"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...

"Low surface brightness galaxies in the era of deep large-sky surveys and artificial intelligence" Low surface-brightness (LSB) galaxies, which are typically fainter than the night sky, contribute to the majority of the total number density of galaxies in the universe. Therefore, they are a...
"New radiative transfer methods in numerical simulation of the epoch of reionisation" In current cosmological simulations, the radiative transfer modules generally rely on the M1 approximation, which has some glaring flaws related to its fluid-like behaviour, such as spurious pseudo-sources and...
"Probing the local low surface brightness Universe in the era of the Euclid space telescope." This thesis is dedicated to evaluating and enhancing the Euclid space telescope’s capability to detect extended and faint structures in the Local Universe—commonly referred to as Low Surface...
"Implicit Likelihood Cosmological Inference: Simulations & Diagnostics" Ongoing cosmological surveys map the large-scale structure of the Universe across immense volumes. Extracting robust cosmological information from these data requires fast, high-precision simulations of the survey...
"Dark matter and the MOND phenomenology in galaxies." We discuss the phenomenology of dark matter at galactic scales and the intriguing MOND (Modified Newtonian Dynamics) formula for the rotation curves of galaxies, the baryonic Tully-Fisher relation (BTFR) and the radial acceleration relation...
Les journées européennes du patrimoine 2025 auront lieu du 19 au 21 septembre. Le Jardin des sciences organise de nombreuses activités. Une visite de l'Observatoire astronomique est prévue le dimanche 21 septembre à 16h, mais elle est déjà complète. Vous pouvez consulter le programme...
