The Spanish participation in X-ray observatories: past, present and future symposium will be held within the framework of the XVI Scientific Meeting of the SEA (Granada). This symposium will showcase the Spanish participation in (and exploitation of) X-ray observatories from the past to the present, also looking out to the future. Encompassing a broad spectrum, our discussions will span diverse topics, including the development of instrumentation, for instance for WFM/eXTP (IEEC) or THESEUS (IAA, INTA, UV), as well as the development of on-board software, one example is SIRENA for Athena/X-IFU. Additionally, the symposium will delve into the exploitation of X-ray observations archival data via advanced analysis tools, enabling real-time tracking of the X-ray transient sky through machine-learning methodologies. Moreover, scientific simulations will take centre stage covering a breadth of topics from accreting compact objects such as black holes over their whole mass range and neutron stars, the hot gas around clusters of galaxies, distant gamma-ray bursts, supernova explosions and remnants, stars, white dwarfs, exoplanets and their parent stars, and the interstellar medium.
