Le 5 avril 2019 De 10h30 à 12h00 Christian Fendt MPIA Heidelberg I will present MHD simulations investigating the launching of astrophysical jets. The simulations treat the time-dependent evolution of the accretion-ejection structure and the subsequent collimation of the disk...
Le 22 mars 2019 De 10h30 à 12h00 Maxime Trebitsch IAP Cosmic reionization is one of the last major milestones in the evolution of the Universe. In roughly one billion years, the bulk of the hydrogen in the Universe is fully ionized by the radiation produced by early galaxies...
Le 15 mars 2019 De 10h30 à 12h00 Luc Dessart Observatoire de la Côte d'Azur Nearly all stars above 8Msun eventually form a degenerate metal-rich core and collapse. This collapse may be followed by a powerful, neutrino-driven, explosion ejecting several solar masses of...
Le 8 mars 2019 De 10h30 à 12h00 Simona Vegetti (MPA) The nature of dark matter is one of the most important unsolved problems of modern astrophysics, and strong gravitational lensing is a very promising tool to tackle this issue because the physics of dark matter strongly...

Le 22 février 2019 De 10h30 à 12h00 Fabien Louvet (Universidad de Chile) Star formation is a key astrophysical process. At a small scale, it governs the settling of planetary systems, and the complex chemistry allowing the emergence of life. At large scale, star formation...
Le 15 février 2019 De 10h30 à 12h00 William Chantereau (Liverpool) Globular clusters are among the oldest and brightest structures in the Universe, and are therefore witnesses of processes from the early up to the present-day Universe. In turn, they play a major role in...
Le 8 février 2019 De 10h30 à 12h00 Sergey Khoperskov (MPE) I will discuss the formation history of the stellar components in the Milky Way-type galaxies based on self-consistent chemodynamical galaxy formation models. Our hydrodynamical/N-body simulations initially form...
Le 1 février 2019 De 10h30 à 12h00 Paolo Bianchini (ObAS) The traditional picture of Globular Clusters (GCs) as simple stellar systems is being radically revolutionized by the synergistic efforts of theoretical advances and precision astrometry led by Gaia DR2. We now...
Le 18 janvier 2019 De 10h30 à 12h00 Lorenzo Posti (ObAS) Mass and angular momentum (AM) are the two pivotal quantities defining a whole range of structural properties of galaxies, such as their morphology. While cosmology has clear predictions on how much baryons should be...
