Multiband image fusion under spectrally varying spatial blurs — Application to JWST data Multiband image fusion has been extensively studied in the literature of Earth observation. This task aims at recovering a multiband image of high spatial and high spectral resolutions from complementary measurements of lower spatial or spectral resolutions. While several methods developed in […]

New tools from wave topology for asteroseismology Asteroseismology studies waves in stars and uses them to infer what their internal structure is. Today, hundreds of stars of every kind show oscillations which allowed us to deduce their mass, radius, rotation rate, width of convective zone, etc. Wave topology proposes a new light under which to […]

Detecting Earth-analogs with radial velocities and photometry Abstract: Understanding how planets form and searching for life beyond Earth are two key goals in exoplanet research. To make progress on both fronts, it is crucial to discover Earth analogs. However, detecting them is a major challenge, as their faint signals are difficult to disentangle from astrophysical […]
