The Sphinx simulations: the first billion years and cosmic reionisation

Le 10 novembre 2017 De 10h30 à 12h00 Joakim Rosdahl CRALThe epoch of reionisation marks a major shift from a cold neutral Universe to a warm ionised one, a transition which was thought to be powered by UV radiation emitted from young massive stars in the first galaxies.Our...

Structures in the Galactic Anticenter and their relation to Sagittarius

Le 3 novembre 2017 De 10h30 à 12h00 Chervin Laporte MPA/Victoria I will present self-consistent N-body models of the interaction between Sgr and the Milky Way and show how these relate to various observations of the Galactic Anticenter. In particular, I will show that the...
