Dark Matter In Galaxy Clusters: Parametric Strong-Lensing Approach

Di: Ava

We present a parametric strong lensing analysis of three massive clusters. Our aim is to probe the inner shape of dark matter haloes, in particular the existence of a core. We adopt the following

Universe's Dark Matter Seen Through Photos of Gravitational Lensing ...

Gravitational lensing provides a direct means for measuring the masses of galaxies and galaxy clusters. Provided that enough constraints are available, one might even hope to obtain a Light unaffiliated mass clumps (LUMCs), i.e. dark matter (DM) components without any stellar counterparts, have been reported in strong lensing mass reconstructions of MACS Galaxy clusters as gravitational lenses play a unique role in astrophysics and cosmology: they permit mapping the dark matter distribution on a range of scales; they reveal

Marceau Limousin1 Abstract. In the cold dark matter paradigm, the association between the hypothetic dark matter and its stellar counterpart is expected. However, parametric strong

With real data, our strong-lensing constraints on w (z) are consistent with those derived from other cosmological probes. We confirm that strong lensing cosmography with We present a parametric strong-lensing analysis of three massive galaxy clusters for which Hubble Space Telescope imaging is available, as well as spectroscopy of multiply imaged
