PACE members participated in the international Athena-WFI meeting (see link for the detailed programme), held on the end of November at the Faculty of Sciences of the University of Lisbon. The Wide Field Imager (WFI) is an instrument that will be mounted on the Athena Space Observatory, an X-ray telescope designed to address fundamental questions in Astrophysics involving high energies. The launch is scheduled for 2031, and PACE explored during the meeting potential synergies between Athena and millimetre and submillimetre Astronomy.
