From the ISM to exoplanets and high-redshift galaxies: new insights from JWST
Symposium of the XVII SEA meeting: https://sea2026.ice.csic.es
Sala August, Palacio Ferial y de Congresos, Tarragona, Spain
Scientific rationale
Scientific rationale
The James Webb Space Telescope (JWST) has opened an unprecedented window into the Universe, enabling observations from our own Solar System to the most distant galaxies. Its unique combination of sensitivity, and spatial and spectral resolutions in the 0.6–28 μm range allows detailed studies of diverse astrophysical environments, from the interstellar medium and galaxies to exoplanetary atmospheres. The Spanish astronomical community has played a key role in JWST’s scientific development, and this symposium aims to highlight its contributions across multiple fields to enable scientific as well as technical discussions that might open new collaboration avenues.
The session is organized into three thematic blocks: i) Galaxies; ii) ISM and Stars; and iii) Solar System and Exoplanets. The first block will focus on galaxy formation and evolution, active galactic nuclei, star formation activity, and the properties of distant galaxies, including their stellar populations, dust, and gas content. The second block will explore the lifecycle of the interstellar medium, from star formation to stellar end-of-life ejecta that enrich the ISM with dust grains and complex molecules. Finally, the third block will cover atmospheric characterization of exoplanets, the study of planetary systems, and observations of comets, asteroids, and other small bodies.
This symposium will bring together the Spanish astronomical community working with JWST to discuss questions as follows:
How do galaxies form and evolve? How does AGN feedback shape galaxy evolution across cosmic time?
What insights can JWST provide on the formation and early/late evolution of stars and planetary systems?
How do observations of exoplanets and the Solar System’s small bodies inform models of their composition?
By combining observational results, theoretical modeling, and comparative studies across diverse environments, the session aims to provide a comprehensive overview of the Spanish contribution to JWST science and its impact on understanding the Universe from our own Solar System to the most distant galaxies.
