Le 7 septembre 2018 De 10h30 à 12h00 Mattia Sormani Heidelberg I give an introduction to the gas dynamics in the bar region of the Milky Way, which is characterised by strong non-circular motions. I show how this allows to interpret the observed CO and HI longitude-velocity...
Le 31 août 2018 De 10h30 à 12h00 Mohammad Akhlagi CRAL Astronomical instrumentation has greatly advanced over the last 40 years: with digital detectors, space telescopes and +8m class ground-based telescopes for example. However, the signal-based detection paradigm (for...
Le 29 juin 2018 De 10h30 à 12h00 Tom Richtler Universidad de Concepción The question whether elliptical galaxies fall onto the same baryonic Tully-Fisher-relation as spiral galaxies, obviously is critical for the universal character of the phenomenology among galaxies....
Le 22 juin 2018 De 10h30 à 12h00 Marc Huertas-Company Observatoire de Paris Thanks to rapidly improving technology, astronomy is entering the big data era. New surveys that will be available in 2-5 years will contain multi-wavelength images of billions of galaxies and...
Le 19 juin 2018 De 12h45 à 13h45 Karina Voggel (Utah Uni.)"The hunt for super-massive black holes in UCDs - Stripped nuclei as tracers of the assembly history of a Galaxy Cluster”Abstract: Central super-massive BHs (SMBHS) have been discovered in five high mass ultra-compact...
Le 15 juin 2018 De 10h30 à 12h00 Paul-Antoine Hervieux & Giovanni Manfredi Université de Strasbourg Depuis son lancement en 2010, notre équipe fait partie du projet international GBAR (Gravitational Behavior of Antihydrogen at Rest, http://gbar.web.cern.ch/) qui vise à mesurer...
Le 12 juin 2018 De 12h45 à 13h45 Frederic Marin (ObAS)An exceptional disclosure of the hidden AGN in NGC 1068 thanks to 50 years of broadband polarimetric observationIn this contribution, I present the first broadband polarization spectrum of an active galactic nuclei (AGN) by...
Le 5 juin 2018 De 12h45 à 13h45 Paolo Bianchini (McMaster University/ObAS)A three-dimensional view of the internal rotation of globular clustersGlobular clusters (GCs) are old stellar systems for long considered spherical and non-rotating. However, in recent years, an...
Le 1 juin 2018 De 10h30 à 12h00 Wim de Boer Karlsruhe Institute of Technology The so-called Fermi-excess in the diffuse Galactic gamma-ray sky is observed as a shift of the maximum in the E^2 weighted gamma-ray spectrum from 0.7 GeV to around 2 GeV. Such a shift can be...
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...
