Exploring the sources of cosmic reionization

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...

On the diversity of Type II supernova light curve and spectra

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...

Strong gravitational lensing as a clean observational probe of dark matter

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...

The exciting life of old stellar clusters

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...

A renewed look at Globular Clusters in the era of precision astrometry

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...

Probing galaxy formation with rotation curves

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...

Séminaire au Collège de France

Le 14 janvier 2019 De 17h45 à 18h45 Dominique Aubert, professeur à l'Observatoire astronomique de Strasbourg, a donné le 14 janvier 2019 un séminaire au Collège de France sur la simulation de la formation des premières structures. Retrouvez sa présentation ainsi que le...
