A REMARKABLY LUMINOUS GALAXY AT Z = 11.1 MEASURED WITH HUBBLE SPACE TELESCOPE GRISM SPECTROSCOPY
ABSTRACT We present Hubble WFC3/IR slitless grism spectra of a remarkably bright z ≳ 10 galaxy candidate, GN-z11, identified initially from CANDELS/GOODS-N imaging data. A significant spectroscopic continuum break is detected at <?CDATA $\lambda =1.47\pm 0.01\;\mu {\rm{m}}$?> <?MML <mml:math> <mml:mi>λ</mml:mi> <mml:mo>=</mml:mo> <mml:mn>1.47</mml:mn> <mml:mo>±</mml:mo> <mml:mn>0.01</mml:mn> <mml:mspace width="0.25em"/> <mml:mi>&mgr;</mml:mi> <mml:mi mathvariant="normal">m</mml:mi> </mml:math>?> …
