Cosmological Parameter Determination in Free-Form Strong Gravitational Lens Modeling
M. Lubini, M. Sereno, J. Coles +2
We develop a novel statistical strong lensing approach to probe the cosmological parameters by exploiting multiple redshift image systems behind galaxies or galaxy clusters. The me…
A Sampling Strategy for High-Dimensional Spaces Applied to Free-Form Gravitational Lensing
Mario Lubini, Jonathan Coles
We present a novel proposal strategy for the Metropolis-Hastings algorithm designed to efficiently sample general convex polytopes in 100 or more dimensions. This improves upon pre…
Probing the dark matter issue in f(R)-gravity via gravitational lensing
M. Lubini, C. Tortora, J. Näf +2
For a general class of analytic f(R)-gravity theories, we discuss the weak field limit in view of gravitational lensing. Though an additional Yukawa term in the gravitational poten…
On the over-concentration problem of strong lensing clusters
M. Sereno, Ph. Jetzer, M. Lubini
Lambda cold dark matter paradigm predicts that galaxy clusters follow an universal mass density profile and fit a well defined mass-concentration relation, with lensing clusters be…
A multi-wavelength strong lensing analysis of baryons and dark matter in the dynamically active cluster AC 114
M. Sereno, M. Lubini, Ph. Jetzer
Strong lensing studies can provide detailed mass maps of the inner regions even in dynamically active galaxy clusters. It is shown that proper modelling of the intracluster medium,…
