Le 20 décembre 2019 De 10h30 à 12h00 Allison Man University of Toronto A fundamental question in galaxy evolution is how galaxies acquire diverse colours and morphologies. The current paradigm suggests that massive galaxies experienced accelerated growth in the early Universe...
Le 13 décembre 2019 De 10h30 à 12h00 Nicolas Gillet ObAS The upcoming flood of data from radio 21cm and the launch of JWST (expected soon) will dramatically change our understanding of the early Universe and our understanding of the formation of galaxies. I will present the...
Le 6 décembre 2019 De 10h30 à 12h00 Ute Lisenfeld Universidad de Granada Galaxy interaction can affect strongly the star formation activity and the molecular gas content of galaxies. Frequently, interaction enhances both quantities, but this is not always the case. I will...
Le 29 novembre 2019 De 10h30 à 12h00 Fabio Acero CEA The large amount of energy released in the supernova explosion leads to the creation of a fast shock wave which is an important source of cosmic-rays, kinetic and thermal energy in the interstellar medium. Supernovae are...
Le 22 novembre 2019 De 10h30 à 12h00 Stefan Jordan ARI Heidelberg Since 2014, ESA's Gaia satellite measures the positions of a huge number of stars of our Milky Way in order to gain a better understanding of the structure and evolution of our home galaxy. In recent...
Le 15 novembre 2019 De 10h30 à 12h00 Marc-Antoine Miville-Deschênes CEA Today we fundamentally do not understand the process of formation of collapsed structures in the Universe. How the injection of energy, mass, and metals from stars and galaxies play against the forces...
Le 8 novembre 2019 De 10h30 à 12h00 Melaine Saillenfest IMCCE Trans-Neptunian objects have complex orbital dynamics involving mechanisms as diverse as close encounters with Neptune, chaotic scattering driven by resonance overlap, secular effects from the giant planets,...
Le 25 octobre 2019 De 10h30 à 12h00 Sarrvesh Sridhar Astron Non-thermal radio continuum emission is an excellent tracer of magnetic fields in galaxies. Historically, observations of galaxies at low radio frequencies (below 1 GHz) have suffered from poor angular resolution...
Le 18 octobre 2019 De 10h30 à 12h00 Jackson Said University of Malta The standard model of cosmology has shown remarkable success in explaining cosmological observations in recent decades. This model consists of Einstein's theory of general relativity, the standard model of...
Le 11 octobre 2019 De 10h30 à 12h00 Jonathan Freundlich Hebrew University Galaxy history is marked by a peak of star formation ten billion years ago and a subsequent drop of the star formation rate (SFR) by an order of magnitude. To understand this evolution, it is crucial...
