"Star formation in hierarchical molecular clouds: Questioning our certainties of universality" Understanding star formation requires addressing the challenge of determining how the discrete distribution of stars emerges from the continuous distribution of gas in molecular clouds. The...
"Stellar evolution in the JWST and PLATO era" Stellar physics is more than ever at the heart of many questions in astrophysics. In this talk I will go through a - certainly biased - review of the main challenges this discipline needs to overcome and how major missions and instruments will...
"A transformative era for studying dynamics of galaxy disks: insights from ALMA and JWST" ALMA and JWST are at the forefront of a transformative era in our understanding of galaxy formation and evolution. Their unprecedented angular resolution enables a multi-phase view of the interstellar...
" Building analytical waveforms to challenge General Relativity" In this talk, I will give an overview of why the post-Newtonian formalism is still relevant to model gravitational waves, focusing on recent synergies with other techniques and research topics. Taking the example of effective...
" Discovering the University Heritage" This talk offers an exploration of the diversity of academic heritage, encompassing buildings, gardens, and collections, assembled over centuries for teaching and research across numerous disciplines. While some of these elements are accessible to a large...
"Multi-Messenger astronomy with gravitational waves: current status and future perspectives" As an emerging field, multi-messenger astronomy has developed from its first pioneering detections into a promising and powerful approach for exploring the Universe. Even with only a small number of...
"Exploring the linear stability of flattened galactic disks using Stäckel potentials" The diversity among galaxies showcases a broad spectrum of mass and angular momentum distributions. During formation, gravitational forces drive these celestial bodies to collapse, acquiring angular momentum...
"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...
"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...
