We stand in solidarity with all our colleagues who are victims of the attacks on science, particularly by the Trump administration. We categorically oppose all forms of censorship and reaffirm our unwavering commitment to the fundamental values of science: freedom, integrity and openness. We are committed to defending these values, and we invite you to join us in this commitment, particularly through Stand Up for Science actions.
The James Webb Space Telescope (JWST) is transforming our understanding of trans-Neptunian objects (TNOs), the icy remnants of planetary formation. As part of the DiSCo-TNOs project, researchers have used JWST’s near-infrared data to identify two distinct groups among spectrally red TNOs, believed to be rich in organics. The key difference between these groups is the presence of surface ices—particularly methanol (CH₃OH) ice.
Dan Pineau, from the AMIS team, brilliantly defended his thesis on the fusion of imaging and spectroscopy data, with application to JWST data. Thesis carried out under the supervision of Alain Abergel (IAS) and François Orieux (L2S). He is now a new doctor at the University of Paris-Saclay, and will be heading for Luxembourg. Congratulations to him!
