Le 29 mai 2018 De 12h45 à 13h45 François-Xavier Pineau (ObAS) Results of probabilistic cross-matches taking into account photometric parameters. After a brief introduction to the statistical basis and practical limitations of multi-catalogue positional cross-matches, we...
Le 25 mai 2018 De 10h30 à 12h00 Maria Bergemann MPIA Heidelberg The evolution of our Galaxy has been a subject of extensive studies over the past decades. A qualitative understanding of its major building blocks is now in place. Yet, the detailed history of the Milky Way...
Le 18 mai 2018 De 10h30 à 12h00 Nikolay Kacharov MPIA Heidelberg In this talk I will introduce some of the open questions in the field of globular clusters and nuclear star clusters. As one part of the colloquium, I will talk about the multiple populations phenomenon in...
Le 15 mai 2018 De 12h45 à 13h45 Kim Venn (University of Victoria) Analyses of Metal-Poor stars in the CFHT Pristine SurveyThe Pristine Survey is a narrow-band photometric survey focused on the metallicity-sensitive Ca H & K lines and conducted in the...
Le 4 mai 2018 De 11h15 à 12h30 Ortwin Gerhard MPE Garching The central few kpc of our Galaxy, the Milky Way, are dominated by the gravitational field of the Galactic bar. This talk describes dynamical models of the bar and box/peanut bulge, and what we have learnt from...
Le 4 mai 2018 De 10h30 à 11h15 Magda Arnaboldi ESO Garching I will motivate the use of Planetary Nebulae (PNs) as distance indicators, tracers of stellar populations and kinematics in cold/hot stellar galactic systems. I will then discuss the PN visibility lifetimes and...
Le 27 avril 2018 De 10h30 à 12h00 Vincent Mazet ICube Nous présenterons dans cet exposé les méthodes développées ces dernières années dans l'équipe IPSEO (ex PASEO) de Christophe Collet du laboratoire ICube. Il s'agit de susciter des discussions pouvant aboutir à une...
Le 24 avril 2018 De 12h45 à 13h45 Anu Kundu (ObAS) Understanding pulsar emission considering a rotating off-centred dipole Abstract: Past few decades have shown an exponential rise in the importance of studying compact objects possessing inherent extreme...
Le 20 avril 2018 De 10h30 à 12h00 Katharina Lutz ObAS Stars are formed from gas, with the atomic hydrogen (HI) in galaxies being the raw fuel for the formation of giant molecular gas clouds. These clouds are the birthplaces of stars. In order to continue this star...
Le 13 avril 2018 De 10h30 à 12h00 Coryn Bailer-Jones MPIA On 25 April the Gaia Consortium will make its second data release based on 22 months of mission data. The release will contain five-parameter astrometry and three-band photometry for over 1 billion stars down to...
