The FIRST-2MASS Red Quasar Survey. Glikman E., Helfand D.J., White R.L., Becker R.H., Gregg M.D., Lacy M. <Astrophys. J., 667, 673-703 (2007)> =2007ApJ...667..673G

Description: Spectroscopic follow-up of our candidates was carried out over a 5 year period at four observatories at both optical and near-infrared wavelengths. A majority of the optical spectra were obtained at the 10m W.M. Keck Observatory in Hawaii using the ESI and, to a lesser extent, the LRIS spectrographs. A handful of spectra were obtained with the Kast spectrograph on the 3m Shane Telescope at Lick Observatory. The near-infrared observations, spanning 0.8-2.5um, were conducted at the NASA Infrared Telescope Facility (IRTF) with the SpeX spectrograph Five near-infrared spectra, spanning 0.95-2.5um, were obtained at the MDM Observatory on Kitt Peak with the TIFKAM infrared camera in spectroscopic mode.
