ATHENA workshop (Oct. 18th)

The Advanced Telescope for High ENergy Astrophysics (ATHENA) is a class L mission selected in the ESA's Cosmic Vision program, which will be launched in the early 2030s. This space observatory in the soft X-rays  wavelength range (0.1 eV -12 keV ) will be equipped with two instruments: the Wide Field Imager (WFI) and the X-ray Integral Field Unit (X-IFU). It will probe the hot and energetic Universe with unmatched sensitivity and precision. The ATHENA mission will provide a better understanding of the formation and evolution of hot baryonic matter large-scale structures, as well as the black holes growth mechanisms, especially in the young Universe. The ATHENA mission will also make it possible to study the gamma rays bursts as well as the coupling of stellar winds to planteray atmospheres and magnetospheres. These energetic phenomena are coupled with the interstellar matter of the host galaxies (structures in filaments, polarization, accretion disk, matter ejection, galactic fountain, metal enrichment ). The ATHENA mission will contribute to giving a multi-wavelength (by association with SKA, ALMA, ELT, ...) and multi-messenger (by association with LISA) vision of our Universe.

The goals of this one-day workshop are:

1. to  present the ATHENA mission, its possibilities, its scientific challenges
2. to discuss the science cases related to interstellar medium in the Milky way and external galaxies
3. to identify the laboratory astrophysics challenges that should be addressed in physical chemistry, spectroscopy or dynamics already now to prepare the mission.
