VizieR Online Data Catalog: SDSS & MMT obs. of extremely massive QSOs & gal. (Yoon+, 2019)
Abstract
For three massive quasars (J135354.89+134228.5, J155846.72+223549.6, and J170441.38+604430.5), we observed galaxies in the radius of ~0.5deg from these quasars using the Hectospec on the MMT. The Hectospec wavelength coverage is from ~3700Å to ~8500Å with a spectral resolution of ~6.2Å.
