We will have Raquel Galazo-Garcia giving a talk with the title "Exploring Scalar Field Dark Matter Models: Analytical Insights, Numerical Simulations, and Gravitational Lensing Prospects" The abstract is: " In the paradigm of the Standard Cosmological Model, 83% of the matter in the Universe is made up of an unknown substance called 'dark matter' (DM). […]
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.
