Probing the continuum dust properties of high-z dusty galaxies using NOEMA AbstractThe study of dusty star-forming galaxies (DSFGs) is an ongoing frontier in astrophysics, continuously yielding new insights into these cosmic nurseries from the early Universe. Thanks to advancements in...
Testing the concordance model with large-scale structures AbstractWith the advancement of data quality and escalating tensions, the cosmological model faces mounting challenges. If these tensions persist and are not attributed to observational systematics, they could precipitate a paradigm...
Modeling of stellar streams from globular clusters in the Milky...
The many facets of the Aladin project Abstract Aladin is one of the key services in CDS, aimed at visualizing images of the sky together with additional information. Indeed, since the beginning, more than 30 years ago, the scope of the project has been to put astronomical images in context...
Probing dark energy with higher order weak lensing statistics Abstract Understanding the accelerated expansion of the Universe is one of the most important challenges of modern cosmology. Thanks to the development of large dedicated surveys (Euclid, Rubin, Roman), weak-lensing cosmic shear...
Numerical CLONES of the local Universe: kesako and why? Abstract As a field without ground truth, cosmology relies on cosmological simulations for data interpretation. This talk will present a peculiar type of cosmological simulations constrained to reproduce our local Universe within about...
Galactic stories told by their stars Abstract Being both a former and new member of the Observatory family, I will start this seminar with a brief introduction about myself, my career path, and how my hobbies put me too often in near-death situations. I will then switch to the connection...
The Zoo of Compact Objects and X-ray Binaries in the Center of the Milky Way Abstract The Galactic Center (GC) harbors the highest concentration and a rich variety of compact objects such as black holes, neutron stars, and white dwarfs in our galaxy. The compact objects and their binary...
Dark Matter Across Galactic Scales and Cosmic-time: current challenges and perspectives Abstract Observations from new generation spectrographs, on Very Large Telescopes, has allowed us to study the resolved velocity profiles, or rotation curves, of galaxies at high redshifts (z=0.6-3.0)....
