Infrared spectroscopic confirmation of <i>z</i> ∼ 2 photometrically selected obscured quasars

The census of obscured quasar populations is incomplete, and remains a major unsolved problem, especially at higher redshifts, where we expect greater density galaxy formation activity. We present Gemini GNIRS near-infrared spectroscopy 24 luminous candidates from the Sloan Digital Sky Survey's Stripe 82 region. targets were photometrically selected using WISE/W4 selection technique that optimized to identify IR-bright heavily-reddened/optically-obscured $z>1$. detect emission lines ${\rm H\alpha}$, H\beta}$, and/or ${\rm[ O~III]}$ in 23 sources allowing us measure spectroscopic redshifts range $1<z<3$ with bolometric luminosities spanning $L=10^{46.3}-10^{47.3}$ erg s$^{-1}$. observe broad $10^3-10^4$ km s$^{-1}$ Balmer emissions large H\alpha}/{\rm H\beta}$ ratios, directly heavily reddened rest-frame optical continuum several sources, suggesting high extinction ($A_V\sim7-20$ mag). Our observations demonstrate such optical/infrared photometric successfully recovers high-redshift quasars. successful identification previously undetected red, suggests there are more quasars yet be discovered.
