We report the discovery of a complete Einstein ring around the elliptical galaxy NGC 6505, at z = 0.042. This is the first strong gravitational lens discovered...
Euclid: an automated system to match Rubin transient alerts to Euclid observations
The Vera C. Rubin observatory is expected to produce 10 million transient alerts per night in ugrizy filters, whilst Euclid is a visible to near-infrared space...
Euclid: An emulator for baryonic effects on the matter bispectrum
The Euclid mission and other next-generation large-scale structure surveys will enable high-precision measurements of the cosmic matter distribution...
Euclid: Asteroid rotation periods from the Euclid Ecliptic Survey
The Euclid Ecliptic Survey was conducted during the calibration phase of the mission, from 23 to 31 December 2023, as a campaign to study Solar System objects...
Euclid: Calibrating photometric redshifts with spectroscopic cross-correlations
Cosmological constraints from key probes of the Euclid imaging survey rely critically on the accurate determination of the true redshift distributions, n(z), of...
Euclid: Constraining dark energy coupled to electromagnetism using astrophysical and laboratory data
In physically realistic, scalar-field-based dynamical dark energy models (including, e.g., quintessence), one naturally expects the scalar field to couple to...
Euclid: Constraining ensemble photometric redshift distributions with stacked spectroscopy
Context. The ESA Euclid mission will produce photometric galaxy samples over 15 000 square degrees of the sky that will be rich for clustering and weak lensing...
Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes
Context. The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic...
Euclid: Cosmological forecasts from the void size function
The Euclid mission - with its spectroscopic galaxy survey covering a sky area over 15 000 deg 2 in the redshift range 0.9 < z < 1.8 - will provide a sample of...
