaxy formation and evolution

Applications will be selected following a three-step procedure:

  1. Pre-selection of applications by the Paris Observatory research laboratories: each laboratory can select a limited number of applications depending on its size (number of research teams and number of researchers). Criteria (a), (b), and (d) are used during this first pre-selection step. A maximal number of 30 applications are pre-selected and transmitted to the Scientific Council of the Paris Observatory;
  2. Each pre-selected application is ranked according to criteria (a), (b), (c), (d) and (e) by three reviewers selected within the Scientific Council. Each criterion carries equal weight in the evaluation of an average grade. Applications are ranked according to the average grades (scores) and the 70% best applications are selected to pass this second step of the selection process;
  3. The remaining applications are discussed during the Fall session of the Paris Observatory Scientific Council, from which a list of ~10 applications are finally selected. The first ranked applications, depending on the exact number of positions offered that year, are contacted right after to be offered a position. Applications ranked up to the 10th rank (waiting list) are contacted;
  4. If a candidate to whom a position was offered declines, the position is offered to the next candidates on the waiting list until the position is fulfilled.


  • August 30, 2021: publication of the call
  • October 11, 2021 : closure of the call
  • October 13 to 27, 2021 : first pre-selection step
  • November 23, 2021 : Final selection (second and final selection steps)

The results will be communicated to the candidates after each step of the selection process.
