The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients,
dark matter and dark energy, remains unknown. Euclid is a medium-class mission in the Cosmic Vision 2015–2025 programme... Read More about Euclid: I. Overview of the Euclid mission.

In the cold dark matter (CDM) paradigm, an association between the hypothetic dark matter (DM) and its stellar counterpart is expected. However, parametric strong-lensing studies of galaxy clusters often display misleading features: DM components on... Read More about Mass and light in galaxy clusters: The case of Abell 370.
