"Polarimetric study of the UV and X-ray emission regions in supermassive black hole neighbourhood" This thesis focuses on the reduction and analysis of polarization at high energies (ultraviolet and X-rays) in order to explore the internal geometry of Active Galactic Nuclei. Indeed, the...
"HST observations of nuclear star clusters in 41 MATLAS dwarf galaxies: properties and implications in terms of formation scenario" Debated for decades, the formation of nuclear star clusters (NSCs) --the densest stellar objects in the Universe-- currently opposes two main scenarios: the...
Rencontres Euclid-France 2025 L'Observatoire astronomique de Strasbourg a eu le plaisir d'accueillir les Rencontres Euclid-France 2025, avec une journée au Planétarium du Jardin des Sciences où les données Euclid ont été montrées en pleine voûte.L'ISU a également généreusement...
"The VESTIGE survey: reconstructing the star formation history of massive early-type galaxies through their UV and Halpha emission"Galaxies undergo remarkable morphological transformations, and it is still unclear how they change their shape from disks to spheroids, how they build up their mass...
"NGC 1851E: A millisecond pulsar in a binary system with a compact companion in the mass gap between neutron stars and black holes" Since March 2019, a large international collaboration (known as “Transients and Pulsars with MeerKAT”, or “TRAPUM”) has been using the 64-antenna MeerKAT...
"Reconstructing the history of our Universe with projected Large-Scale Structure" The last twenty years have seen a tremendous growth in the quantity, variety, and quality of multi-wavelength astronomical observations of the large-scale structure (LSS). Our ability to observe different...
27-30 Oct 2025 The CoCoNuT Meeting is a series of workshops aiming at fostering collaboration among relativistic astrophysics groups, specially within Europe. The series has been taking place yearly since 2009 and this year is hosted by Strasbourg University. This edition will be...
"The Wide-field Spectroscopic Telescope — WST" I will present the WST project, conceived as a state-of-the-art spectroscopic facility intended to provide a critital capability currently absent from the global astronomical infrastructur. WST is envisioned to play a foundational role in...
"Tracing the origin of Intermediate-Mass Black Holes in the gravitational-wave era" In the last decade, gravitational-wave observations have provided crucial insights into the populations of binary compact objects, helping to address key open questions about their mass spectrum and formation...
"Deciphering the dynamics of the Milky Way bar and spiral arms with...
