The impact and mitigation of broad absorption line quasars in Lyman$-\alpha$ forest correlations

Correlations in and with the flux transmission of the Lyman$-\alpha$ (Ly$\alpha$) forest in the spectra of high-redshift quasars are powerful cosmological tools, yet these measurements can be compromised if the intrinsic quasar continuum is…
