Le 30 septembre 2016 De 10h30 à 12h00 Mirek GIERSZ Nicolaus Copernicus Astronomical Center, Varsovie I will very briefly talk about the basic assumptions behind the Monte Carlo method and discuss why this method is so fast and flexible for large star cluster simulations. I...
Le 23 septembre 2016 De 10h30 à 12h00 Jean-Baptiste FOUVRY IAP Fluctuations in a stellar system's gravitational field cause the orbits of stars to evolve. These fluctuations can either originate from external perturbers (e.g. flybys), or from the intrinsic discreteness of...
Le 9 septembre 2016 De 10h30 à 12h00 Marie MARTIG MPIA Heidelberg Thick disks are ubiquitous in nearby spiral galaxies, and many mechanisms have been proposed to explain their formation. I will first use a suite of zoom cosmological simulations to explore the connection...
Le 2 septembre 2016 De 10h30 à 12h00 Facundo GOMEZ MPA Garching During this talk I will present an overview of our recent work which aims to characterize the impact of host-satellite interactions on the observable properties of our Galaxy. Using fully cosmological...
Le 1 juillet 2016 De 10h30 à 12h00 Heddy ARAB Observatoire astronomique de Strasbourg Dust plays a fundamental role in the evolution of interstellar medium and of galaxies. Astrophysical observations combined to numerical models and laboratory studies of dust analogues...
Le 17 juin 2016 De 10h30 à 12h00 Leonard BUTSCHER MPE Garching AGNs happen in every galaxy and the feedback they generate may play a fundamental role in the evolution of galaxies. We still do not know, however, what triggers nuclear activity since active and inactive galaxies...
Le 3 juin 2016 De 10h30 à 12h00 Christophe LE PONCIN-LAFITTE Observatoire de Paris, LNE-SYRTE Les expériences de géodésie, d’astrométrie et de temps/fréquences, au sol ou dans l’espace, permettent de tester les lois fondamentales de la gravitation dans le Système...
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...
