We present the Data Release 9 Quasar (DR9Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objects that were targeted as quasar candidates during the survey, are spectrocopically confirmed as quasars via visual inspection, have luminosities Mi[z = 2] 2.15 (61 931) is ~2.8 times larger than the number of z > 2.15 quasars previously known. Redshifts and FWHMs are provided for the strongest emission lines (C iv, C iii], Mg ii). The catalog identifies 7533 broad absorption line quasars and gives their characteristics. For each object the catalog presents five-band (u, g, r, i, z) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains X-ray, ultraviolet, near-infrared, and radio emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3600−10 500 A at a spectral resolution in the range 1300 < R < 2500; the spectra can be retrieved from the SDSS Catalog Archive Server. We also provide a supplemental list of an additional 949 quasars that have been identified, among galaxy targets of the BOSS or among quasar targets after DR9 was frozen.

Constraint on neutrino masses from SDSS-III/BOSS Lyα forest and other cosmological probes (2014, methodology): “he neutrino mass bound at 95% C.L. are +0.02 eV and 0:01 eV for AGN and SN feedbacks respectively in the Ly+ CMB conﬁguration. High-density absorbers: In [1], we used the DR9 quasar catalog of BOSS [75] and we rejected all quasars that are ﬂagged as having damped Lyman alpha (DLA) or detectable Lyma”
The one-dimensional power spectrum from the SDSS DR14 Lyα forests (2018, methodology): “Because a fraction of the quasars selected in the DR9 analysis of PYB13 are included in the present work, the combined statistical error overestimates the error on the difference.”
Nuclear activity versus star formation: emission-line diagnostics at ultraviolet and optical wavelengths (2015, background): “…detected routinely in quasars and galaxies out to high redshifts, although the lack of published measurements prevented us from inserting them in the present study (e.g., Humphrey et al. 2007; Hainline et al. 2011; Pâris et al. 2012; Alexandroff et al. 2013; Pâris et al. 2014; Lusso et al. 2015).”
THE DISCOVERY OF THE FIRST “CHANGING LOOK” QUASAR: NEW INSIGHTS INTO THE PHYSICS AND PHENOMENOLOGY OF ACTIVE GALACTIC NUCLEI (2014, background): “However, a later 2010 SDSS-III (Eisenstein et al. 2011) BOSS (Dawson et al. 2013) spectrum revealed that the broad Hβ component completely disappeared, yet a weak, broad Hα component remained visible (i.e., Type 1.9 state); it was no longer included in subsequent SDSS-III quasar catalogs from DR9 an”
Baryon acoustic oscillations in the Lyα forest of BOSS DR11 quasars (2014, background): “The spectra of all quasar targets were visually inspected (Pâris et al., 2012, 2014) to correct for misidentifications or inaccurate redshift determinations and to flag broad absorption lines (BALs).”
The Sloan Digital Sky Survey Quasar Catalog: Twelfth data release (2016, methodology): “The quasar continuum is estimated using a linear combination of four principal components as described in Pâris et al. (2012).”
The Sloan Digital Sky Survey quasar catalog: tenth data release (2013, methodology): “This definition is the same as in DR9Q (Pâris et al. 2012).”
Baryon acoustic oscillations from the complete SDSS-III Ly$\alpha$-quasar cross-correlation function at $z=2.4$ (2017, methodology): “The spectra of all quasar targets were visually inspected (Pâris et al. 2012, 2014, 2017) to correct for misidentifications, to flag broad absorption lines (BALs), and to determine the quasar redshift used in the analysis.”
