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...
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...
Exploring the correlation between dark matter, intracluster light, and globular cluster distribution in SMACS0723
We present a free-form model of SMACS0723, the first cluster observed with JWST. This model does not make any strong assumptions on the distribution of mass...
Exploring the nature of dark matter with the extreme galaxy AGC 114905
AGC 114905 is a dwarf gas-rich ultra-diffuse galaxy seemingly in tension with the cold dark matter (CDM) model. Specifically, the galaxy appears to have an...
