Le 20 mai 2016 De 10h30 à 12h00 William Alston Cambridge Understanding accretion of matter onto black holes is one of the biggest contemporary astrophysics challenges. Accretion powers both active galactic nuclei (AGN) and black hole X-ray binaries (BHBs), which provide feedback...
Le 13 mai 2016 De 10h30 à 12h00 Florian RODLER MPIA HeidelbergOver the past 20 years, more than 2000 planets beyond our Solar system have been found. Despite the large number of planets found, we have still little knowledge about their atmospheres. In my talk, I will introduce...
Le 22 avril 2016 De 10h30 à 12h00 Salle de cours - coupole Luc BLANCHET IAPLes détecteurs d'ondes gravitationnelles ont observé le signal de la coalescence de deux trous noirs stellaires massifs à une distance d'environ 400 Mpc. Cette découverte majeure ouvre la voie à une...
Le 15 avril 2016 De 10h30 à 12h00 Salle de Cours Coupole Emmanuel NEZRI LAM - MarseilleIf we have strong evidences of the dark matter (DM) gravitationnal interactions from galactic to cosmological scales, discovering the DM nature remains one of the major issues of HEP and...
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...
