Le 9 novembre 2018 De 10h30 à 12h00 HongSheng Zhao University of St Andrews I will discuss some common misperceptions about dynamics and lensing. Present and future large telescopes can provide a new type of data for modelling galaxies and...
Le 26 octobre 2018 De 10h30 à 12h00 Rhys Taylor Astronomical Institute, Prague The Arecibo Galaxy Environment Survey is a large-area, blind neutral hydrogen survey, designed to observe the full range of galaxy environments without the optical biases of traditional surveys....
Le 19 octobre 2018 De 10h30 à 12h00 Payel Das Oxford Galaxy evolution seeks to understand how the featureless groups of stars in the early Universe metamorphosed into the diverse range of morphologies that can be observed today. There are a number of drivers acting on...
Le 12 octobre 2018 De 10h30 à 12h00 Pierre Maggi ObAS Supernova remnants (SNRs) are the fingerprints left in the interstellar medium by either thermonuclear (type Ia) or core-collapse (CC) supernova explosions. The Magellanic Clouds (MCs) offer an ideal laboratory for the...
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....
