| Abstract | ESA maintains a repository for storing and distributing Euclid High-Level Science Products (HLSPs). These include a range of different data sets and software/tools, all associated with scientific papers on Euclid that have been accepted in peer-reviewed journals. This service is offered to facilitate access, use, and further development of Euclid-related HLSPs by providing a shared reference repository for the scientific community. The HLSP repository complements ESA Euclid Data Space (EDS) and the Euclid Scientific Archive, which provide access to the Euclid data releases. |
| Description | Products include cutouts of the quasars discussed in the associated scientific paper: "Euclid: Discovery of 31 new quasars at 6.6 < z < 7.8", available here: https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_discovers_the_most_ancient_quasar_in_the_Universe |

| Temporal Coverage | The quasar search described in this work utilised Euclid Wide Survey imaging data acquired between 14 February 2024 and 11 August 2025, as shown in https://www.esa.int/Science_Exploration/Space_Science/Euclid/Euclid_discovers_the_most_ancient_quasar_in_the_Universe |
| Mission Description | Euclid is an ESA science mission that was launched on the 1st of July 2023 to survey one third of the extragalactic sky with the aim to investigate the origin of the accelerating expansion of the Universe and the nature of dark energy, dark matter and gravity. Euclid maps the geometry of the Universe, reconstructing the evolution of large-scale structures over the past 10 billion years. |
