Spectroscopic confirmation of three z-dropout galaxies at z= 6.844–7.213: demographics of Lyα emission in z∼ 7 galaxies

We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in
the Subaru Deep Field and Great Observatories Origins Deep Survey's northern field. For 3
out of 11 objects, we detect an emission line at∼ 1 μm with a signal-to-noise ratio of∼ 10.
The lines show asymmetric profiles with high weighted skewness values, consistent with
being Lyα, yielding redshifts of z= 7.213, 6.965, and 6.844. Specifically, we confirm the z=

We present the results of our ultra-deep Keck/DEIMOS spectroscopy of z-dropout galaxies in
the Subaru Deep Field and Great Observatories Origins Deep Survey's northern field. For 3
out of 11 objects, we detect an emission line at∼ 1um with a signal-to-noise ratio of∼ 10.
The lines show asymmetric profiles with high weighted skewness values, consistent with
being Lya, yielding redshifts of z= 7.213, 6.965, and 6.844. Specifically, we confirm the z=
