Abstract: The increasingly neutral intergalactic gas at $z>6$ impacts the Lyman-$alpha$ flux observed from galaxies. One luminous galaxy, COLA1, stands out because of its unique double-peaked Ly$alpha$ line at $z=6.6$, unseen in any simulation of reionization. Here we present JWST/NIRCam wide-field slitless spectroscopy in a 21 arcmin$^2$ field centered on COLA1. We find 141 galaxies spectroscopically-selected through the [OIII]($lambda4969,5008$) doublet at $5.35M_{rm UV}>-19.5$).arXiv:2404.10040v1 Announce Type: new
