Chasing Cosmic Reionization: An Extremely Faint Highly Magnified Source at $z=5.66$ with high $\xi_{\rm ion}$
We present JWST NIRSpec IFU spectroscopic measurements of one of the faintest (M$_{UV}>-13.6$) known ionizing sources at $z=5.66$, dubbed Small And Lensed Source Arc, SALSA. This source is highly magnified ($\mu>100$) by the lensing galaxy cluster Abell 2744, providing a unique opportunity to investigate the physical p...
