Abstract: In this talk I will present recent work on the rigorous justification of the geometric optics approximation for the Einstein vacuum equations, and its link with the Burnett conjecture in general relativity. I will start by presenting the...

Abstract: Intestinal organoids capture essential features of the intestinal epithelium such as crypt folding, spatial compartmentalization of different cell types, and cellular movements from crypt to villus. Each of these processes and their...

The cycle of gas in and around galaxies plays a fundamental role in galaxy formation. Recent hydrodynamical simulations have managed to reach (sub-)parsec-scale resolutions to follow the small-scale physics in the interstellar medium (ISM). As our...

Extracting information from stochastic fields is a ubiquitous task in science. However, from cosmology to biology, it tends to be done either through a power spectrum analysis, which is often too limited, or the use of convolutional neural networks...

Large galaxy surveys like the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) are changing how we do cosmology – the study of the evolution of our universe. Focusing on probes of Dark Energy, I will discuss some of the new...

Abstract: The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After...
