or our next G.E. Circle - 29 March EXCEPTIONALLY AT 14h @ Mistral - we propose to talk about Galaxy Simulations. The idea is to continue with the format of a round table, with a lively and informal discussion for basic to advanced subjects. This time we will have the presence of Emmanuel Nezri, Jean-Charles […]
The (spring) magnetosphere of Uranus probed by a decade of HST observations of its ultraviolet aurorae The re-detection and long-term monitoring of the ultraviolet aurorae of Uranus with the Hubble Space Telescope during the past decade has provided a new, so far unique, mean to remotely investigate from Earth the asymmetric magnetosphere of Uranus since its discovery by Voyager […]
Title: Progress and surprises in studies of early galaxies with JWST Richard Ellis, University College London Abstract: I will attempt to briefly review the astonishing progress made in studies of early galaxies during the first two years of JWST science operations. Although redshift frontiers have been extended beyond those reached with HST and large ground-based […]
The annual meeting of astronomers is taking place in Marseille, organised by LAM, with the SF2A. All the informations are available there: https://journees.sf2a.eu/
Friday the 28th of June at 3pm we will have the pleasure to hear at Martin Karcher (LAM) presenting his paper: "Towards an optimal marked correlation function analysis for the detection of modified gravity" Which abstract is: "Modified gravity (MG) theories have emerged as a promising alternative to explain the late-time acceleration of the Universe. […]

The next galaxy evolution circle will discuss the contribution of SKA to galaxy evolution. We will take advantage of the presence of Marta Spinelli (talks on Thursday 14h and Friday 9:30) for this 2h discussion which will cover: Cosmic dawn and reionisation Cross-correlation with Euclid (simulating Gaia of the 21cm line in cones) General 21cm […]
This Friday the 12th of July at 15:00 we will have the pleasure to hear at Leo Buron (M1 Magistère Physique Fondamentale Université Paris-Saclay) presenting the work carried on so far on his internship supervised by Nicolas Martinet. Title : "Optimizing cosmological parameters sampling for deep learning applications of cosmic shear" Abstract: "Weak lensing cosmic […]
