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...
Le 4 octobre 2019 De 10h30 à 12h00 Guillaume Thomas NRC Herzberg Victoria The stellar halo of our Galaxy is mostly formed by stars that were initially lying in dwarf galaxies and globular clusters, which have been disrupted by the tidal field of the Milky Way. Therefore,...
Le 27 septembre 2019 De 10h30 à 12h00 Justin Read University of Surrey Dark matter makes up most of the mass of the Universe but remains mysterious. I discuss recent progress in constraining its properties by measuring its distribution in the Universe from tiny dwarf...
Le 20 septembre 2019 De 10h30 à 12h00 Florent Renaud Lund In the Gaia era, and with more and more complete surveys, the assembly of the Milky Way is being scrutinized with an always increasing accuracy. The kinematic and chemical properties of stellar populations are...
Le 13 septembre 2019 De 10h30 à 12h00 Jean-Loup Puget IAS/ENS Les données de la mission Planck ont vérifié plusieurs prédictions génériques du paradigme d'inflation qui donne une base physique aux conditions initiales du modèle historique du "big bang". Les...
Le 6 septembre 2019 De 10h30 à 12h00 Guilet Jérôme CEA The birth of a neutron star with an extremely strong magnetic field, called a magnetar, has emerged as a promising scenario to power a variety of outstanding explosive events. This includes gamma-ray bursts, supernovae...
Le 30 août 2019 De 10h30 à 12h00 Nicolas Martin ObAS The Maunakea Spectroscopic Explorer (MSE, formerly Next Generation CFHT) is an advanced project to profoundly transform the current CFHT into a survey telescope with a 10-meter mirror and a dedicated, heavily multiplexed,...
Le 19 juillet 2019 De 10h30 à 12h00 Prof. Zhang ShuangnanInstitute of High Energy Physics, Chinese Academy of Science (Beijing) Insight-HXMT is China's first X-ray astronomy satellite and was successfully launched on June 15th, 2017. It carries three sets of collimated X-ray...
