摘要: We present results of a ground-based near-infrared campaign with Palomar TripleSpec, Keck NIRSPEC, and Gemini GNIRS to target two samples reddened active galactic nucleus (AGN) candidates from the 31 deg$^2$ Stripe 82 X-ray survey. One sample, which is $\sim$89\% complete $K 4$, Vega). The fainter sample ($K>17$, Vega) represents pilot program follow-up four sources parent 34 that are not detected in single-epoch SDSS catalog have {\it WISE} quasar colors. All twelve broad-line AGNs (at least one permitted emission line has FWHM exceeding 1300 km s$^{-1}$) span redshift range $0.59 0.5$) greater percentage high luminosities ($L_{\rm X,full} > 10^{44}$ erg s$^{-1}$). Such outflows may be consistent paradigm represent transitory phase AGN evolution as described by major merger model for black hole growth. Results our demonstrate proof-of-concept selection technique successful discovering quasars at $z 1$ missed optical surveys.
