Quasars with Extreme Broad Emission Line Equivalent Widths in SDSS3-BOSS The recent survey by Ross et al. of extremely red quasars in SDSS3-BOSS (with r - W4_AB > 7.5) contains a surprisingly high fraction of quasars with large rest equivalent widths (REWs) in their broad emission lines. For example, ~45% of the non-BAL quasars at redshifts z >~ 2 in that sample have REW(CIV) > 150A compared to only ~1.5% in BOSS quasars generally. The most extreme cases have UV continua that appear too weak to power the observed emission line fluxes. The extreme red colors of these quasars suggest that the large REWs are caused by line-of-sight suppression of the UV continuum rather than unusually strong broad emission lines. However, it is not obvious what physical mechanism(s) can suppress the UV continuum enough without also suppressing the broad line fluxes. We discuss several possibilities, added by new spectra from the VLT XShooter designed to address this question. We also describe a broader study of BOSS quasars that reveals many cases with extreme REWs but roughly normal broad-band colors. The origins of extreme REWs in these "normal" cases appear even more puzzling. A better theoretical understanding of these phenomena could have important implications long-standing questions about structure and physical properties of the BLR, the origins of the Baldwin Effect, and the relationship of Type 1 and Type 2 quasars in the Unified Model.
