Illuminating protogalaxies? The discovery of extended Lyman-α emission around a QSO at z = 4.5
We have discovered extended Lyman-α emission around a z = 4.5 QSO in a deep long-slit spectrum with Keck/LRIS at moderate spectral resolution (R ≈ 1000). The line emission extends 5 arcsec beyond the continuum of the QSO and is spatially asymmetric. This extended line emission has a spectral extent...
