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...
Le 8 décembre 2017 De 10h30 à 12h00 Martin Stref Montpellier The particle dark matter scenario is currently being probed by direct and indirect searches experiments. Making prediction for these experiments requires a knowledge of the Galactic dark matter phase space...
Le 4 décembre 2017 De 10h00 à 12h00 Hervé Beust IPAG In a now famous paper, Batygin & Brown (2016) claimed that the orbital configuration of the outermost scattered Kuiper belt objects (KBOs) discovered so far imply the presence of an additional, external ~10 Earth...
Le 24 novembre 2017 De 10h30 à 12h00 Giacomo Monari AIP Potsdam We determine the total dynamical density in the solar neighbourhood using the Tycho-Gaia Astrometric Solution (TGAS) catalogue. Astrometric measurements of proper motion and parallax of stars inform us of both the...
Le 17 novembre 2017 De 10h30 à 12h00 Jacopo Chevallard ESA The James Webb Space Telescope (JWST), scheduled for launch in October 2018, will open a largely unexplored observational window at near- to mid-infrared wavelengths (0.6-28 micron). In particular, the Near-InfraRed...
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...
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...
Le 20 octobre 2017 De 10h30 à 12h00 Hans-Walter Rix MPIA Heidelberg SDSS V will be an unprecedented all-sky, multi-epoch spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way galaxy, trace the emergence of the chemical...
