VizieR Online Data Catalog: Opt. & NIR spectral atlas of 16 2MASS NIR-red AGNs (Kim+, 2018)

Our sample is drawn from the 29 2MASS-based red AGNs observed with the WFPC2 on the Hubble Space Telescope (HST) in Marble+ (2003ApJ...590..707M). Among the 29 NIR-red AGNs, we select 16 AGNs at z~0.3 (from 0.139 to 0.411) for which the redshifted Pα or Pβ line is observable within the sky window wavelength range.

We performed NIR spectroscopic observations with four telescopes and their respective instruments. First, NIR spectra of nine NIR-red AGNs were obtained with the cross-dispersed mode of the Gemini Near-infrared Spectrograph (GNIRS) on the 8.1m Gemini-North telescope; spectral coverage from ~1um to ~2.1um with a spectral resolution of R~2600. Second, we used the SpeX on the 3.0m NASA Infrared Telescope Facility (IRTF) for five NIR-red AGNs; R~2000 across 0.7-2.55um. Third, for two NIR-red AGNs, we used the Folded-port Infrared Echellette (FIRE) on the 6.5m Magellan Baade telescope; 0.82-2.51um with R~3600. Fourth, an NIR spectrum of one NIR-red AGN was obtained with the Infrared Camera and Spectrograph (IRCS) on the 8.2m Subaru telescope. See section 2.2 for further explanations.

In addition to the NIR spectra, we obtained optical spectra for 12 NIR-red AGNs. Two (G. Canalizo & M. Lazarova) of us observed 10 NIR-red AGNs using the Echellette Spectrograph and Imager (ESI) on the Keck II telescope with a spectral wavelength range of 3900Å to 11000Å and a spectral resolution of R~4000. For the remaining two NIR-red AGNs, we obtained the optical spectra from Data Release 12 (DR12) of the Sloan Digital Sky Survey (SDSS; 3800Å to 9200Å, with a spectral resolution of 1500-2500). See section 2.3.
