A vision transformer classifier trained on simulated and real Euclid data recovers all known strong lenses in test sets and finds 8 Grade A plus 26 Grade B new candidates in the Q1 data.
CLOE pipeline produces forecasts showing Euclid can reach FoM >400 for dark energy w0 and wa by combining primary probes on synthetic data.
Bulge-disc decomposition on 2445 galaxies with I_E < 21 in Euclid ERO Perseus data shows B/T spanning 0-1, single-Sérsic radii as intermediates, and 0.3 mag median bulge-disc color differences driven by disc-dominated systems.
CLOE has been extended to model magnification bias, massive neutrinos, and modified gravity for Euclid probes and validated via posterior sampling on synthetic data.
