Strong lensing analysis of Abell 2744 with MUSE and Hubble Frontier Fields images

Understand

We present an analysis of MUSE observations obtained on the massive Frontier Fields cluster Abell 2744.

• This new dataset covers the entire multiply-imaged region around the cluster core.
• We measure spectroscopic redshifts for HST-selected continuum sources together with line emitters blindly detected in the datacube.
• The combined catalog consists of 514 spectroscopic redshifts (with 414 new identifications), including 156 cluster members and 326 magnified background sources.
