Maps of the narrow component of Hα for LBQS0109 (top) and HB8903 (bottom); the white contours trace the [Oiii]λ5007 velocity blue-shift shown in Fig. 3. The contours represent the velocity –300, –275, and –250 km s^-1 for LBQS0109, and –150, –100, and –50 km s^-1 for HB8903. Star formation traced by Hα_nar  is heavily suppressed in the S–W and S–E for region for LBQS0109 and HB8903, respectively, where the outflow traced by [Oiii]λ5007 is fastest. Black squares indicate the nine regions where we extracted the corresponding H-band spectra shown in the right panels of Fig. 1.
