1. Prospective INP Lois fondamentales de l’Univers
L’Institut de physique du CNRS prépare sa prospective scientifique pour nourrir la réflexion sur l’évolution de la physique à l’horizon 2030 (https://www.inp.cnrs.fr/fr/prospective-scientifique).
L’élaboration de cette prospective se fait en plusieurs phases. La première phase était une enquête effectuée auprès de l’ensemble de la communauté des physiciens et physiciennes des laboratoires et des GdRs de l’INP.
À l’issue de cette consultation, 14 thématiques ont été identifiées et le travail de prospective entame sa seconde phase.
Une des thématiques porte sur les tests des lois fondamentales de l’univers (Interactions fondamentales, cosmologie, particules élémentaires, ondes gravitationnelles, physique, outils mathématiques, métrologie, constantes fondamentales…).
Nous souhaitons associer à cette prospective scientifique tout le personnel des unités du CNRS dont les domaines de recherche relèvent de cette thématique.
Pour cela, nous avons entre autres mis en place un formulaire axé sur les mesures de précision à basse énergie pour que tous ceux et celles qui souhaitent contribuer à ce travail puissent nous faire part de leur contribution.
Nous avons fixé la date limite de soumission des contributions au 22 mars 2023.

4. IAU Division J for APRIM 2023 (August 2023, Japan)
With this communication, I would like to encourage you to promote participation from the members in your Division J, for Asia Pacific Regional IAU Meeting 2023 (https://aprim2023.org) to be held in my home country Japan in August 2023.
As in other regions of IAU, the regional meeting in 2020 was cancelled, hence this year’s APRIM 2023 will provide a greater opportunity for researchers to interact with others and create or renew networks.
For your division “Galaxies and Cosmology,” the relevant session could be the following:
5. Galaxy, Galaxies and their Beginnings
The initial deadline of the abstract submission is March 10. However we may extend the closing date by a week until March 17 to ensure sufficient participation from the IAU members in this region.
Thanks in advance for your support. I am sure forwarding this email to the IAU Secretary will reach respective members, if you don’t have access to the mailing list.

7. Atelier Outils / Dark Energy (5-7 June 2023, IAP, Paris)
The WG Tools / ADE is organizing a workshop on June 5th to 7th, 2023 (included) at IAP.
https://indico.in2p3.fr/event/29631/
This “hands-on” workshop (which we hope to be the start of a series) will be the opportunity to help at getting familiar with tools commonly used in cosmology.
We have organized three blocks of tutorials:
- CLASS and its practical usage (parameters, output files, limits, …) (N. Schöenberg) ;
- MontePython to make a cosmological inference from CMB data (N. Schöenberg) ;
- Use of Monofonic/Gadget/Ramses to compute an N-body simulation, alongside the diagnostics (C. Stahl).
Additionally, we have sessions opened for contributions.
To participate to these sessions, please register (freely) on the website of the event (https://indico.in2p3.fr/event/29631/).
Travels may be funded, in particular to invite participants giving a presentation, and for young researchers (take contact with the Organizing Committee).transmis par A. Blanchard, P. Brax, S. Codis, G. Lavaux, Y. Rasera, P. Zarrouk
8. Conference second announcement: “Neutral Hydrogen as a Cosmological Probe Across Cosmic Time” (May 15th to 19th, Nazareth, Israel)
https://sites.google.com/view/arco-hi-conference23/home
Meeting Rationale:
In the last decades, probes of atomic hydrogen through the intensity mapping of the 21 cm line and Lyman-alpha emission and absorption have become essential tools for characterizing and understanding the physical conditions of the intergalactic medium (IGM) across cosmic time as well as the formation and evolution of the large scales structure (LSS) of the Universe. At early times HI 21 cm radiation provides a unique probe of the first billion years of cosmic history (z~6 – 200), and its three eras: the Dark Ages, the Cosmic Dawn, and the Epoch of Reionization. These three epochs constitute the transition of our Universe from its early linear phases to the highly complex structures that we observe around us. Each of these steps ushers the Universe into a new realm, probing different physical processes that can be used to understand the onset of structure formation in the Universe and its early stages, as well as the very nature of its initial conditions.
Towards the end of the reionization process (around z~6.5), the Lyman-alpha transition provides the main tool for studying the IGM, either through direct emission or absorption against the continuum spectra of distant sources (QSOs and galaxies). These systems have proven to be a treasure trove for studying the IGM down to redshift ~ 2.
At the low redshift range (z= 0 – 2), the 21 cm emission, observed from discreet sources and intensity mapping studies, become an important probe again. This range of redshift is currently the subject of very active research that aims, among other things, at measuring the Baryonic Acoustic Oscillations, or the general large structure of the local Universe.
Research into these topics has been driven by current state-of-the-art facilities and will benefit hugely from the new generation of ground-based Optical and IR telescopes (e.g., VLT, LSST, Subaru) and radio observatories (e.g., LOFAR, MWA, HERA, SKA, EDGES) as well as space-borne instruments, in particular JWST.
The aim of this meeting is to bring together cosmologists and IGM and LSS astrophysicists in order to focus the attention of their diverse communities on current and future challenges in this field. With the meeting, we will promote greater interconnectivity between theorists, observers, simulators, and data analysts, in order to meet the exciting challenges that we face today and will continue to face in the coming years.
Main Meeting topics:
- HI intensity mapping.
- The Universe’s Dark Ages.
- The Cosmic Dawn.
- The Epoch of Reionization.
- First Stars and Galaxies.
- The status of the high redshift 21-cm experiments.
- Lyman alpha probes at intermediate redshifts (z~6.5-2).
- Intensity mapping of Baryonic Acoustic Oscillations at z<2.
- Probing cosmic filaments with intensity mapping.
- Cosmological constraints (Dark matter and dark energy).
- Statistical measures and analysis methods.
- Synergy with JWST and other probes.
