Le 1 mars 2013 À 10h30 Salle de Cours - Grande Coupole Benjamin MOSTER MPIA Garching Ab initio galaxy formation models such as hydrodynamic simulations and semi-analytic models assume a physically motivated model and try to predict statistical properties, e.g. the stellar mass...
Le 15 février 2013 À 10h30 Salle de Cours - Grande Coupole Aurélie REMY CEA Saclay As galaxies evolve, their Interstellar Medium (ISM) becomes continually enriched with metals, and this metal enrichment influences the subsequent star formation. Dwarf galaxies in the local...
Le 8 février 2013 À 10h30 Salle de Cours - Grande Coupole Michelle COLLINS MPIA Heidelberg, Allemagne Over the past few years, we have been conducting a systematic survey of the dwarf spheroidal galaxies of M31 using the Keck II DEIMOS spectrograph as part of the Pan...
Le 7 février 2013 À 10h30 Salle de Cours - Grande Coupole Michele BELLAZZINI INAF Bologne, Italie Dwarf galaxies that evolved in isolation can provide fundamental insight on the evolutionary path of dwarf galaxies, possibly keeping record of unperturbed initial conditions of...
Le 1 février 2013 À 10h30 Salle de Cours - Grande Coupole Laura WATKINS MPIA Heidelberg, Allemagne Two members of the M31 satellite population, And XII and And XIV, have extremely high line-of-sight velocities and it has been suggested that they are on their first infall into...
Le 25 janvier 2013 À 10h30 Salle de Cours - Grande Coupole Brandon CARTER LUTH, Observatoire de Paris The original (weak) version of the anthropic principle was about the probability of our situation relative to other alien possibilities. But to understand our Darwinian...
Le 18 janvier 2013 À 10h30 Salle de Cours - Grande Coupole Kostas KOKKOTAS Tübingen, Allemagne Neutron stars are the most compact massive objects in the universe with yet unknown equation of state. During their lifetime they have violent periods during which they are primary...
Le 11 janvier 2013 À 10h30 Salle de Cours - Grande Coupole Marcel PAWLOWSKI AIfA Bonn, Allemagne The Milky Way is surrounded by numerous satellite objects: dwarf galaxies, globular clusters and streams of disrupted systems. I will show that these are part of, and mostly...
Le 14 décembre 2012 À 10h30 Salle de Cours - Grande Coupole Luc DESSART LAM In this talk, I will review the basic properties of supernova light curves and spectra. I will first focus on core-collapse supernovae of Type II, which stem from the explosion of blue- and...
Le 7 décembre 2012 À 10h30 Salle de Cours - Grande Coupole Pavel KROUPA AIfA Bonn, Allemagne The pairing properties of stars and brown dwarfs are used to correct the observed object counts in a number of young populations. Because brown dwarfs are rarely companions to stars,...
