The 11th Indo-French Astronomy School (IFAS11) took place this week at the Château de Goutelas near Lyon, gathering young astronomers and researchers from around the world for an intensive exploration of advanced astronomical techniques, with a focus on 3D spectroscopy.

The event, co-organized by the CRAL at Université Lyon 1 and the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune, India, with support from the OSU, emphasized integral field spectroscopy (IFS), a critical tool in modern astrophysics. Participants engaged in lectures and hands-on research projects focused on analyzing complex data from state-of-the-art instruments like the MUSE spectrograph, developed for the European Southern Observatory’s Very Large Telescope (VLT) in Chile.
Over seven days, the 11 students, representing 6 different nationalities from 3 continents, tackled challenging research projects on gravitational lensing, galaxy dynamics, and active galactic nuclei. Guided by instructors from CRAL and IUCAA, they gained practical experience with cutting-edge astronomical data-processing methods.
IFAS11, funded by academic and governmental partners including the CNRS and the Scientific Council of the Observatoire de Lyon, continues its tradition of fostering Franco-Indian collaboration while welcoming international participants. The program primarily targets PhD students and advanced master’s candidates.
