Can Blue UV-Bright Galaxies Drive Reionization at Cosmic Dawn? An $M_{\rm UV}=-19.6$ Galaxy with $f_{\rm esc}\approx0.85$ at $z=9.244$
We revisit EBG-1, a gravitationally lensed galaxy at $z = 9.244$, using newly obtained deep (14 hr) JWST/NIRSpec G235M ($R \sim 1000$) spectroscopy. EBG-1 is one of the bluest galaxies observed at $z > 9$. Along with its remarkably blue continuum of $β= -2.99 \pm 0.15$, we find very weak nebular emi
