Description
I will describe an 8-year spectroscopic search with IMACS on Magellan for the faintest Lyman-alpha emitters (LAEs) at z= 5.7. Our study has pushed the detection limit an order-of-magnitude fainter than the prominent narrow-band-imaging surveys,leading to the first robust measurement of the faint-end-slope of the luminosity function.
