Future Cosmology

April 23th – 29th, 2023, IESC Cargese, France

IESC Poster of the SW14

Cosmology is at the dawn of a revolution in terms of the quantity and quality of observation data on large structures. During the next two years, the Euclid mission will be launched, the Vera Rubin observatory will have its first light, followed very closely by the SPHEREx and Nancy Roman space missions. These missions will map large structures over a significant fraction of the observable universe in different ways: gravitational lensing, supernova distance, galaxy counting, cosmic voids. Given the quality and quantity of new data, scientists attempting to put future constraints on cosmology will need to be aware of all the promises and limits of the upcoming multi-wavelength datasets. The aim of this school is to provide a modern panorama on these new observatories, the different multi-wavelength probes on the physics of large scale structures, the rising tensions in cosmology, the problems caused by the influence of baryons and the opportunities provided by new multi-messengers approaches (e.g. gravitational waves). For the above reasons, the school will cover aspects of photometric and spectroscopic galaxy catalogues, weak lensing of galaxies, cosmic microwave background (including the lensing of it), a presentation on Euclid, LSST and SPHEREx and tensions/opportunities in the combination of these datasets. Participants will also be provided an overview on classical statistics computed on large scale structures to infer cosmological parameters, and new methods that are being developed.

This is the XVth school of Cosmology since 1993.

The organizers are committed to providing a safe and inclusive environment for the exchange of ideas for all participants. By participating in this meeting, you agree to follow the London Code of Conduct, as originally designed for the conference “Accurate Astrophysics. Correct Cosmology”, held in London in July 2015.

Just keep in mind that :

  • IESC (or anyone else) will not contact you whatever reasons (accommodation,…). Beware of scams !
  • A shuttle service between Ajaccio airport and the IESC will be organized by the IESC.
