Le 9 février 2018 De 10h30 à 12h00 Yelena Stein Observatoire astronomique de Strasbourg The main topic of this talk are magnetic fields and the transport processes of cosmic ray particles. This is investigated in the three edge-on galaxies NGC 4666, NGC 4013 and NGC 4217...
Le 2 février 2018 De 10h30 à 12h00 Alessandra Mastrobuono-Battisti MPIA Globular clusters (GCs), for long considered single stellar populations, recently revealed their real complex nature. Most of them, if not all, indeed host multiple stellar populations and few very...

Le 19 janvier 2018 De 10h30 à 12h00 Pierre-Olivier Lagage CEA The last twenty years have witnessed an exceptionally fast development in the field of the extra solar planets. The known exoplanets, almost 4000 to date, show how diverse the planets in our galaxy can be. While the...
Le 12 janvier 2018 De 10h30 à 12h00 Laure Ciesla CEA Galaxies follow a bimodality in both color and morphology. They are seperated in star-forming and passive galaxies. Although observational evidences suggest that the mass and the environnement of a galaxy play a key role...
Le 22 décembre 2017 De 10h30 à 12h00 Max Gronke UC Santa Barbara The Lyman-alpha (Lya) of neutral hydrogen is the most prominent emission line in the Universe, and since its it provides a unique window into the high redshift Universe. I will discuss some examples of how...
Le 15 décembre 2017 De 10h30 à 12h00 Michaela Hirschmann IAP I give a review over the success and limitations of models for stellar and AGN feedback adopted in modern cosmological simulations, highlighting the need for feedback to predict realistic galaxy and black hole...
