"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 […]
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 […]
"Constraining the formation and evolution of the largest main belt asteroids" Abstract Asteroids in our Solar System exhibit a wide variety of sizes, shapes, compositions, and orbital properties and provide powerful constraints for planetary system formation models. However, little is known regarding their densities and internal structure although these are fundamental properties that derive from […]
Title: Early Planet Formation: Exploration Goals for NASA's Lucy and Psyche Mission Speaker: Prof. Richard Binzel (MIT) Abstract: Two NASA spacecraft missions, Lucy and Psyche, will explore distant asteroids in our solar system that provide a window to the earliest era of planet formation. Lucy, launched in 2021 is en route to explore a group […]
