Are High-EW LAEs good analogs for the earliest galaxies? A study on the ionizing conditions and gas properties of LAEs at $2\lesssim z\lesssim7
Lyman-$\alpha$ emitters (LAEs) are frequently proposed as analogs of the low-mass, metal-poor galaxies thought to dominate cosmic reionization. In particular, galaxies with large Ly$\alpha$ equivalent widths (EWs) are expected to have not experienced significant chemical enrichment. We test this hypothesis using a samp...
