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...
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...
Le 14 décembre 2018 De 10h30 à 12h00 Michal Bilek (ObAS) The purpose of this talk will be to introduce myself and my work so far. Modified Newtonian Dynamics (aka MOND) is the leading alternative to the dark matter hypothesis in galaxies, suggesting a modification of the...
Le 7 décembre 2018 De 10h30 à 12h00 Aurel Schneider (ETH Zurich) I will discuss the most promising gravitational probes to constrain non-cold or collisional dark matter scenarios. This includes dwarf galaxy statistics, weak lensing, and the global 21-cm signal....
Le 30 novembre 2018 De 10h30 à 12h00 Wilma Trick MPA Garching The second Gaia data release from April 2018 has revealed an astounding amount of non-axisymmetric stellar substructure in the Milky Way. In this talk, I will present the orbit structure of the Galactic disk...
Le 23 novembre 2018 De 10h30 à 12h00 Max Gronke UC Santa Barbara Galactic winds are large-scale, multiphase outflows from galaxies and crucial for the galactic ecosystem. They are, thus, a potent probe for the underlying feedback mechanisms. However, these winds are still...
Le 16 novembre 2018 De 10h30 à 12h00 Jonathan Braine LAB, Bordeaux Systematic rotation of molecular clouds was detected for the first time in the Local Group spiral Messier 33, where a sample of 566 molecular clouds is available. There is a clear preference for prograde...
Le 9 novembre 2018 De 10h30 à 12h00 HongSheng Zhao University of St Andrews I will discuss some common misperceptions about dynamics and lensing. Present and future large telescopes can provide a new type of data for modelling galaxies and...
Le 26 octobre 2018 De 10h30 à 12h00 Rhys Taylor Astronomical Institute, Prague The Arecibo Galaxy Environment Survey is a large-area, blind neutral hydrogen survey, designed to observe the full range of galaxy environments without the optical biases of traditional surveys....
