Description
The European Space Agency’s Euclid mission, launched to map the geometry of the dark Universe, aims to uncover the nature of dark energy and dark matter by measuring the shapes, redshifts, and clustering of galaxies over a third of the sky. Euclid’s Visible Imaging Channel (VIS) will provide deep, high-resolution imaging essential for precision cosmology.
The UK’s national computing infrastructure, IRIS, plays a critical role in processing and analyzing Euclid data, providing the computational power necessary to handle the mission’s unprecedented volume of observations. This infrastructure supports the development, validation, and application of scientific pipelines crucial to achieving Euclid’s ambitious science goals.
This presentation will highlight UK Euclid science activities conducted on IRIS, including:
Weak Lensing Galaxy Shape Measurement — Precise extraction of galaxy shapes for weak lensing cosmology, a key probe of dark matter and dark energy.
PSF Reconstruction Analysis — Accurate modelling of the point spread function to mitigate systematic errors in shape measurements.
Legacy Science Applications — Leveraging Euclid data for broader astrophysical studies, including strong lensing, galaxy formation, and galaxy cluster analyses.
This talk will emphasize how IRIS facilitates these science goals and accelerates progress towards realizing Euclid’s mission objectives.
