Upper panel:
UIST HK-Grism spectrum of the z=6.41 quasar SDSS J1148+5251
(red). The broad MgII emission line is marked. The
blue curve shows the best fit model comprising a power law continuum
(spectral index, alpha=0.2), a broadened FeII template and a broad
MgII line. Lower panel: The residual spectrum after subtraction of the power law continuum and FeII template (red). The best fit to the broad MgII doublet (FWHM=6000 km/s) is also shown here (blue). The cyan region shows the 1-sigma noise. See the Research News section (below) for more details! |
