Le 28 juin 2013 À 10h30 Amphithéâtre - Grande Coupole Erik HOEG Niels Bohr Institute Copenhagen, Danemark From an experiment in Copenhagen in 1925 to the Hipparcos and Gaia space missions. Astrophysicists need accurate positions, distances and motions of stars in order to...
Le 21 juin 2013 À 10h30 Amphithéâtre - Grande Coupole Eddie SCHLAFLY MPIA Heidelberg, Allemagne We present work studying the three-dimensional distribution of dust inthe Galaxy, derived from Pan-STARRS1 stellar photometry, covering almost the entire sky north of declination...
Le 14 juin 2013 À 10h30 Salle de Cours - Grande Coupole Francesco TAMBORA Observatoire Astronomique de StrasbourgThe X-ray spectrum observed in X-ray Binaries (XRBs) and Active Galactic Nuclei (AGN) is complex and constituted by several components, due to the circumnuclear...
Le 7 juin 2013 À 10h30 Salle de Cours - Grande Coupole Sambaran BANERJEE AIfA Bonn, Allemagne In this talk, I discuss two of our recent studies. In the first part, I talk about our studies to explain the observed kinematic and structural properties of two well-studied very...
Le 31 mai 2013 À 10h30 Salle de Cours - Grande Coupole Mordehai MILGROM Weizmann Institute, Israel After an introduction of the MOND paradigm through its basic tenets, I will concentrate on one facet of MOND: the phenomenological laws that follow essentially from only the basic...
Le 24 mai 2013 À 10h30 Salle de Cours - Grande Coupole Stacy McGAUGH Case Western Reserve University, USA Recent observations have revealed many new low surface brightness galaxies in the local universe. These objects provide unique insights into the evolution of galaxies....
Le 17 mai 2013 À 10h30 Salle de Cours - Grande Coupole Denis BURGARELLA OAMP Marseille Using new homogeneous Luminosity Functions (LFs) in the FUV (VVDS) and in the FIR Herschel/PEP and Herschel/HerMES), we study the evolution of the dust attenuation with redshift. With this...
Le 3 mai 2013 À 10h30 Salle de Cours - Grande Coupole Brad GIBSON UCLAN, UK The history of disk galaxy simulation is dotted with remarkable successes, tempered by frustrating impasses, including an inability to recover anything remotely similar to the Milky Way. Recent...
Le 26 avril 2013 À 10h30 Salle de Cours - Grande Coupole Bertrand GOLDMAN MPIA Heidelberg, Allemagne From Haleakala in Hawaii, the PanSTARRS1 project routinely observes all the sky North of -30 declination in five optical bands, several times a year. This unique survey combines...
Le 19 avril 2013 À 10h30 Salle de Cours - Grande Coupole Sandrine COURTIN IPHC Strasbourg Nuclear fusion is the dominant process occuring in ion-ion collisions at moderate and low bombarding energies. It has been widely explored for medium-heavy to light nuclear systems. Fusion...
