Lens Model and Time Delay Predictions for the Sextuply Lensed Quasar SDSS J2222+2745
Keren Sharon, Matthew B. Bayliss, Hakon Dahle +7
SDSS J2222+2745 is a galaxy cluster at z=0.49, strongly lensing a quasar at z=2.805 into six widely separated images. In recent HST imaging of the field, we identify additional mul…
The systematics of strong lens modeling quantified: the effects of constraint selection and redshift information on magnification, mass, and multiple image predictability
Traci L. Johnson, Keren Sharon
Until now, systematic errors in strong gravitational lens modeling have been acknowledged but never been fully quantified. Here, we launch an investigation into the systematics ind…
Revised Lens Model for the Multiply-Imaged Lensed Supernova, "SN Refsdal", in MACS J1149+2223
Keren Sharon, Traci L. Johnson
We present a revised lens model of MACS J1149+2223, in which the first resolved multiply-imaged lensed supernova was discovered. The lens model is based on the model of Johnson et…
Lens models and magnification maps of the six Hubble Frontier Fields clusters
Traci L. Johnson, Keren Sharon, Matthew B. Bayliss +3
We present strong-lensing models, as well as mass and magnification maps, for the cores of the six HST Frontier Fields galaxy clusters. Our parametric lens models are constrained b…
