Le 8 avril 2016 De 10h30 à 12h00 Sebastian HOENIG University of SouthamptonMass accretion onto supermassive black holes occurs on scales beyond the diffraction limit of any single optical/infrared (IR) telescope. Thanks to the resolution power of the VLT Interferometer, we are...
Le 1 avril 2016 De 10h30 à 12h00 Tomasz Rembiasz Université de Valence Magnetorotational instability (MRI) is one of the most promising agents significantly amplifying magnetic fields in (resulting from rapidly rotating progenitors) core-collapse supernovae (CC-SNe). The...
Le 11 mars 2016 De 10h30 à 12h00 Zakaria Meliani Observatoire de Paris-Meudon Accretion disks play an important role in the evolution of their relativistic inner compact objects. The emergence of a new generation of interferometers will allow resolving these accretion disks...
Le 4 mars 2016 De 10h30 à 12h00 Jean-Baptiste COURBOT ICube - Université de StrasbourgThe Multi-Unit Spectroscopic Explorer (MUSE) instrument, located at the VLT, allows the investigation of a wide spectral range across a 1x1 arcmin sky region. In particular, its spectral...
Le 19 février 2016 De 10h30 à 12h00 Douglas SPOLYAR Stockholm UniversityDark Stars (DS) are stellar objects made (almost entirely) of ordinary atomic material but powered by the heat from Dark Matter (DM) annihilation (rather than by fusion). Weakly Interacting Massive...
Le 12 février 2016 De 10h30 à 12h00 Chatterjee Debarati Laboratoire de physique corpusculaire de Caen Neutron stars are dense compact objects, observable as pulsars by virtue of their strong magnetic fields. Further, X-ray Dim Isolated Neutron Stars (XDINSs) and Rotating...
Le 5 février 2016 De 10h30 à 12h00 Zolotukhin Ivan IRAP Toulouse We compiled a database of all photons registered by the XMM-Newton mission since its launch. To facilitate scientific usage of this valuable data collection we developed a web application on top of it which...
Le 29 janvier 2016 De 10h30 à 12h00 Mirel BIRLAN IMCCE, Observatoire de Paris M4AST (Modelling for asteroids) is a tool devoted to model and interpret spectra data in the visible and near-infrared of asteroids. It is composed by an asteroid spectral database and a set of...
Le 11 décembre 2015 De 10h30 à 12h00 Ulrich BASTIAN ARI, Heidelberg According to the official plan, the first astrometric data releases from Gaia are expected by mid 2016 (positions only) and mid 2017 (incl. parallaxes and proper motions). This is the time needed to collect...
Le 27 novembre 2015 De 10h30 à 12h00 Hervé DOLE Institut d'Astrophysique Spatiale, Orsay Le satellite Planck, pierre angulaire de l’ESA dédiée à la cosmologie et lancé en 2009, a observé la totalité du ciel pendant près de 2 ans et demi, et mesuré le fond diffus...
