Rémy KOSKAS (Laboratoire Univers et Théories, Observatoire de Paris Meudon, PSL, Université Paris Cité):"Dark matter halos shape as a strong cosmological probe". Virtual Room: https://univ-amu-fr.zoom.us/j/96876832544?pwd=NnBaZEdXd3dFUFBRSkRFY05WS1d4dz09 Abstract: Halo collapse is a complex nonlinear process, intertwining both gravitational and cosmological phenomena. One of the manifestations of this complexity is the shape of the resulting present-day halos: simulations […]
The amphitheatre of the LAM hosts 2 days on the theme of optical surface specification, in the framework of the "Intercomparison" working group of the Réseau des Opticiens (ROP). A description of these days and a preliminary agenda can be found on this link: https://rop.cnrs.fr/journee-thematique-specification-des-miroirs/

"Bayesian Computational Statistics for the study of galaxy Spectral Energy Distributions" by Grégoire Aufort Abstract : The exploitation of new observation tools in astrophysics requires the development of new statistical tools in order to be effective and precise. We are particularly interested Bayesian statistics for the study of the Spectral Energy Distributions of galaxies. After […]
Dark Matter distribution and cosmological simulations – Characterization with the Minkowski Functionals PhD defense (in English) by Guillaume Bonnet. Abstract This thesis addresses the formation and evolution of structures and more specifically the dark matter distribution within halos in a cosmological context. We start by introducing the general context of structure formation in cosmology. Then […]

The cafe-club will take place at 11:00 am in the Library at LAM and on usual AMU virtual room You can find the schedule of upcoming café-clubs and the video of old ones in […]
Dear all, The Galaxy Evolution Circle will restart in a different format. Every two weeks, we will pick-up a particular subject. The idea will be to create a round table where we will discuss the following points: - An small introduction. - Classic and recent articles. - Active (LAM) people working on the subject. - Instruments. - On-going and future projects. - Perspective. For our first G.E Circle (14/Oct./15h at Mistral room) we propose to discuss Galaxies at the reionisation epoch. The idea is to maintain the discussion lively and informal. We look forward to have your presence in person.
Self-gravitating vortices in protoplanetary discs PhD defense by Steven Rendon Abstract Structures observed in protoplanetary discs could be due to large-scale vortices whose consequences on planetary formation are still uncertain. The main interest of the vortices is their ability to rapidly capture and trap the solid particles; indeed, the large clumps formed in the vortex […]
