| Abstract: |
Euclid is the ESA mission to explore the dark universe in the next decade.
Launched on the 1st of July 2023, Euclid is orbiting around the Lagrange L2 point and
will map the 3D distribution of billions of galaxies and dark matter associated with
them. It will hence measure the large-scale structures of the Universe across 10 billion
light years, revealing the history of its expansion and the growth of structures during
the last three-quarters of its history. The Euclid Consortium (EC) is in charge of processing all the Euclid data, of which only the most scientifically valuable data will be
released through the Euclid Science Archive System (ESAS) during 6 years of mission
lifetime: images, various types of catalogues and spectra. Regarding data release contents, it is planned to combine Euclid observations with ground-based images obtained
from several telescopes, and a huge images collection, catalogues and spectra. At the
end of 2023, the first science ready data products of the Early Release Observations
(EROs) shall be published in ESAS. At the same time, the first data of the EC pipeline
will be made available in ESAS too but only to EC members. The first public release,
DR1 is planned by the end of 2025. In the meantime, the science archive already hosts
simulated images, catalogues and spectra that were used to exercise the scientific exploitation. Thus, in order to demonstrate how to explore, visualise and analyse the first
public data, in the context of this Focus Demo, we have shown the latest functionalities
of the archive and the tools available for the users, such as the ESA Euclid Astroquery
and ESA Datalabs Science Exploitation Platform among others. |
