"Early dark energy and phantom crossing in the axio-dilaton system" Recent measurements by DESI suggest that dark energy is dynamical with an usual feature called phantom crossing.I will present models of coupled dark energy to matter where phantom crossing is natural. These models can...
"What's Your Story? Deciphering galaxy formation histories from present-day properties" Since around 100 years it has been known that our Milky Way is not the only island of stars in the Universe. Many other galaxies have since been found, featuring an immense variety of properties. Diverse...
"Lex ex Machina" Over the next few years, Rubin/LSST, Euclid, Roman, SKA, and other instruments will produce petascale, information‑rich datasets that trace stars, galaxies, and large-scale structure with unprecedented fidelity. Hidden in these data may be regularities that point to new and...
"X-ray Polarimetry of Supernova Remnants with IXPE" Supernova Remnants (SNRs) are among the most important sources of non-thermal X-rays in the sky and are likely contributors to Galactic cosmic rays, and represent ideal targets to showcase the capabilities of the Imaging X-ray Polarimetry...
"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...
