Extended Data Fig. 7: Spectral comparison of the two cores in J0841.
From: A hidden population of high-redshift double quasars unveiled by astrometry
The red and cyan lines are for the northwestern (NW) core and the southeastern (SE) core, respectively. The circled-cross symbol denotes the telluric absorption region masked out in the spectra. There are notable differences in the strengths of the broad emission lines after the flux of the SE core is scaled to roughly match the continuum flux of the NW core. There are also slight differences in the continuum shape and strengths in certain intervening absorption lines.
