CLASH: Discovery of a Bright z~6.2 Dwarf Galaxy Quadruply Lensed by MACS J0329.6-0211
A. Zitrin, J. Moustakas, L. Bradley +22
We report the discovery of a z_{phot}=6.18^{+0.05}_{-0.07} (95% confidence level) dwarf galaxy, lensed into four images by the galaxy cluster MACS J0329.6-0211 (z_{l}=0.45). The ga…
Cluster-Cluster Lensing and the Case of Abell 383
Adi Zitrin, Yoel Rephaeli, Sharon Sadeh +8
Extensive surveys of galaxy clusters motivate us to assess the likelihood of cluster-cluster lensing (CCL), namely, gravitational-lensing of a background cluster by a foreground cl…
A Precise Cluster Mass Profile Averaged from the Highest-Quality Lensing Data
Keiichi Umetsu, Tom Broadhurst, Adi Zitrin +3
We outline our methods for obtaining high precision mass profiles, combining independent weak-lensing distortion, magnification, and strong-lensing measurements. For massive cluste…
Cluster Lensing And Supernova survey with Hubble (CLASH): An Overview
Marc Postman, Dan Coe, Narciso Benitez +42
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a 524-orbit multi-cycle treasury program to use the gravitational lensing properties of 25 galaxy clusters to accura…
The Cluster Lensing and Supernova Survey with Hubble (CLASH): Strong Lensing Analysis of Abell 383 from 16-Band HST WFC3/ACS Imaging
A. Zitrin, T. Broadhurst, D. Coe +38
We examine the inner mass distribution of the relaxed galaxy cluster Abell 383 in deep 16-band HST/ACS+WFC3 imaging taken as part of the CLASH multi-cycle treasury program. Our pro…
A Weak Lensing Detection of the Cosmological Distance-Redshift Relation Behind Three Massive Clusters
Elinor Medezinski, Tom Broadhurst, Keiichi Umetsu +2
The amplitude of weak lensing should increase with source distance, rising steeply behind a lens and saturating at high redshift, providing a model-independent means of measuring c…
