"Constraining the properties of high-density matter with neutron star merger observations" The composition and thermodynamic properties of neutron star matter are still elusive. Being composed of high-density matter neutron stars are a natural laboratory to learn more about the fundamental...
A l’occasion d’une nouvelle publication de résultats scientifiques et de données du télescope spatial Euclid de l’agence spatiale européenne (ESA), la partie française du Consortium scientifique de la mission organise un événement presse / médias à Strasbourg. Il se tiendra le...
"The multi-messenger spectrum of the universe" Our understanding of the radiation record of the universe has advanced dramatically over the past decade. The brightness of the extragalactic sky is now measured in photons, neutrinos, and cosmic rays by observatories on the ground, in the depths...
"Mind the gap: Distinguishing disk substructures and their impact on the inner disk composition" Abstract: non communiqué...
L'observatoire astronomique sera présent aux Journées Portes Ouvertes, dans les locaux de la Faculté de Physique et ingénierie : Samedi 1er mars 2025.3-5 rue de l'Université, Strasbourg. Nous serons heureux de répondre à vos questions sur la formation en astrophysique.Plus...
"The formation, evolution, and dark matter content off barred galaxies in LCDM" The advent of high resolution hydrodynamical cosmological simulations allows us to now study the internal dynamics of barred spiral galaxies -- such as our own Milky Way -- within the full ΛCDM cosmological...
"The pattern speed of the stellar bar of the Large Magellanic Cloud measured with Gaia data" The Large Magellanic Cloud, the mini barred spiral galaxy distant by 50 kpc from the Milky Way, has been observed extensively by the ESA-Gaia satellite since 2014. For about 11 million stars, the LMC...
"A chartography of space-time: Extreme - and extremely large mass ratio inspirals and our Galactic Centre" In this talk, I will explore the scientific insights we can gain fromobserving extreme-mass-ratio inspirals (EMRIs)-phenomena involving thegravitational capture of a small compact object...
Séminaire - Matthieu Quéval "Prof après des études d’astrophysique ? Un projet professionnel tout à fait pertinent !" La carrière d'enseignant est choisie régulièrement après un master, ou après une thèse ou un postdoc. Matthieu Quéval nous fera part de sa passion,...
"Formation the Milky Way's inner stellar halo and disc: insights from numerical simulations and observations" In this talk I will present recent results regarding the formation history of the Milky Way's stellar halo and disc. Gaia has conclusively shown that the inner stellar halo is dominated...
