Webinaire ASNUM Natalia Porqueres CEA Pixel-level analysis of weak lensing maps Voir le Replay : https://astrotube.obspm.fr/w/4d6QSZk99gFbepz1ESkbiX Extracting the full information content of the weak lensing data requires analysis methods that are both highly precise and maximally informative. The standard analysis, based on correlation functions, discards information in the data and relies on simplifying assumptions in…

Webinaire ASNUM Clément Baruteau IRAP Hydrodynamical simulations of the reflex instability in protoplanetary discs Replay : https://astrotube.obspm.fr/w/r34pJg4Y6LwExtiZwREV8z Theoretical studies of protoplanetary discs have a long history, with many works on what instabilities may grow, and how they impact disc evolution and planet formation. By running long-term hydrodynamical simulations of disc-planet interactions, we have recently (and…
