Euclid is a mission of the European Space Agency that is designed to constrain the properties of dark energy and gravity via weak gravitational lensing and...
Euclid preparation. XVII. Cosmic Dawn Survey: Spitzer Space Telescope observations of the Euclid deep fields and calibration fields
We present a new infrared survey covering the three Euclid deep fields and four other Euclid calibration fields using Spitzer Space Telescope's Infrared Array...
Euclid preparation. XXXII. Evaluating the weak-lensing cluster mass biases using the Three Hundred Project hydrodynamical simulations
The photometric catalogue of galaxy clusters extracted from ESA Euclid data is expected to be very competitive for cosmological studies. Using dedicated...
Euclid preparation: LXII. Simulations and non-linearities beyond Lambda cold dark matter. 1. Numerical methods and validation
To constrain cosmological models beyond ACDM, the development of the Euclid analysis pipeline requires simulations that capture the non-linear phenomenology of...
Euclid: Searches for strong gravitational lenses using convolutional neural nets in Early Release Observations of the Perseus field
The Euclid Wide Survey (EWS) is predicted to find approximately 170 000 galaxy-galaxy strong lenses from its lifetime observation of 14 000 deg 2 of the sky...
Examining the self-interaction of dark matter through central cluster galaxy offsets
While collisionless cold dark matter models have been largely successful in explaining a wide range of observational data, some tensions still exist, and it...
Expected Number of Massive Galaxy Relics in the Present Day Universe
The number of present day massive galaxies that have survived untouched since their formation at high-z is an important observational constraint to the...
