Keith Bannister - CSIRO – Sydney The Australian Square Kilometer Array Pathfinder (ASKAP) is one of the leading fast radio burst detection and localisation telescopes. I will review some of the scientific highlights through the lens of three distinct observing phases: the fly's-eye wide-field mode, the incoherent sum mode, and a new coherent mode we […]
Soutenance de thèse de Benjamin Arcier (Salle Coriolis, OMP) Résumé de la thèse : Les sursauts gamma sont des phénomènes transitoires extragalactiques qui continuent d'intriguer les scientifiques, 50 ans après leur découverte. Associés à des évènements violents comme la mort d'étoiles massives, ils se décomposent en deux phases : l'émission prompte, une bouffée de photons […]
Cliff Burgess - Perimeter institute We live at a time of contradictory messages about how successfully we understand gravity. General Relativity seems to work well in the Earth’s immediate neighbourhood, but arguments abound that it needs modification at very small and/or very large distances. This talk tries to put this discussion into the broader context […]
Christophe Thomazo - Univ. Bourgogne Franche-Comté Stable isotopes ratios (𝛿13C and 𝛿18O) of carbonates are central to our understanding of Earth climate and carbon cycle evolutions. These classical geochemical measurements have been developed in the mid 19th century building on the advance of gas phase IRMS laboratory instruments. With the recent development of a new […]
