Le 5 octobre 2018 De 10h30 à 12h00 Marcel Agüeros Columbia Stellar ages are notoriously difficult to measure accurately for main-sequence low-mass stars, severely limiting our ability to address questions ranging from the evolutionary state of exoplanets to the chemical...
Le 21 septembre 2018 De 10h30 à 12h00 Adriano Agnello ESO Much of today's Universe is "dark". In the concordance cosmological scenario, Dark Energy is the likely culprit for the (observed) accelerated expansion of the Universe, while Dark Matter governs the motions of...
Le 14 septembre 2018 De 10h30 à 12h00 David Elbaz CEA Our understanding of galaxy formation is largely based on the use of the Lyman discontinuity in the ultraviolet spectrum of galaxies. Discovering "Lyman break galaxies" revolutionized our vision of the distant Universe,...
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...
