Abstract
We present a strong-lensing analysis of the cluster PSZ1 G311. 65− 18.48, based on Hubble Space Telescope imaging, archival VLT/MUSE spectroscopy, and Chandra X-ray data. This cool-core cluster (z= 0.443) lenses the brightest lensed galaxy known, dubbed the" Sunburst Arc"(z= 2.3703), a Lyman continuum (LyC) emitting galaxy multiply imaged 12 times. We identify in this field 14 additional strongly lensed galaxies to constrain a strong-lens model and report secure spectroscopic redshifts of four of them. We measure a projected cluster core mass of M (< 250 kpc)=
