Hubble Space Telescope Combined Strong and Weak Lensing Analysis of the CLASH Sample: Mass and Magnification Models and Systematic Uncertainties
Adi Zitrin, Agnese Fabris, Julian Merten +23
We present results from a comprehensive lensing analysis in HST data, of the complete CLASH cluster sample. We identify new multiple-images previously undiscovered allowing improve…
A Free-Form Lensing Grid Solution for A1689 with New Mutiple Images
Jose M. Diego, T. Broadhurst, N. Benitez +6
Hubble Space Telescope imaging of the galaxy cluster Abell 1689 has revealed an exceptional number of strongly lensed multiply-imaged galaxies, including high-redshift candidates.…
Nonparametric reconstruction of the cosmic expansion with local regression smoothing and simulation extrapolation
Ariadna Montiel, Ruth Lazkoz, Irene Sendra +2
In this work we present a nonparametric approach, which works on minimal assumptions, to reconstruct the cosmic expansion of the Universe. We propose to combine a locally weighted…
BAO cosmography
Ruth Lazkoz, Jailson Alcaniz, Celia Escamilla-Rivera +2
Cosmography provides a model-independent way to map the expansion history of the Universe. In this paper we simulate a Euclid-like survey and explore cosmographic constraints from…
Improving Dark Energy Constraints with High Redshift Type Ia Supernovae from CANDELS and CLASH
Vincenzo Salzano, Steven A. Rodney, Irene Sendra +5
Aims. We investigate the degree of improvement in dark energy constraints that can be achieved by extending Type Ia Supernova (SN Ia) samples to redshifts z > 1.5 with the Hubble S…
Enabling Non-Parametric Strong Lensing Models to Derive Reliable Cluster Mass Distributions. WSLAP+
Irene Sendra, Jose M. Diego, Tom Broadhurst +1
In the strong lensing regime non-parametric lens models struggle to achieve sufficient angular resolution for a meaningful derivation of the central cluster mass distribution. The…
