JADES | Possible Population III signatures at z=10.6 in the halo of GN-z11

F277W NIRCam image of the central ~ 1.7" around GN-z11 illustrating the location of the MSA shutters during the first NIRSpec-MOS observations in February 2023 (tilted boxes, with boxes of the same color being associated with the same configuration), extraction region of the HeII clump (red square) and of the HeII extended emission (yellow box). The white circle indicates the absolute uncertainty of the MSA target acquisition (hence the shutters' footprints are uncertain by this amount). North is up and East is to the left.
