Extracted one-dimensional spectra for four blobs from 6.5 m MMT long-slit spectroscopy (Blobs 1, 2, and 4) and the AGES (Blob 3; Kochanek et al., in preparation). For Blobs 1 and 2, there is no other emission line visible up to 6500 Å. The broad Lyα profiles and the absence of other emission lines indicate that Blobs 1 and 2 are true Lyα blobs. These two blobs have almost the same redshifts (z = 2.318) within δz 0.001. Their spectra do not show any AGN signatures (e.g., CIVλ1549). Neither of these blobs is X-ray detected (Section 3.2). Blobs 3 and 4 show other broad emission lines (e.g., C IV λ1549 and/or C III λ1909), indicating that these blobs host QSOs. Unlike Blobs 1 and 2, these blobs are X-ray detected [L_X(2–7 keV) = 1.6–4.1 × 10⁴⁴ erg s⁻¹]. Because of the blending in the B_W images, the Blob 4 spectrum contains an interloper, an [O II] emitter at z 0.266 (Hγ, Hβ, and [O III] lines). The shaded regions indicate where strong sky lines are present.
